Abstract: This paper deals with a DC-micro grid in an isolated island. The proposed method is composed of gearless wind power generation system, battery, and DC loads in DC distribution system. The battery can avoid DC over-voltages by absorbing the PMSG power during line-fault. In addition, the control schemes in this paper include the maximum power point tracking (MPPT) control and a pitch angle control for the gearless wind turbine generator. By means of the proposed method, high-reliable power can be supplied to DC distribution system during line-fault, and stable power supply from PMSG to the electrical power system after line-fault clearing can be achieved. The effectiveness of the proposed method is performed in a MATLAB/Simulink Rreg environment.

Abstract: Existing distribution networks have not been designed to accept extensive distributed generation (DG). The actual paradigm may change in the near future impelled by a worldwide increasing of DG penetration in distribution grids. This paper presents the status and content of DG Spanish legislation. Fundamental considerations are first discussed, exclusively regarding the grid-interconnection requirement. This paper also analyses the relationship between that guidelines and recognized international standard in a systematic way. Major requirements areas include general specifications, safety and protection strategies, and power quality requirements. Interconnecting DER with the electric power system is traditionally a complicated process that can be facilitated by improving international harmonization.

Abstract: In the last few years, the design of power electronics systems has been towards modularity. The focus has been on finding solutions for integration of distributed power electronics systems. Distributed systems set new requirements for control systems compared with the traditional centralized solutions. Using intelligent power electronics building blocks as a basis for power electronics systems results in reduced cost, easier reconfiguration, and improved reliability. A cascaded ring topology has become a prominent control solution. In many applications, accurate synchronization of the building blocks is of crucial importance; it is therefore essential to understand the factors that affect the synchronization accuracy. This paper addresses ring topology synchronization methods and the factors that define the overall synchronization accuracy. A new time-stamping-based synchronization method is presented, and its accuracy and jitter behavior are analyzed. Experimental results of synchronization jitter of the proposed method are presented.

Abstract: The latest developments in complex network theory have provided a new direction to power system research. Based on this theory a power system can be modelled as a graph with nodes and vertices and further analysis can help in identifying the important lines. This paper proposes a new betweenness index using the reactance of the transmission lines as the weight and criteria to measure of vulnerability of a power network. The reactance is a simplified measure of power flow in a lossless transmission line based on the power flow analysis equations. The weighted line index is defined as the reactance of the electric path taken to reach from one node to another node. More power is transmitted along the lines with less reactance, to reach from the source node to destination node, which gives the edges with less reactance a higher weight in the analysis. The analyzes have been carried out on the IEEE 39 bus system and IEEE 118 bus system. The new betweenness index can identify the critical lines of the system, either due to their position in the network or by the power they transmit along the network.

The measured impedance at the relaying point is greatly influenced in the presence of UPFC on the protected line or even on the near end of the next line. The measured impedance at relating point depends on many factors including the power system structural conditions, pre-fault loading, fault resistance, and UPFC structural and controlling parameters.

Abstract: Generally, an electronic ballast drives a fluorescent lamp at fixed operating frequency or by regulating the lamp current. Such methods can be used for the designed lamp type and power rating. This paper presents an automatic fluorescent lamp detection for electronic ballasts based on operating frequency and phase shift compensation. The classification of lamp power rating is based on the possibility weight distribution of the lamp operating frequency. Moreover, the phase shift compensation is also included in the detection algorithm in order to address the variations of the resonant circuit parameters. The results from simulation and experiment verify that an electronic ballast with the proposed detection algorithm can automatically detect and drive the fluorescent lamp at the correct lamp power rating.

Abstract: High speed solenoid valve is one of the key components in modern electronic controlled diesel fuel systems. Control quality of the fuel systems is greatly affected by unit to unit deviation of their electro-magnetic characteristics. Precise detection of the solenoid valve closure point is a feedback method to promote control quality by completing fuel injection control loop. Through mechanism modeling of the spill-valve solenoid used in electronic assemble fuel pump, the property of the valve closure point is analyzed, and its detection method and electric driving logic are proposed. Subsequently, a fuel injection feedback control algorithm is implemented in mass-production engine control unit. Fuel bench tests show that, the valve closure point can be precisely recognized by the detection method, and in cooperation with the feedback control algorithm, cylinder to cylinder unevenness of the fuel injection quantities can be reduced, which consequently leads to the promotion of the control quality of the fuel injection system.

Abstract: User interaction is an essential feature in the design of an interactive game. Most existing games receive inputs from users via conventional devices such as keyboard, mouse, joystick and paddle. More recent games make use of infrared beams from user's devices, the stylus from touch screen, or pressure-sensing pads to provide rich contextual sensing and interactions. In this paper, we propose the use of hand gestures as the basis for users to directly interact with game objects that are rendered across a flat plasma or LCD display. It forms a new paradigm of interaction in which the physical movements of hands in the form of hand gestures are coordinated along with the virtual objects in the game. Thus, the user effectively becomes an ldquoinput devicerdquo. We make use of a low-cost Web camera that is mounted over the gaming screen display to provide image-feed to the hand tracking and gesture recognition system, called Germane, which employs the hull-point analysis algorithm for gesture recognition. A working prototype of Germane has been developed to validate its operations on several common gestures. Performance evaluation results of Germane are also presented.

Abstract: Short series manufacturing forces production lines towards flexibility and reconfigurability with quickening pace. As many small- and medium enterprises wrestle to be profitable, the solutions are searched from modern manufacturing technologies like robotics. Currently, there are no commercially feasible OEM product packets available and therefore a lot of integration and development work is required before a production line is effective. To create such production lines in the future, this paper introduces a production platform concept ldquoIsles of Automationrdquo, which can provide the services that current systems are lacking. The Isles of Automation have a modular and layered structure, so the integration work will be easier and the robot cell will be as effective as it can be. To evaluate the concept, an example manufacturing process was selected and automated. The implementation mainly targeted the programming of the robot tasks, which is considered to be one of the main challenges with short series manufacturing robots.

Abstract: Introducing multi-agent (MA) technology into a remote control supervisory (RCS) system can improve the serviceability and enhance maintenance-free operation with the inter-terminal parameter (ITP) method. In addition, the system's distributed intelligent field terminals (IFTs) use a common algorithm that is unaffected by any changes to the system specifications. As a result of these innovations, the proposed system has much better serviceability because it is much easier to make modifications compared to that of conventional systems. This system has been implemented for practical purposes at over 60 sites.

Abstract: Nanocrystalline Diamond (NCD) is a very promising material for fabrication of high-temperature devices because of its unique mechanical and electrical properties. The prospective of using diamond is not only in sensors (MEMS) but in RF and power electronic as well. The strain gauges based on nanocrystalline diamond layers have been successfully designed and fabricated using mainly domestic technological background. The CoventorWare FEM calculations of the mechanical stress and geometrical deformations of a 3-D structure are used for a proper localization of the piezoresistor on the carrying substrate. The boron-doped piezoresistive sensing element was realized using a directed patterned growth of NCD film on SiO2/Si by microwave plasma enhanced chemical vapor deposition (CVD). Cantilever beam configuration was used for sensor characterization. The sheet resistance of tensometric layers as well as contact edge resistivity were measured by Transmission Line Method (TLM). The gauge factor of boron-doped NCD films was investigated in the range from room temperature up to 250degC and from 0 to 1 N of applied force.

Abstract: Solder joint shape measurement is one of the most challenging technique which is essential for automation of PCB inspection. It is difficult because the surface reflection is specular. Among several kinds of specular shape measurement techniques, deflectometry is suitable to measure the 3D profile of a specular free-form surface because of its high accuracy and short inspection time. In that a pattern displayed on a screen is reflected to be imaged on a image sensor. The surface shape is reconstructed from the distortion of the pattern. The major limitation of deflectometry is its limited measurable slope angle caused by the physical size of the screen. In this paper, we propose a multi-screen deflectometer to increase the measurable slope angle for solder joint measurement. And proper calibration method and shape reconstruction algorithm are developed. This idea is verified by experimental results, in which phase information is successfully extracted from the area which are not normally measurable due to its high curvature surface.

Abstract: The input/output characteristic curve of eddy current sensor is nonlinear. In order to ensure the linear relationship between the input and output, the compensation of eddy current sensor is very necessary. According to the non-linear problem caused by temperature and circuit interference during the detection process of the eddy current sensor, a nonlinear compensation method is proposed based on the support vector machine theory. The nonlinear characteristics of measured values of sensor are analyzed, and the support vector machine (SVM) inverse model is established while the displacement parameters as the output and voltage parameter as input. The effectiveness of SVM inverse model is verified by the simulation. Compared with the RBF neural network model, the SVM model is efficiency. The average absolute error of the model prediction is 0.0932 mm, so it has good linearity, and nonlinear compensation of eddy current sensor is realized.

Abstract: A tuning method for decentralized PI/PID with set-point weighting or 2DOF PI/PID controller is proposed in this paper. The tuning method is based on frequency domain analysis of a decentralized robust controller. In this method, desired dynamic equation (DDE) is designed firstly to meet the control specifications, and then the relation between desired dynamic equation parameters and controller parameters is given. The proposed tuning method is applied to a variety of 2 times 2, 3 times 3 and 4 times 4 models from literature and compared with the methods in references. Simulation results demonstrate that the proposed tuning method is of feasibility and effectiveness for multivariable processes. And because of its simplicity, the proposed method is applicable for the high dimensional ones. Besides, in this tuning method, each parameter has clear meaning and exact model expression is not indispensable, which makes it possible to apply the proposed method to practical industry.

Abstract: This paper presents an indirect adaptive stabilization scheme for first-order continuous-time systems under saturated input which is described by a sigmoidal function. The singularities are avoided through a modification scheme for the estimated plant parameter vector so that its associated Sylvester matrix is guaranteed to be non-singular and then the estimated plant model is controllable. The modification mechanism involves the use of a hysteresis switching function. An alternative hybrid scheme, whose estimated parameters are updated at sampling instants is also given to solve a similar adaptive stabilization problem. Such a scheme also uses hysteresis switching for modification of the parameter estimates so as to ensure the controllability of the estimated plant model.

Abstract: Semiconductor manufacturing is an industry with high cost. Improvement of production efficiency is always an important goal for manufacturers. Run-to-run control has been widely used in batch manufacturing processes to reduce variations. Threaded EWMA run-to-run control is an important stable control scheme. In this paper mixed products are manufactured in cycles. However, the process outputs will oscillate greatly in the first runs of every cycle if the disturbance follows IMA(1,1) series with deterministic linear drift and the break length of a certain product is large enough. A double EWMA controller is adopted to handle the disturbance and the drift. Furthermore, how to deal with process fault is also considered in this paper. Two kinds of fault - the step and ramp fault are discussed for fault tolerant approach which can reduce the large deviation of output from the target. Simulation study showed that the proposed approaches are effective.

Abstract: We address a neural oscillator based control scheme to achieve biologically inspired motion generation. In general, it is known that humans or animals exhibit novel adaptive behaviors regardless of their kinematic configurations against unexpected disturbances or environment changes. This is caused by the entrainment property of the neural oscillator which plays a key role to adapt their nervous system to the natural frequency of the interacted environments. Thus we focus on a self-adapting robot arm control to attain natural adaptive motions as a controller employing the neural oscillator. To demonstrate the excellence of entrainment, we implement the proposed control scheme to a single pendulum coupled with the neural oscillator in simulation and experiment. Then this work shows the performance of the robot arm coupled to neural oscillators in various tasks that the arm traces a trajectory. Exploiting the neural oscillator and its entrainment property, we experimentally verify an impressive capability of biologically inspired self-adaptation behaviors that enables the robot arm to make adaptive changes corresponding to an unexpected environmental variety.

Abstract: HEV-relay plays a significant role as a controlling switch which operates a gasoline engine and an electric motor by an electric controlling system of a hybrid electric vehicle (HEV). The relay has some problems in the operating process. First, the bounce of a moving contact by high speed impact makes unstable current flow because the relay completes an operating process only in a few milli-seconds. Second, it is difficult to design the actuating system to satisfy the desired design specification due to the complex design variables of HEV-relay. In this research, the electrical contact and springs consisted in HEV-relay are designed to improve bounce characteristics and to satisfy the desired design specification in the operating process. The shape of electrode is modified to reduce the bounce time in close process of HEV-relay. And the spring stiffness and initial compression force of each spring are optimized in order to satisfy the design specification such as operating time and velocity. The design procedures are based on the numerical simulation using LS-DYNA3D. The optimum performance of the HEV-relay is determined by response surface method (RSM) as the design methodology.

Abstract: This article sets to investigates and analyzes the snake-like robot by applying Lagrange method to establish the equations of motion. Based on equations of motion, the generalized coordinates are the absolute angles of bodies and center of mass of the snake robot. Friction force into the system is evaluated through the Coulomb model and the contact surface based on the rectangle shape. The elliptical friction model of Coulomb friction is considered; as this model allows more realistic result compared to viscous friction model. Although the robots relative angles are specified as a function of time, the robots equations of motion will be evaluated in a way that, the torque of actuators is not directly inserted into the equations, and the relative angles are the system inputs. Based on the serpenoid curve and parametric control through this curve, which influence the whole movement of the robot, the robot is controlled in such a way that it can travel the prescribed path. Accordingly, the robot can travel well through the prescribed curvilinear and or linear paths. By utilizing this method, the robot is navigated from a point outside the design path towards the defined path.

Abstract: We present a technique used for frontal collision warning in an intelligent vehicle. The system uses an image processing algorithm to detect taillights (red brake lights) of vehicles driving at night time. The area of red lights, the size of the largest brake lights, and the vehicle's speed are used to compute the rear-end collision risk, which can be used as an indicator to danger that potentially leads to frontal collision. Therefore, the driver can be warned, and he can perform brake action on time. The algorithm uses a threshold to detect red color on an RGB image. The thresholds are obtained from statistical collection of 50 sample images. From our experiment on real driving situation, the collision risk can predict the actual brakes with 90% accuracy. The result also indicates that the area of red lights detected has a close relationship with the brake applied.

Abstract: In order to research the anti-slip regulation (ASR) of electric vehicle(EV), this paper analyzes the operating principle and control strategy of electric vehicle's ASR, builds the motion model of the EV and vehicle dynamics model including the tyre, the wheel and the model between the tyre and the road. The traditional ASR structure is complex. In order to solve the problem, a novel anti-slip controller for EV without speed sensor is designed to prevent the slip between tyre and road. A back electromotive force (back-EMF) observer is constructed to acquire the information of speed as well as acceleration. By selecting the time constant or observer gain properly, the current command reduction characteristics can be adjusted freely in some range. The results of simulation and experiment verified the effectiveness of the proposed controller, which can prevent the driven wheels skidding, improve the traction performance, enhance the driving performance and the stability of EV, and avoid the occurrence of traffic accident. The anti-slip control for EV without speed sensor is an ideal anti-slip regulation method.

Abstract: In this paper we investigate an Intelligent Computer Vision System applied for recognition and classification of commercially available tiles from the cork industry. The system is capable of acquiring and processing gray images using several feature generation and analysis techniques. Its functionality includes image acquisition, feature recognition and extraction, data preprocessing (Analysis of Variance and Principal Component Analysis) and feature classification with neural networks (NN). The system is investigated in terms of statistical feature processing (number of features and dimensionality reduction techniques) and classifier design (NN architecture, topology, target coding, and complexity of training). We report system test and validation results of the recognition and classification tasks with up to 95% success rate. Some of those results are due to our investigation and combination of feature generation techniques: application of Analysis of Variance (ANOVA) and Principal Component Analysis (PCA), which appeared to be very efficient for preprocessing the data; and use of suitable NN design and learning method. The employed NNs are trained with our genetic low-discrepancy search method (GLPtauS) for global optimisation. The obtained and reported results demonstrate strongly competitive nature when compared with results from other authors investigating similar systems.

Abstract: Research on electrical load simulator (ELS) which is directly driven by permanent magnet synchronous motor (PMSM), and build up mathematical model of ELS. Analyze the couple relationship between torque motor and actuator, and the generating mechanism of extraneous torque in ELS, conclude that extraneous torque is directly related to the velocity of actuator, so propose velocity-loop compensation algorithm to eliminate extraneous torque of ELS. Aiming at requirement of high frequency response and kinds of nonlinear factors of ELS, the traditional PID control theory cannot meet the demand of control accuracy, so research on fuzzy control with non-uniform membership function, then combine fuzzy control and PID control with exponential function to avoid the sudden change of control output when switching between fuzzy and PID. And the results of experiments prove that ELS based on velocity-loop and improved fuzzy-PID has excellent performance.

Abstract: This paper presents a new technique of designing a direct digital controller for a single-phase pulse width modulation (PWM) converter system, based on closed-loop identification. It is difficult to analytically design a controller due to the double loop structure of the PWM converter control system. The design procedure consists of three steps. First, obtain a current controller for the inner loop system by using the error space approach, which is a powerful method for robust tracking control design. The outer loop is composed of a voltage controller, a current control loop including the current controller, a PWM converter, and a capacitor. Then, all the components, except the voltage controller, are identified by a discrete-time equivalent linear method, using the closed-loop output error (CLOE) method. Based on the equivalent model, a proper digital voltage controller is then directly designed. It is shown through PSim simulations and experimental results that the proposed method is useful for the practical design of PWM converter controllers.

Abstract: This paper proposes a new system configuration for a series hybrid power filter (SHPF) realized for all harmonic types of loads. The series hybrid filter consists of a small rated series active power filter (SAPF) and a shunt passive filter with variable inductance using a thyristor control reactor (TCR). The DC voltage available at the load side of a typical voltage harmonics source, such as a diode bridge rectifier followed by a capacitor, is utilized as a source of DC power for the SAPF. To increase the filtering performance of the shunt passive filter, SAPF is control in such a way that it increases the network impedance at the harmonic frequency. This also helps to avoid any series or parallel resonance that may occur. The shunt passive filter together with a TCR is used to support the variable load reactive power demand as well to tackle the current harmonics generated by non-linear load. The performance of proposed series hybrid power filter is validated through MATLAB/Simulink simulation study and successfully utilized to compensate the voltage sag, voltage swell, voltage harmonics, current harmonics and load reactive power demand.

Abstract: Fluid level monitoring is a common control task in chemical processes. The on-line level monitoring of fluids with different densities is a complex task to be accomplished using traditional sensors, as floats for example. Most of the classic sensors have parameters that need to be recalibrated several times when monitoring liquids with different densities. To accomplish the recalibration, the process must be frequently paused to suit the new liquid characteristics. Besides, some traditional level monitoring methods are not safe for use with flammable liquids. In this paper we propose a new density invariant and non contact approach for level monitoring that is based on image processing Hough transform and image normalization. A prototype was implemented and an experiment in laboratory was carried out to test the performance of the proposed model.

The focus of the proposed method is on the identification of the faulty current sensor in AC machines drives and the actual reconfiguration between two control-sampling times which ensures a safety continuous working of the faulty system. For performances verification, the method is analyzed within a FPGA-based real-time simulator (RTS) of the studied electrical system, based on criteria such as accuracy, execution speed and implementation complexity. For the RTS modeling process, a multi-sampling approach is adopted allowing a real-time functioning with different time-steps. ModelSim simulations and experimental results are presented to emphasize the effectiveness of the proposed method.

Abstract: This paper studies a fault-tolerant control system designed for a joint module of a light weight space robotic system. Considering the extremely tight constraints on small mass, low power consumption, low volume, stringent cost control, high system reliability, etc, the joint electronics is divided into two layers, central processing layer and peripheral interface layer, using different redundancy design on each layer.

Based on the results of the analysis, fault-tolerant mechanisms are proposed. The features of the hardware and software of the fault-tolerant control system are also presented. A prototype is developed, and performance is tested. With the results, the feasibility of the system design is verified.

Abstract: The displacement measurement in structural health monitoring (SHM), though important, was not popular due to inaccessibility and the huge size of the civil infrastructures. The frequently employed approaches use accelerometer, strain gauge, PZT, GPS, LVDT(Linear Variable Differential Transformer) etc., where most of them indirectly measure the displacement, require high cost, and are not so practical to install and maintain. Thus the development of SHM system that directly measures the displacement of the structure using low-cost sensors can be very helpful. In this paper, a multiple paired structured light (SL) system is proposed to be used as a structural displacement measurement. The proposed paired SL module is quite cheap to implement and can directly measure the accurate relative displacement between any two locations. Based on some simulations, a minimal configuration of the paired SL module is proposed. And the steepest descent and extended Kalman filtering-based displacement estimation methods are proposed by deriving a kinematic equation and its constraints. After building a prototype of the paired SL module, some real experiments are performed to test the feasibility of the system for the long-span structural displacement monitoring. The proposed system is expected to act also as a visual inspection and active sensing system if the mobility of the robot is utilized.

Abstract: We refer to channels of communication which link the user to various electronic appliances and computers as cognitive communication channels. One especially interesting research topic related to cognitive communication channels deals with a special application called sensory substitution, when information is conveyed through a channel other than the one that is normally used. Besides offering a glimpse of hope to those living with injured sensory organs, sensory substitution can have benefits when designing user interfaces in terms of cost-effectiveness, the reduction of network delays, as well as the prevention of channel overloading. One such application in robot control could be the substitution of haptic feedback gloves (which are costly, bulky and have relatively few vibration states) using parameter-rich audio interfaces. In this paper, we propose the foundations of a framework for user-directed, interactive experimentation with haptic feedback using auditory cognitive communication channels. Within the presented framework, the paper deals with an approach to describe the relationship between physical parameters and coding parameters that can be used to convey control information through auditory cognitive channels.

Abstract: This paper proposes a new robust load position servo system without mechanical vibration and end-effector offset for industrial robots. The compact high gear reduction without backlash, such as the harmonic gear is frequently used in the driving system for the sake of high load-to-weight performance. Generally, the industrial robots have used the sensors mounted to actuator-side because hardware setting using load side sensor is very hard to mount signal lines. Therefore, the end effector response does not perfectly reach the desired position owing to the effect of external disturbance force, which is called end effector offset. The proposed robust servo system uses the estimated load information due to repress the effect of external disturbance force. The proposed position servo system is designed based on the state & disturbance observer and robust speed control system using coprime factorization controller. The effectiveness of the proposed robust system is confirmed by experimental results of prototype mechanical system.

Abstract: As the number of electronic control units (ECUs) in vehicles increases, ECUs can create a large and complicated in-vehicle network. Therefore, in-vehicle networks need a network management algorithm for improved reliability. The open system and corresponding interfaces for automotive electronics/vehicle distributed executive (OSEK/VDX) set a goal of being the industry standard for real-time operating systems used in vehicle systems. OSEK/VDX includes a reliable network management algorithm, OSEK network management (OSEK NM). It has two types of management mechanisms: direct NM, and indirect NM. These have opposite characteristics and different management performance. This paper explains the effective factor of network management performance, and proves it using a real application experiment. Direct NM and indirect NM are implemented to controller area network (CAN), and performance is analyzed using real applications. The result of this paper contributes that as a case of network situation, application engineer selects two types of OSEK NM for the best performance.

Abstract: This paper presents the development and test of the standard IEC-60870-5 application layer protocol over TCP/IP for a remote terminal unit (RTU) based on open hardware and software. The RTU hardware is an embedded system, a SoC-type design using FPGA that has been programmed with the open core LEO/ with Linux operating system running over it, so both the and IOS are open source. For prototyping the GR-XC3S-hardware 1500 board has been used. There is no open source code available for the IEC standard protocols, so application layer protocol over TCP/IP has to be implemented. All the software design has been made in a PC platform using standard development tools. The source code generated for the protocol has been compiled with the standard Linux gcc compiler in LEON. Several tests have been made to prove that the RTU works correctly.

Abstract: Mobile phone manufacturing companies wish to use a software development platform based on Linux for application security and software development efficiency. The Linux platform development confers stability. The driver code for each device should be inserted in Linux kernel to run the hardware devices of the mobile phones. Applications must request device control from the driver kernel using a specified access interface. In these structures, the stability of the mobile phone system depends on the developer's skill. Therefore, developers must make appropriate use of the driver code to be activated in the Linux kernel. They should design the programming interface to be reliable, correct and robust, so applications can be easily ported. Therefore, we ported the device driver code from the Linux kernel to the user area. We designed a driver framework based on the D-bus in user area. Most of driver code in the user area and application can access the device passing D-bus interface the driver framework offers. Therefore, we could improve system stability.

Abstract: This paper gives a hardware-efficient algorithm and VLSI architecture for finding a path for a robot on an environment image. The algorithm constructs a distance map to identify the collision-free region for a given robot and then finds a path on the region. The path obtained from a start to a goal is the shortest path in terms of the number of steps. The time-critical part of the algorithm is mapped on to a two-dimensional cellular architecture that consists of a locally interconnected array of identical processing elements. Due to this local interconnection and regular structure, the architecture can be operated at a high speed and is easily scalable. The design has been implemented on the XCV8000 device of Xilinx. The maximum frequency of operation obtained is 246 MHz. This leads to computing a collision-free path on images of size 100 times 100 in less than 41 mus. The hardware is capable of processing images at a video rate for real-time path planning in a dynamic environment.

Abstract: We measured synchronization performance of FlexRay for OSEKtime and described why we must consider synchronization performance. Previous studies present scheduling methods for time-triggered systems when ideal constraints WCET(Worst Case Execution Time), deadline, resource dependency, etc.) are given. However, there are some differences between real distributed systems and ideal constraints. Because the scheduling method of OSEKtime is based on a clock that is synchronized via a communication protocol such as CAN (controller area network) and FlexRay, synchronization performance influences the scheduling result. Therefore, we measured the synchronization performance of FlexRay and described why we must consider synchronization performance for OSEKtime scheduling.

Abstract: We present a noble encoding method for designing an optimal fuzzy classifier with evolutionary optimization. Evolutionary designs of fuzzy classifiers is divided into design of fuzzy rules and design of fuzzy membership functions. Among these design problems, for an evolutionary design of membership functions, the shapes of each membership function are mainly considered in the previous related works. In other words, design of fuzzy membership functions is formulated as a parameter search problem for tuning the shapes of each function (e.g. center(or mean) and width(or variance) in a Gaussian function). In this paper, we newly consider the design of fuzzy membership functions as optimization of intersection positions between adjacent membership functions. According to recent insightful researches, classification boundaries are determined by the points of intersection of membership functions. Therefore, the proposed approach differs from conventional approaches in that the proposed method can search and manipulate the border of classification which directly influences the classification performance. In order to verify the proposed encoding method, simulation study is carried out. For this simulation study, we apply the proposed encoding scheme to the basic genetic algorithm (GA), one of the most widely used evolutionary optimization methods in the recent literatures. The performance of the proposed method is investigated with two real world databases, dasiairispsila and dasiaglasspsila data.

Abstract: An adaptive control for robot manipulators based on multiple incremental fuzzy neural networks (FNNs) is proposed in this paper. The overall controller is comprised of a feedback controller and multiple FNNs which learn inverse dynamics of the robot manipulator for different tasks. The multiple FNNs are switched or blended to improve the transient response when manipulating objects are changed. The structure and parameters of the FNNs are determined dynamically using an incremental learning algorithm which reduces complexity and computation induced by the use of multiple models considerably. The parameters are refined online to compensate for uncertainties. The closed-loop system with a switching or blending law is proven to be stable in Lyapunov sense. The proposed scheme is applied to control a two-link robot manipulator with varying payloads.

Abstract: In this paper, a new PWM technique for induction motor drives involving six concentric dodecagonal space vector structures is proposed. Apart from increasing the linear modulation range compared to a hexagonal space vector structure, the proposed configuration helps in total elimination of 5th and 7th order harmonics from the phase voltage throughout the modulation range. Thus, it is possible to operate the inverters at a reduced switching frequency without compromising on the quality of output sinusoidal voltage being fabricated. The space vector structure is realized by feeding an open-end induction motor drive from two three-level inverters having isolated asymmetric DC link voltages. Simulation and experimental results presented in this paper show the applicability and usefulness of the concept for high power drives.

Abstract: In this paper, authors presents a novel competitive multilevel converter. The novel cascaded U cells topology is constituted from two power switches and one capacitor for each cell. In case of DC/AC conversion, the proposed fifteen level inverter allows a nearly sinusoidal output voltage resulting on a perfectly sinusoidal load current. In case of AC/DC conversion, the proposed fifteen level rectifier presents a reduced impact on the utility supply, a good energetic efficiency and a small number of power switches and passive components. An average model of the proposed converter is performed and a control strategy is designed in order to draw a nearly sinusoidal current and voltage. Active and passive filters can thus be avoided resulting on a highest energetic efficiency and a reduced installation cost. The proposed converter presents also the possibility and the simplicity of changing the number of voltage levels only by acting online on the ratios of the desired output voltages. The modeling and control strategy of the proposed fifteen level converter were verified by simulation.

Abstract: Different techniques for the asymmetries in the rotor of asynchronous machines in closed-loop controlled drives have been developed; they usually need to monitor currents and speed. This paper investigates the detection of rotor asymmetries in field oriented controlled induction machines based only on the measured currents and without the measurement of the speed. The paper uses the indicator for asymmetries in the rotor of induction machines that was proposed in an earlier paper and extends it to the case of sensorless control schemes. The main focus of the paper is not in the sensorless control at low speed and supposes therefore that a simple model based on the voltage equation of the machine is sufficient. The region of low operation frequencies represents therefore no problem for the detection procedure. Laboratory measurements corroborate developed algorithm.

Abstract: The speed of the rotor and the speed of the rotating magnetic field are different for induction machines. The difference is described by the slip which is normally unknown because it depends on the load. For motion control the speed must be known. This information is mostly taken by a separate rpm sensor. It is desirable to eliminate this sensor because the availability of the machine will be higher, working processes under demanding ambient conditions are easier feasible and the investment for the sensor will be saved, too. This paper explains the basic principle of a sensorless speed measurement which uses anisotropies to detect the rotor speed. Additionally a mathematical model describing the behaviour of the modified machine is presented.

Abstract: This paper presents a new control strategy that allow the photovoltaic system operate under grid faults without overpass the rated current and assuring sinusoidal currents. In the classic control strategies used in photovoltaic systems the power delivered to the grid remains constant when a fault occurs, hence the current can reach dangerous values. Therefore the converter has a protection system to disconnect it avoiding its damage. Thus it must be connected manually when the electrical grid is re-established. The strategy presented here overcomes these drawbacks. It is compared with the classic strategy through simulations in PSCAD and the experimental results prove its effectiveness.

Abstract: Recently, renewable energy such as wind turbine generator and photovoltaic system are introduced as distributed generators (DGs). Connection of a large amount of distributed generator causes voltage deviation beyond the statutory range in distribution system. Reactive power control of inverter interfaced with DG is one of the solutions against this problem. Additionally, reactive power control has a possibility to contribute for reduction of distribution loss. In this paper, we propose a voltage control method in distribution system by reactive power control of inverters interfaced with DGs. The proposed method has been developed with the aim of reduction of distribution loss and voltage regulation into statutory range without any telecommunications. In the proposed method, each interfaced inverter controls reactive power based on voltage control reference, which is calculated from local measurements. The calculation rule of control reference has been developed using optimal data, which consist of relations between ramdomly given inputs and corresponding optimal outputs calculated by an optimization technique. Simulations are conducted to show the effectiveness of the proposed method.

Abstract: This paper describes a novel approach for the photon shot noise reduction in an image sensor inspired from an M-transform method. In our proposed method, the photon shot noise is converted into small amplitude signals. Then, the signals are treated to remove the small amplitude noise by an epsiv filter. The Sobel method is applied to the edge detection. The edge of the object is protected by not treating the epsiv filter into the detect edge. After removal of the noise, the data of M-transform are restored to the image by a reverse M-transform. The proposed method is compared with the smoothing filter, the median filter and the Wiener filter. In cases where the number of the maximum incidence photons was 256 pieces (illumination is about 4 lx), the proposal technique indicated the PSNR (Peak-Signal to Noise Ratio) value better than the Wiener filter. Moreover, also with the low illumination less than 4 lx, the edge is maintained and the proposal technique is judged to be excellent in comprehensive evaluation.

Abstract: In this paper, we propose both IIR-based and FIR-based all-pass filters based on the minimax criterion.

As a result, one example of numerical design is shown to verify the proposed method. In addition, the FIR-based phase equalizer for reducing the phase distortion caused by rational filter banks is also addressed to demonstrate the usefulness of our approach.

Abstract: We propose a new method for 1/f noise reduction in complementary metal oxide semiconductor image sensors (CMOS Image Sensors: CIS) by applying characteristics of noise distribution on time domain. The algorithm using time domain or stacking images which are focused on same pixel position are proposed to make up for the weakness of general method on edge region. Nevertheless, in the case of using of self-pixel position, some problems such as blocking effect or acquisition of images are occurred. In this study, we propose the algorithm 3D weighted filtering using multi-images through noise distribution. By using weight value on the center pixel of each 2D masks, the optimized algorithm is implemented. The purpose of proposed method is to obtain the best PSNR with minimum number of frame and minimum weight value. We have used White Gaussian noise distribution because 1/f noise has that distribution. Through the proposed algorithm, we have obtained the better PSNR than other methods as a masking method, Wiener filter and self pixel based method. The algorithm is expected that is effective for other random noise likes as photon shot noise with Poisson distribution.

Abstract: We introduce the adaptive speckle reducing anisotropic diffusion(SRAD) that uses wavelet for enhancement of medical ultrasound images. This method first modifies coarse-to-fine classification to decide the homogeneous region that operated as diffusion threshold in SRAD works. Then, SRAD are played on each scale of decomposed wavelet domain with determined homogeneous regions as called ldquospeckle scale functionrdquo. From this process, homogenous region can considered without manual selection or preliminary exponential decay function. As a result, conventional SRAD will modify as adaptive one. Moreover, variety pattern of speckle is reduced by the proposed modified SRAD on wavelet decomposing. The proposed method can improve the image quality for ultrasound images enhancement. Finally, we validate this method to compare with conventional filters group using artificial speckle image and real ultrasound images. The experimental results show that the proposed method performed effectively both terms of speckle reduction and edge preservation.

Abstract: This paper presents a sliding mode controller to compensate the friction of mini voice-coil motor (VCM), embedded with guide pins, for position control in compact camera module (CCM) application. In the VCM, actuator full stroke is only 0.35 mm or less, nonlinear friction force falls into mismatched condition and um-level resolution is required. With proposed controller, arbitrarily small steady state error can be approached by pole placement of the sliding mode state equation. The performance is firstly simulated with a physical VCM model. The experimental result is then presented to demonstrate the proposed controller is able to avoid stick-slip oscillation that usually yields when using classic controller, such as PI controller.

Abstract: In recent years, there has been much research in the development of ultra-precision control technology for automated machine tools to meet the increasingly stringent tolerance requirements. Minor disturbances in input torque, such as torque ripple and static friction that can normally be neglected, become apparent at micron-level scale. We propose a novel form of sliding mode control (SMC) to compensate for static friction and torque ripple in direct drive motor (DDM). A conventional SMC uses a sign function to drive the error on to the sliding surface, while our improved SMC uses the integral of the sign function to achieve the same purpose. Coupled with an exponential reaching law, this new algorithm can better suppress disturbance torque and chatter. This paper presents the derivation of our modified SMC algorithm. Simulation results demonstrate its robustness against disturbances and fitness for use in ultra-precision DDM.

Abstract: Ship fin stabilizer is widely employed in reducing rolling motion. But the effectiveness of ship fin stabilizer can be severely deteriorated due to the nonlinear and uncertainty arising from ship parameter variations, unsteady hydrodynamic characteristics, and waves. Variable structure control can offer several desirable characteristics, such as fast dynamic response, insensitivity to parameter variations, and rejection to external disturbances. However, common variable structure controllers require not only the bound value of uncertainty be known in advance but also the existence of chattering, especially to discrete system. The grey prediction method requires only a few sampled data to develop the grey model and to forecast on future. In this paper, an improved reaching law and an improved grey prediction method are employed to enhance performance and reduce chattering.

Abstract: In this paper, we propose a hierarchical terminal sliding mode control approach for nonlinear underactuated systems which can drive the error to zero in a finite time. Here, the controller has the double layer structure because the system is divided into two hierarchical subsystems. In the first layer, the terminal sliding surfaces are hierarchically designed for each subsystem, and in the second layer, the whole sliding surface is designed as the linear combination of terminal sliding surfaces. The asymptotic stability of the system is verified by Lyapunov analysis because the controller is based on terminal sliding surface. Finally, we carry out simulation on a representative underactuated systems such as the overhead crane system, to illustrate the effectiveness of the proposed control scheme.

Simulation results have shown that the proposed control method provides very good path tracking with the balance error kept within very small boundaries.

The key idea of this method was obtained from the usual way of dividing an indoor environment into sub-regions, i.e., rooms based on the identification of doors. The proposed virtual door algorithm extracts the virtual doors by overlapping a Generalized Voronoi Diagram (GVD) and a configuration space eroded by the half of the door size. The region to region cleaning algorithm is also proposed based on the closing and opening of virtual doors. The performance of our algorithm has been tested on various real indoor environments using a commercially available cleaning robot.

Abstract: It is very important to communicate between the many electronic components in automobiles. If any component has an error, is possible for the error to affect other components. We propose a method of handling cyclic redundancy check (CRC) errors in the network using FlexRay. The FlexRay vehicle network protocol features fault-tolerance and guaranteed message latency. According to the FlexRay specification, each node in the FlexRay network decodes received messages and checks for various errors. However, if error occurs to any node, other nodes on the network do not know that a particular node generated an error. In this case, the node that did not receive the critical message cannot be guaranteed to demonstrate correct behavior. In order to solve this problem, we suggest a solution using dynamic messages supported by the FlexRay protocol.

Abstract: This paper considers the consensus problem of continuous-time sensor network in a noisy environment, in which both fixed topology case and switching topology case are considered. The main idea is based on the fact that the state of each agent has twofold identity, i.e., the state of itself and the control input of agents that take it as a neighbor. With this in mind, we first solely design unbiased Kalman filters for each agent such that the sensor network solves consensus problem when all information is contaminated by noises. Then, the convergence of the proposed algorithms is proved. All the proposed algorithms are fully distributed, unbiased, and use the least information. The validity of them is illustrated by the included numerical examples.

Abstract: When implementing a mathematical function in h/w, we would like to minimize the required resources. This task is critical in FPGA designs. One of the popular techniques for implementing mathematical functions in h/w, is a lookup table (LUT) based design. In order to reduce the required memory size, the common implementations use a pre-defined set of input values for which the function values are stored in a LUT, and apply a linear or 2nd order interpolation between these values. In this paper we design an efficient FPGA implementation of a 10y conversion circuit using this approach. We suggest a simple scaling approach based on the mathematical properties of the 10y function that allows a more efficient implementation compared to a circuit based on the conventional approach without scaling. We then demonstrate the implementation of this approach in a FPGA.

Abstract: Intelligent industrial robots must respond rapidly to environmental stimuli, and therefore the integration and real-time processing of motion-vision functions are of utmost importance. Robot decision making and motion control are commonly based on visual information in industrial machine vision applications.

In this paper, we propose a new embedded system that performs motion-vision functions in real-time using a dedicated, integrated processor. By employing both conventional and a dedicated processor, we were able to design a motion-vision integrated system that is both efficient and versatile.

Finally the images are rendered with their parameters to a spherical surface, where the linear blending and bi-linear interpolation are employed to render the images. The spherical surface is unfolded into a planar surface which gives the final mosaic result.

Abstract: This paper studies the effects of voltage sags (dips), both symmetrical and unsymmetrical, on the three-phase synchronous machine (SM). The vast majority of the electrical power generation systems in the world is consist of synchronous generators coupled to the electrical network though a transformer. Voltage sags on SM cause speed variations, current and torque peaks and hence may cause tripping and equipment damage. The consequences of voltage sags in the machine behaviour depends on different factors such as its magnitude (or depth), duration and initial point-on-wave, and also on the parameters of the machine. In this study, three machines of different nominal power have been used for simulate on MATLAB the effects of the voltage sags on the machine under specific conditions.

Abstract: The aim of this work is to analyze a typical configuration of a wind turbine generator system (WTGS) equipped with a variable speed generator. Nowadays, doubly-fed induction generators are being widely used on WTGS, although synchronous generators are being extensively utilized too. There are different types of synchronous generators, but the multi-pole permanent magnet synchronous generator (PMSG) is chosen in order to obtain its model. It offers better performance due to higher efficiency and less maintenance since it does not have rotor current and can be used without a gearbox, which also implies a reduction of the weight of the nacelle and a reduction of costs. Apart from the generator, the analyzed WTGS consists of another three parts: wind speed, wind turbine and drive train. These elements have been modeled and the equations that explain their behavior have been introduced. What is more, the whole WTGS has been implemented in MATLAB/Simulink interface. Moreover, the concept of the maximum power point tracking (MPPT) has been presented in terms of the adjustment of the generator rotor speed according to instantaneous wind speed.

Abstract: Recently, dispersed generators have been installed in distribution network to supply power to commercial facilities. Renewable energy generation contains output power fluctuations and distributed generator produces sluggish response for power demand.

Abstract: Ultrasound image segmentation is challenging due to the interference from speckle noise and fuzziness of boundaries. In this paper, we propose a segmentation scheme using fuzzy c-means (FCM) clustering incorporating spatial information based on intensity and texture of images. Firstly, the nonlinear structure tensor, which helps to refine the edges detected by intensity, is used to extract speckle texture. And then, a spatial FCM clustering method is applied on the image feature space for segmentation. In the experiments with simulated and clinical ultrasound images, the proposed method can get more accurate results than the conventional FCM and other segmentation methods.

Abstract: This paper is concerned with distributed receding horizon prediction for continuous-time linear stochastic systems with multiple sensors. A distributed fusion with the weighted sum structure is applied to the optimal local receding horizon predictors. The distributed prediction algorithm represents the optimal linear fusion by weighting matrices under the minimum mean square criterion. The algorithm has the parallel structure and allows parallel processing of observations making it reliable since the rest faultless sensors can continue to the fusion estimation if some sensors occur faulty. The derivation of equations for error cross-covariances between the local predictors is the key of this paper. Example demonstrates effectiveness of the distributed receding horizon predictor.

Abstract: In ECG based medical interpretation systems, the knowledge of the cardiac signal propagation, corresponding muscle potential and respective spatial distribution is of great importance. In this paper we have converted the real-valued ECG signals into complex-valued signals using Hilbert Transform and obtained the continuous wavelet transform (CWT) of this signal. The time localizations and energy centers in the CWT can be used to predict the basic origin of the signal, unlike in real-valued correlation techniques. The concepts derived from this method are used in identification of the possible origins of the signals in the heart, through an inverse system identification procedure. The results show that this would be a potential tool for interpreting ECG based diagnosis.

Abstract: How to retrieve cloud images from a large cloud image collection becomes an emergent and challenging problem in meteorological area because of the fast accumulation of digital cloud images and the need of cloud automatic observation. This paper aims to address the problem of cloud image retrieval (CIR), which will promote the intelligence of sky imager instruments and help the researchers of meteorology to index and retrieve cloud image. We put forward the keypoint based moment invariants (KeBaMI) descriptor in the framework of CIR. KeBaMI depicts the cloud shape feature with statistical moment invariants based on keypoint, rather than on boundary in traditional approach. Furthermore, we implement the prototype of CIR with KeBaMI. Our experiment results show that KeBaMI is significantly superior over traditional edge based moment invariants descriptor.

Experimental results show that the proposed algorithm has a higher precision and is more suitable than the baseline method for real-time rail head surface defect detection application.

Abstract: Gray-level clustering is an important procedure in image processing, which reduces the gray-level of an image. In order to display an image with high gray level in a screen with lower gray level, a good gray-level clustering algorithm is necessary to complete this job. Based on the mean value and standard deviation of histogram within a sub-interval, a novel recursive algorithm for solving the gray-level reduction is proposed in this paper. It divides the sub-interval recursively until the difference between original image and clustered image within a given threshold. Experiments are carried out for some samples with high gray level to demonstrate the computational advantage of the proposed method.

Abstract: In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame synchronization is an essential procedure for normal operation of the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation. In order to enhance the frame synchronization and frequency offset compensation performances, we add a ternary sequence to OFDM signals in the time domain. The power level of the ternary sequence to be added needs to be low enough in order not to affect a normal operation of the OFDM system. The objective can be achieved successfully based on the correlation characteristics of the ternary sequence.

Abstract: Detection of single-phase-to-ground fault is a difficult task in power distribution network, especially in the Peterson-coil-grounded system, as the fault current is too small to be evaluated and the noise make it be difficult to extract the fault signal. In this paper, an improved hybrid filter (IHF) based on mathematical morphology (MM) is proposed to detect the faulty feeder in single-phase-to-ground network. Comparison studies with other MM-based filters show that the IHF has best performance of noise elimination. After the zero-sequence fault current is processed using IHF, the faulty feeder is detected by using the criterion of amplitude and phase. The proposed IHF can avoid the wave shift efficiently and is also good at removing the noise. The simulation results validate the merits and the effectiveness of the scheme.

Abstract: In this paper, we analyze and simulate the iterative decoding performance of space time block coded (STBC) pulse position modulation-time hopping (PPM-TH) ultra-wideband (UWB) systems in indoor environments. The indoor wireless channel is modeled as a modified Saleh and Valenzuela (SV) channel, which is proposed as a UWB indoor channel model by IEEE 802.15.SG3a. In order to reduce the iterative decoding complexity, Max-Log-MAP algorithm is employed. The performance is evaluated in terms of bit error probability (BEP). From simulation results, it is shown that the double binary turbo coding scheme offers considerable coding gain compared with an uncoded system according as the number of iterations increases.

Abstract: Speech enhancement is very important in the application of speech recognition and communication. To implement it, a FFT-based dual-ALU processor by using hardware-software codesign is proposed in this paper. For the consideration of computation load, the speech enhancement adopts spectral subtraction method to reduce the influence of noise. In this case, FFT occupies most of the computation load. To reduce the computation load and power consumption, we proposed radix-2 pipeline FFT architecture. Based on this FFT, the spectrum analysis can be efficiently applied. Then we proposed a dual-ALU processor to implement the spectral subtraction. This dual-ALU architecture can provide parallel calculation capability. Besides, the area of the second ALU is only half of the first ALU. The design has been fabricated in the total area of 2.82 mm times 2.82 mm by using TSMC 0.13 mum 1P8M CMOS technology.

Abstract: An interleaved zero voltage switching (ZVS) converter with less component count and boost voltage conversion ratio is presented. The output voltage doubler is used on the output side to achieve the boost type of voltage conversion ratio. The proposed converter includes two active-clamping converters with common clamp capacitor to share load current. By the shared capacitor, the charge balance of two interleaved parts is automatically regulated under input voltage and load variations. The ZVS turn-on of all switching devices is achieved during the transition interval. The interleaved pulse-width modulation (PWM) operation will reduce the ripple current and the size of the output capacitor. The proposed circuit has no large output inductor such that the adopted circuit has simpler structure, lower cost and no effective duty loss. The voltage stresses on output diodes are clamped at the output voltage. The circuit configuration, operation principles and design consideration are presented. Finally experimental results based on a 425 W (170 V/2.5 A) prototype are provided to verify the effectiveness of the proposed converter.

Abstract: This paper presents a high performance switched reluctance motor (SRM) drive based on dynamic observer. The dynamic observer estimates the rotor position and speed for wide speed range. As well, observer gains online will be corrected by using fuzzy logic hybrid algorithm (FLHA) with concern of estimation errors. In addition, a fuzzy logic current compensator (FLCC) for reducing torque ripple has been presented. In the regions that torque reduces, the FLCC, inject additional current for each phase currents.

Simulation results show that proposed drive will estimate the rotor position and speed with high precision for all speeds (near zero speeds up to rated speed). Also, FLCC minimize the torque ripple and reduce speed estimation error, too. This drive has the advantages of robustness, high reliability and excellent performance at steady state.

Abstract: This paper describes a design of a cascaded H-bridge converter for insulation testing of the crosslinked polyethylene (XLPE) cable. This high voltage generator produces a sinusoidal waveform at a very low frequency (VLF) of 0.1 Hz. The design of the cascaded H-bridge converter consists of two main parts, a modulation unit and a switching unit. The modulation unit compares the 0.1 Hz reference sinusoidal waveform with the 10 kHz of carrier waveform. The switching unit consists of 6 H-bridge modules using phase disposition (PD) multicarrier modulation scheme to generate 13 levels of PWM signals. The cascaded H-bridge converter can covert the high voltage direct current (HVDC) to multilevel step-pulse signals and change to the sinusoidal waveform at 0.1 Hz by the low-pass filter. The use of multilevel H-bridge converter helps reduce the total harmonic distortion (THD) from single level H-bridge converters. The experimental results show that the THD value is less than 5% complied to the IEEE 400.2 standards.

Abstract: This paper presents analysis of inverse kepstrum (known elsewhere as complex cepstrum) and its application technique to two-microphone adaptive noise canceling structure. It is based on identification of one acoustic path transfer function from the ratio of two acoustic transfer functions and the estimator results are implemented in an innovations-based form. The method uses that the front-end inverse kepstrum estimates a denominator polynomial from the ratio of two acoustic path transfer functions between two microphones and then the cascaded adaptive FIR filter estimates the remaining numerator polynomial. It is applied to conventional adaptive noise canceling structure to achieve an improved performance in noise cancellation with an efficient processing technique. As a result, it will be shown that the front-end inverse kepstrum gives rise to computational simplicity, therefore could be applied to any noise cancelling method in a real-time processing.

Abstract: This paper presents the compensation filter design for the two-stage CIC decimation filter. The goal is twofold: to avoid the integrator section at high input rate and obtain a low wideband passband droop of the overall filter. To this end the decimation is split into two stages with the cascaded less order RRS filters at each stage. The first stage can be implemented either in non recursive form or using the polyphase decomposition. The simple compensation filter and the sharpening are applied to the second section where RRS filter is implemented as a CIC filter. The resulting structure is a multiplierless and with no integrators at high input rate. Additionally, the structure exhibits a low passband droop and a high stopband attenuation.

Abstract: In this paper, a 3D leaf position measurement method based on stereo vision is proposed for guidance of an autonomous spray robot. A binocular stereo vision system is constructed by a single camera, which can move up and down on the vertical arm of the robot. With this vision system, a disparity map that contains the depth information of the plant leaves are calculated from the acquired image pairs firstly. Disparity map is a mid-step of 3D reconstruction and describes the relative changing depth and contour of the object surface. After processing the disparity map, leaves are segmented and their depth regarding local camera coordinates could be measured. However, camera coordinates does not provide complete 3D information for autonomous spray. The measured results from the local camera coordinates were further converted to the robot coordinates that are uniform for the robot control. The experimental data carried out with simple-shaped leaves were evaluated with the results from the proposed method.

Abstract: This paper describes a hardware oriented algorithm for eigenface based face detection using FFT. Eigenfaces have long been used for face detection and recognition and are known to give reasonably good results. But, the distance from face space is not a completely reliable measure to detect faces. We have derived the FFT-based computation of distance measure which facilitates hardware implementation and fast face detection. We have also extended the face detection framework by training with the whole face as well as other facial features like eyes, mouth etc. separately. The basis eigen vectors are obtained for face features and by combining the distance measure obtained in each case separately, better classification is obtained.

Abstract: This paper proposes a new method of pest detection and positioning based on binocular stereo to get the location information of pest, which is used for guiding the robot to spray the pesticides automatically. The production of agricultural cultivation in greenhouse requires of big quantities of pesticides for pest control. Pesticides application is a major component of plant production costs in greenhouse, and the excess in their applications have a great negative impact on the environment. A pesticide application is ideal if the spraying coverage is presented as evenly distributed over the whole plant canopy and, if the product application is correctly adjusted for minimizing the losses towards the soil or the environment. In this approach, the difference of color features between pest and plant leaves is extracted by the image segmentation to identify pest. According to the results of image segmentation and binocular stereo vision technique, the 3D position of the pest has been obtained. In the process of position locating, centroid-matching technique is adopted to displace the common object-matching. The formula based on binocular stereo vision to measure distance is revised, additionally.

Abstract: The paper described a structure of three modules diagnosis system for detecting and identifying faults that occur in the sensor and actuator of control systems with input and output signals related to the component itself. The diagnosis algorithm consists of three steps; firstly, generalized morphological filter with multi-structure elements is designed to filter the random noise and impulse noise in sensor's and actuator's input and output signals. And secondly, wavelet transform, which has been proposed for sensor's fault diagnosis some years ago, is developed for control system (sensor and actuator). To effectively extract the abruptly fault characteristic, a wavelet transform was used to analyze the filtered signals in this paper. By the multi resolution analyzing (MRA), the faults can be detected accurately. Thirdly, according to calculating the Lipschitz exponent (LE) at the fault's point, the fault type can be identified. The super-heated temperature control system has been studied. The effectiveness of the proposed approach is demonstrated by the means of experimental results and simulations.

Abstract: The decentralized collaborative target tracking problem in wireless sensor network (WSN) is investigated in the fusion of quantized innovations perspective. A hierarchical fusion structure with feedback from the fusion center (FC) to each deployed sensor is proposed for tracking a target with nonlinear Gaussian dynamics. Probabilistic quantization strategy is employed in the local sensor node to quantize the innovation. After the FC received the quantized innovations, it estimates the state of the target using the sigma-point kalman filtering (SPKF). To attack the energy/power source and communication bandwidth constraints, we consider the tradeoff between the communication energy and the global tracking accuracy. A closed-form solution to the optimization problem for bandwidth scheduling is given, where the total energy consumption measure is minimized subject to a constraint on the covariance of the quantization noises. Simulation results illustrate that the proposed scheme obtains average percentage of communication energy saving up to 40.8% compared with the uniform quantization, while keeping tracking accuracy very closely to the clairvoyant SPKF even when the latter relies on analog-amplitude measurements.

Abstract: The interference cancellation ratio (ICR) is influenced by the zero offsets of the devices in the weight branches. The gains in weight branches are moved to error feedback loop to guarantee ICR without influencing the convergence speed. The limiter is used to protect the multipliers thus the system becomes a nonlinear system. Through the describing function method and simulation, the stability, dynamic characteristics and steady-state characteristics are analyzed. With limiter, the stability of the system is uninfluenced. The steady-state characteristics are related with the parameters of limiter, the gain, the time constant of the low-pass and the amplitude of the signal. The convergence speed will decrease under the conditions of under damping and critical damping. If system is over-damped, the initial gain determines the growth of convergence speed. In this paper, a criterion to judge whether steady-state characteristics varies and the proper rule to increase the convergence speed with over damping are obtained.

Abstract: The tightly-coupled GPS/SINS integrated navigation system based on the adaptive multi-sensor track fusion algorithm utilizes the adaptive track fusion algorithm to fuse the output of the GPS/SINS Kalman filter and GPS Kalman filter. In case the GPS outages occur, accuracy of the system will be degraded rapidly due to the lack of measurements of the two Kalman filters. An algorithm of bridging GPS outages using radial basis function neural network is presented to improve accuracy of the navigation system during the GPS outages. This method uses radial basis function neural network to predict measurement of GPS/SINS Kalman filter during GPS outages in order to ensure the regular operation of the filter, resulting in reliable performance of the system. The performance of the method proposed is examined using intentionally introduced GPS outages and the mathematic simulation results have shown that the method proposed outperforms the navigation system without the neural network.

Abstract: Formulating the suitable mathematical models and deriving the efficient algorithms are very crucial for simplifying the complexity of the kinematics problems in robotics. Forward and inverse kinematics of industrial robot manipulators is generally performed using Denevit and Hartenberg method. In this paper, the algebra based on the exponential rotational matrices is used as an alternative method for driving the direct and inverse kinematics of the 6-DOF industrial robot manipulators with Euler wrist. The main advantage of this method arises from the explicit physical interpretation of the mechanism without deriving DH table. The exponential rotational matrices can also be easily implemented in the programming of robot manipulators. The RS and NS robot manipulators are given as examples to demonstrate the effectiveness of the employed method.

Abstract: This paper addresses stable haptic interaction for AFM (atomic force microscope)-based nanomanipulation. The EBA (energy-bounding algorithm), a passivity-based haptic control algorithm, is modified to include the scaling factors in the scaled bilateral teleoperation, and a commercial AFM is revised to be used as a nanomanipulation system with a 1-DOF custom-built haptic interface. Preliminary experiments show that the modified EBA can maintain stability during the interaction between an AFM probe and the surface of a sample for any force scaling factors.

Abstract: This paper suggests two advantages of the biarticular muscle which has been said to play an important role in human's motion control; one is stiffness direction stabilization of an end effector which results in stabilization of the posture, and the other is inertia matrix diagonalization in the dynamics of a robot manipulator. In order to analyze these characteristics, we adopt three-pair six-muscle model of human arm including biarticular muscles and derive simple relationship between an endpoint force/position and three muscle torques based on the absolute angle of two joints. Based on the derived equation, the relationship between the stiffness in the workspace and in the muscle torque space is calculated and the direction of stiffness that can be enhanced by the biarticular muscle is revealed. Finally, we suggest a new dynamics of the planar robot manipulator with three muscle torque input where the inertia matrix is diagonalized.

Abstract: This paper proposes an underactuated hand with passive adaptation. Although a passively adaptable hand can grasp an object reliably, most hands with passive adaptation can perform only the power grip due to their power transmitting mechanism. In real applications, however, various poses for grasping are necessary and an active control of fingers with motors should be performed in some cases. To cope with these limitations a 4-DOFs(degree of freedoms) hand with passive adaptation was developed. A wire-pulley mechanism was adopted to enable the passive adaptation and was verified with a 1-DOF hand. To enable both power and pinch grip two wire-pulley transmissions are equipped at the palm. Balancing motion is enabled by rotating the thumb in the normal direction to the palm. The hand can be spread out to grasp a large object. Various experiments have shown that reliable grasping can be obtained with the proposed hand.

Abstract: Hand motion tracking and gesture recognition are a fundamental technology in the field of proactive computing for a better human computer interaction system. In this paper, we have developed a 3-D hand motion tracking and gesture recognition system via a data glove (namely the KHU-1 data glove consisting of three tri-axis accelerometer sensors, one controller, and one Bluetooth). The KHU-1 data glove is capable of transmitting hand motion signals to a PC through wireless communication via Bluetooth.

Abstract: We addresses the issue of expressive face modeling using an advanced active appearance model for facial emotion recognition. We consider the six universal emotional categories that are defined by Ekman. In human face, emotions are most widely represented with eyes and mouth expression. If we want to recognize the human's emotion from this facial image, we need to extract feature points such as action unit(AU) of Ekman. active appearance model (AAM) is one of the commonly used methods for facial feature extraction and it can be applied to construct AU. Regarding the traditional AAM depends on the setting of the initial parameters of the model and this paper introduces a facial emotion recognizing method based on which is combined Advanced AAM with Bayesian network. Firstly, we obtain the reconstructive parameters of the new gray-scale image by sample-based learning and use them to reconstruct the shape and texture of the new image and calculate the initial parameters of the AAM by the reconstructed facial model. Then reduce the distance error between the model and the target contour by adjusting the parameters of the model. Finally get the model which is matched with the facial feature outline after several iterations and use them to recognize the facial emotion by using Bayesian Network.

Abstract: In this paper, a method to reproduce realistic driving feeling and improve the returnability of steer-by-wire systems (SBW) is proposed by measuring the roadwheel motor's current directly. The key contribution presented here is a novel method to recreate the driving feeling in term of force feedback with simple and cheap current sensors. A current sensor is used to fully measure the steering torque on the rack of steering mechanism. This measured steering torque therefore, includes the overall effects of road conditions, aligning moments, tire properties and so on. Beside that, a free control scheme is proposed to improve returnability as well as the handwheel stability in a free motion. Moreover, during this research, the significant frequency effect of handwheel motions was found. This effect could be useful and valuable for improving steer-by-wire development based on torque-map based method. This method is investigated with simulation results using the control design and simulation module in LabVIEW programming language. The simulated results show that this method offers a cheaper and simpler solution for the development of steer-by-wire systems. In addition, stability and returnability of handwheel in steer-by-wire systems could be improved.

Abstract: Sound source localization systems in service robot applications estimate the direction of a human voice. Time difference information obtained from a few separate microphones is widely used for the estimation of the sound direction. The cross-correlation function is computed in order to calculate the time difference between the two signals. Inverse cosine function is used when the position of the maximum correlation value is converted to an angle. Because of the nonlinear characteristic of inverse cosine function, the accuracy of the computed angle is varied depending on the position of the specific sound source. In this paper, we propose an efficient sound source localization method using region selection. By the proposed approach, the region from 0deg to 180deg is divided into three regions and only one of the three regions is selected such that the selected region corresponds to the linear part of the inverse cosine function. Only the selected region is used for the sound source localization. Thus considerable amount of computation time is saved and the accuracy of the computed angle is improved. By simulations, it is shown that the estimation error by the proposed method is only 31% of that of the conventional approach.

Abstract: We propose a novel algorithm for improved localization of the mobile robots by fusing RFID localization system and ultra-sonic sensors. Because there are uncertainties in previous RFID localization system, we are focusing on the sensor fusion system, which removes the uncertainty of the robot location using the distance measurements by ultra-sonic sensors. We divide into 2 parts, which are GPE (global position estimation) by RFID localization system and LEC (local environment cognition) by ultra-sonic sensor. The scheme to remove the uncertainty is proposed, which are the modeling about the measurement noise for RFID localization system and to estimate the straight obstacle and circular obstacle in well-structural indoor environment by the ultra-sonic sensors. The hierarchical localization algorithm is proposed to estimate the position of the mobile robot from GPE and LEC and for robust localization under the unknown indoor environment.

Abstract: Kernel-based tracker shows robust performances in various object tracking technologies. Due to its robustness and accuracy, kernel-based tracker using mean-shift algorithm is regarded as one of the best ways to apply in object tracking technology in computer vision fields. However, it fails tracking when faced with a speedy object moving beyond its window size within one image frame interval time. These tracking failures are reduced with the use of target-adjusted kernel models proposed in this paper. Target-adjusted models are designed to reflect the target information that is collected during a sampling period. Same to the conventional kernel model in kernel-based object tracker, this model also contains the target information of both the color and the distance. Experimental results show that the time required for the calculations in tracking process is lessened so that causing less failure by applying this model. The target-adjusted model is designed to focus on the colors in the target object by using look-up tables. These look-up tables enable a system to reduce the size of the color bins in a model so that unnecessary trivial computations can be discarded.

Abstract: This paper addresses the problem of coordinating great numbers of vehicles in large geographical areas under network connective constraints. We leverage previous work on hierarchical potential fields to create advanced skills in multi-robot systems. Skills group together various field objectives to accomplish the performance requirements in response to highlevel commands. Our framework calculates trajectories that comply with priority constraints while optimizing the desired task objectives in their null spaces. We use a model-based dynamics approach that provides a direct map from field objectives to vehicle accelerations, yielding smooth and accurate trajectory generation. We develop a real-time software system that implements the proposed methods and simulates the coordinated behaviors in a 3D graphical environment. To validate the methodology, we simulate a large exploration task and demonstrate that we can effectively enforce the required constraints while optimizing the exploration goals.

Abstract: In a nuclear power plant (NPP), periodic sensor calibrations are required to assure sensors are operating correctly. However, only a few faulty sensors are found to be calibrated. For the safe operation of an NPP and the reduction of unnecessary calibration, on-line calibration monitoring is needed. In the previous study, principal component-based auto-associative support vector regression (PCSVR) was proposed for the sensor signal validation of the NPP. In this paper the error uncertainty limit monitoring (EULM) is integrated with PCSVR for the failure detection. This paper describes the design of an AASVR-based sensor validation system for a power generation system. Response surface methodology (RSM) is employed to efficiently determine the optimal values of SVR hyperparameters. The residuals between the estimated signals and the measured signals are inputted to the EULM to detect whether the sensors are failed or not. The proposed sensor monitoring algorithm was verified through applications to the turbine 1st chamber pressure in pressurized water reactor (PWR).

Abstract: Implementing monolithic DC-DC converters for low power portable applications with a standard low voltage CMOS technology leads to lower production costs and higher reliability. Moreover, it allows miniaturization by the integration of two units in the same die: the power management unit that regulates the supply voltage for the second unit, a dedicated signal processor, that performs the functions required. This paper presents original techniques that limit spikes in the internal supply voltage on a monolithic DC-DC converter, extending the use of the same technology for both units. These spikes are mainly caused by fast current variations in the path connecting the external power supply to the internal pads of the converter power block. This path includes two parasitic inductances inbuilt in bond wires and in package pins. Although these parasitic inductances present relative low values when compared with the typical external inductances of DC-DC converters, their effects can not be neglected when switching high currents at high switching frequency. The associated overvoltage frequently causes destruction, reliability problems and/or control malfunction. Different spike reduction techniques are presented and compared. The proposed techniques were used in the design of the gate driver of a DC-DC converter included in a power management unit implemented in a standard 0.35 mum CMOS technology.

Abstract: This paper shows that the optimal driving voltages of power MOSFETs can be well modeled by a linear function of the load current. Thanks to the linear model, the self-scaling gate drive technique is proposed to improve the light-load efficiency of DC-DC converters by reducing gate driving loss. The gate drive voltage is scaled dynamically with respect to load current change. The proposed self-scaling gate drive technique can attain about 5.8% incremental enhancement on light-load efficiency.

Abstract: This paper presents some experimental results and practical evaluations of neutral point clamping and flying capacitor hybrid three-level phase shifted soft switching PWM DC-DC high power converter with high frequency transformer and center-tapped rectifier. This new DC-DC converter developed for TIG, MIG and MAG arc welders is implemented by modifying the high-frequency-linked HB soft switching PWM DC-DC power converter with high side and low side two active edge resonant modular, which is proposed by the authors. The operating principle of the three-level soft-switching PWM DC-DC converter and its experimental and simulation results including phase-shifted angle vs. power regulation characteristics and power conversion efficiency characteristics in addition to power loss analysis are illustrated and discussed from a practical point of view, along with the remarkable advantageous points as compared with previously-developed soft switching PWM DC-DC converter. Finally, the improved three-level soft switching PWM converter version is also considered to suppress the circulating current due to phase shift pulse modulation principle. The PWM and PDM dual pulse modulation strategy is considered to extend its soft switching transition operation range.

Abstract: This paper proposes a novel control method for operation of a DFIG-based wind generator under unbalanced stand-alone loads, connected directly with stator terminal of the generator. The effect of unbalance condition at loads causes torque pulsations on generator and the stator voltage unbalance that degrade the dynamic behavior of control system. To eliminate the negative sequence components existing in generated stator voltages, the proposed compensation approach is developed based on the coordinated control of rotor-side controller (RSC) of the DFIG system. The main concern of this paper is the use of hybrid current controller (HCC), consisting of a proportional integral (PI) controller plus a resonant (R) compensator. For the sake of improvement, the HCC is executed in the positive synchronous rotating reference frame without considering decomposition of positive and negative sequence components of current values. Simulation is executed using PSIM, and experimental results are also shown in the paper to demonstrate the feasibility and efficiency of the proposed control method.

Abstract: This paper presents a three-phase four-wire grid-connected photovoltaic (PV) system to play as a power generator and active filter (AF) compensator. This system is flexible enough to efficiently remove current harmonic components and balance the line currents drawn from grid by an unbalanced nonlinear load. Simultaneously power conversion system injects the maximum power available from the PV array to the grid by using a fast and precise control strategy. The controller enjoys both modified PQ0 transformation and Fuzzy Logic Incremental Conductance (FL-IC) method to accomplish the Maximum Power Point operation Tracking (MPPT) of PV array. The control strategy is described and the whole system is built and simulated by PSCAD/EMTDC software with reference to different operation conditions. The results from simulations confirm the theoretical aspects of the proposed PV power supply and effectiveness of the control techniques to compensate non-linear unbalanced loads as well as utilization of the maximum PV power production.

Abstract: A new method of obtaining diagnostic data from induction motors, derived from the three supply currents using principal components analysis, is presented in this paper. The techniques presented here focus on extracting relevant information from spectral matrices. These techniques are qualified as parsimonious tools for exploring the behaviour of current vector valued signals in the frequency domain with minimal loss of information. In fact, the new diagnostic method obtains data from the three stator currents by exploring special fault characteristic frequencies in the power spectral density of the first principal component. The main advantage of this new diagnostic tool is its ability to extract automatically the characteristic frequencies relative to the different machine operating modes. This is accomplished using the proportion of the power attributed to the first principal component and/or using the sensor contribution to the power at specific frequencies. Thus, the new diagnostic method gives a good basis for an automatic non intrusive condition monitoring for rotating machinery.

Abstract: Ultrasonic feature detection is primarily based on the time-of-flight of the acoustic signals. Operating at their resonances, the transducers tend to produce long transients that exacerbate the effects of multi-echo interference and result in a loss of details and accuracy. In this work, a novel phase-dependent baseband model is developed to quantitatively describe the ultrasonic signals and the associated interference characteristics. A Fourier approximation algorithm is then applied to retrieve the timing information by separating the primary and secondary echoes from the received baseband echo signal to enhance the measurement resolution. The performance of the proposed algorithm is demonstrated by both numerical and experimental examples.

Abstract: A key challenge in the design of low power digital systems is the fast and accurate estimation of power dissipation. In this paper, we present a look-up-table (LUT) based power macromodeling technique for digital signal processing (DSP) architecture in terms of the statistical knowledge of their primary inputs/ouputs. During the power estimation procedure, the sequence of an input stream is generated by a genetic algorithm (GA) using input metrics. Then, a Monte Carlo zero-delay simulation is performed and a power dissipation macromodel function is built from power dissipation results. From then on, this macromodel function can be used to estimate power dissipation of the system just by using the statistics of the macro-block's primary inputs/outputs. The most important contribution of the method is that it allows fast power estimation of intellectual property (IP) based design by a simple addition of individual power consumptions. This makes the power modelling of SoCs an easy task that permits evaluation of power features at the architectural level. In order to evaluate our model, we have constructed IP-based DSP system using different IP macroblocks. In experiments with individual IP macro-blocks, the results are effective and highly correlated, with an average error of just 1-3%.

Abstract: Clustering based on a distortion-ratio criterion for data sets with large statistical differences of class data is treated, where K-Means algorithm (KMA) cannot necessarily reveal the good performance. After obtaining cluster centers attaining the minimum squared-error distortion or its approximation by KMA, clustering based on the distortion-ratio criterion, whose criterion provides a measure of the validity of clustering, is introduced. When the criterion is not satisfied, a split and merge procedure based on the distortion-ratio measure is executed. Focusing on an interesting data set which is not resolved by KMA, clustering based on the distortion-ratio criterion and the split and merge procedure is investigated.

Abstract: We propose a new classification algorithm, variance considered machine (VCM), by modifying optimal hyperplanes of the support vector machine (SVM). The SVM is a good method to calculate a slope of optimal hyperplanes with maximal margin. However, this algorithm neglects to consider variances and prior probabilities of the data. It can increase probabilities of error. To solve this problem, the VCM shifts the optimal hyperplanes of the SVM according to variances and prior probabilities. Therefore, the VCM has not only maximal margin, which is an advantage of the SVM, but also lower error probability. Through 10 case examples with different variances and prior probabilities, we demonstrated the superiority of the VCM by comparing the results of the SVM and VCM.

By the fact that the input coupling matrix B is not shown in the explicit formula of the solution to the input-derivative-constrained optimal regulator problem, the assumption of the known B matrix is relaxed. And then, partially model-free ADP technique given in [D. Vrabie et al.] is employed to this regulator problem in order to develop the model-free approximate dynamic programming technique. Moreover, using the inherent property of the input-derivative-constrained optimal regulator problem, we extend the proposed model-free ADP technique to the more general linear systems which include constant matching disturbances. The proposed technique can be considered an adaptive optimal controller since it updates the parameters in the controller in a way that the parameters converge to the optimal ones. The simulation is executed to verify the applicability of the proposed method.

Abstract: A novel method is presented for optimizing laser scribing of solar cell wafers for the isolation process. Multiple performance characteristics are optimized using grey relational analysis (GRA). Laser scribing technology is a useful solution for solar cell isolation processes. Solar energy is available worldwide and useful to everybody. Most solar cell technology is currently based on silicon wafer technology. Two important targets for this solar cell industry are high effective rates of energy transfer and low manufacturing costs. The isolation process for solar cell silicon wafer processing using laser scribing technology needs a high quality process to obtain a good surface profie. This study uses a Q-switched diode-pumped solid-state laser (DPSSL) to perform the scribing. Results are characterized using three parameters, including two laser operation parameters (laser average power and Q-switching frequency), and one laser scanning parameter (laser scribing speed for manufacturing throughput). These parameters are optimized based on multiple performance characteristics. Some characteristics of the scribing isolation process using laser technology for solar cell wafers are verified. The characteristics of interest are the minimum width of the average scribing groove for edge isolation on wafer substrates and the maximum depth of the average groove. Nine experiments were conducted using GRA to optimize the values for laser scribing parameters in order to generate various quality characteristics. Analysis of the grey relational grade indicates parameter significance and the optimal parameter combination for the laser scribing process is identified. The measured analytical results using the optimal parameters confirm that laser scribing technology can be effectively applied to isolate the edge of solar cell wafers.

Abstract: The purpose of the paper presented here is to deal with the well-known linear generalized predictive control (LGPC) scheme based on multiple models strategy for a tubular heat exchanger system.

In order to demonstrate the effectiveness of the proposed strategy, simulations are carried out and the outcomes are compared with those obtained using the nonlinear GPC (NLGPC) approach. The results can verify the validity of the proposed control scheme.

Abstract: This paper presents investigations into the development of input shaping with proportional-derivative (PD)-type fuzzy logic control for trajectory tracking and vibration control of a flexible joint manipulator. To study the effectiveness of the controllers, a PD-type fuzzy logic controller is developed for tip angular position control of a flexible joint manipulator. This is then extended to incorporate input shaper control schemes for vibration reduction of the flexible joint system. The positive zero-vibration-derivative-derivative (ZVDD) and new modified specified negative amplitude zero-vibration-derivative-derivative (SNA-ZVDD) input shapers are then designed based on the properties of the system for vibration control. The new SNA-ZVDD is proposed to improve the robustness capability while increasing the speed of the system response. Simulation results of the response of the flexible joint manipulator with the controllers are presented in time and frequency domains. The performances of the PD-type fuzzy logic with input shaping control schemes are examined in terms of input tracking capability, level of vibration reduction, robustness and time response specifications. A comparative assessment of the positive ZVDD and modified SNA-ZVDD shapers to the hybrid system performance is presented and discussed.

Abstract: This study evaluated the level of performance improvement in the form of a simulated experiment by adding fixed node in the middle of the network as a way to improve mobile ad.hoc network performance. The result showed that the performance level was much higher when fixed node was used together than when mobile node was used only, and the comparison of the mobile speed of mobile node also showed that use of fixed node together had higher performance.

Further study following this on how many fixed node should be added on the ad.hoc network will ensure establishment of more reliable ad hoc network.

Abstract: This research presents the development of a multi-fingered robot hand for the application of massage. Massage is a helpful treatment for human body conditioning and therapy. This is a relative new and feasible application of multi-fingered robot hands except for the use as prosthesis and grasping applications. For the dexterous manipulation of the robot hand, impedance control is adopted. Impedance control aims to generate a desired dynamical relationship between the motion of the end-effector and the reactive force at the contact region. For the safety and the comfort monitoring during massage, the measurement of human sensation information such as electromyographic (EMG) signals, pulse, skin temperature and conductance is introduced into the control system. Herein, we focus on the use of analyzed EMG signals as the feedback information for massage applications.

Abstract: This paper presents a novel control method for PWM boost rectifier based on instantaneous power. Unlike most of the existing control strategies implemented in synchronous or p-q (active-reactive power) frame, the proposed method can provide unity power factor on the AC side in stationary frame. Rotating transformation and phase detection are eliminated, offering a very simple solution. Based on the analysis of the instantaneous powers, a new method for current harmonic elimination is also proposed, which entails sinusoidal input currents under distorted source voltages. Compared with the conventional harmonic suppressing methods, the proposed scheme has a simple structure. Moreover, fast dynamic response is achieved in the presented algorithm owing to instantaneous power control. Simulation and experimental results on a 30 kVA PWM rectifier show satisfactory performance of the presented method both in steady and dynamic state.

Abstract: A series-resonant single-phase series-resonant AC chopper is presented. The presented single-phase AC chopper is configured by a series-resonant conversion without cycloconversion and auxiliary switches. The presented single-phase AC chopper is a series resonator with four main switches to configure adaptively the resonant voltage robes. The synthesized sinusoidal waveform (SSW) before output filter is synthesized by a series of sinusoidal amplitude quasi-sinusoidal pulses (QSPs) following the input voltage amplitude. Because the synthesized SSW very closes sinusoidal waveform, the presented single-phase AC chopper can use a simple LC filter to filter the undesired harmonics and get the sinusoidal voltage with low total harmonic distortion (THD). The presented single-phase AC chopper is operated by constant frequency pulse width modulation with control technique. Waveform syntheses for the output sinusoidal voltage are clearly analysed and derived. A typical design example of a 600 W series-resonant single-phase AC chopper is examined to assess the system performance. The power efficiency is over 91% when the output power is at maximum output rated power. The total harmonic distortion (THD) when the output power is at maximum output rated power is within 5%.

Abstract: It is well-known that ultra-low-power three-phase elements, such as ultra-small-size permanent-magnet brushless motor drivers, have been widely used in the consumer products. In order to reduce the cost, size and power consumption of products, it is necessary to integrate the system functions with square-wave PWM (SWPWM) driver in the system-on-chip (SOC) implementation. It follows that, the driver loss and loss distribution are the main challenges in the integration of ultra-low-power SWPWM driver where the driver loss include conducting loss, switching loss and gate driving loss, where the last one is often neglected in other low-, medium- and high-power drivers. On the other hand, there are 16 types and 64 types in 120-degree SWPWM and 180-degree SWPWM, respectively, and the resulting driver loss and loss distribution differ from each other. This paper studies the driver loss and loss distributions of all SWPWM types in detail. The result shows that SWPWM type-01_01, type-10_10 and type-010_010 are the recommended types in the SOC integration of ultra-low-power SWPWM driver.

Abstract: This paper presents a comparison in efficiency between a fuzzy logic controller (FLC) and a proportional-integral (PI) controller based interior permanent magnet synchronous motor (IPMSM) drive incorporating an online loss minimization algorithm (LMA). The LMA is developed based on the motor model. In order to maximize the operating efficiency, the d-axis armature current is controlled optimally based on the developed LMA. A novel fuzzy logic controller (FLC) is developed in such a way that it can simultaneously control both torque and flux of the motor while maintaining current and voltage constraints. Thus, the FLC extends the operating speed limits for the motor. The LMA is incorporated with the FLC so that the motor can operate over wide speed range while maintaining the high efficiency. A performance comparison of the LMA based IPMSM drive with FLC and PI controller is provided. Simulation results demonstrate the higher efficiency and better dynamic response of the FLC based drive as compared to the PI controller over a wide speed range. The complete drive is also experimentally implemented using DSP board DS1104 although the complete experimental tests are yet to be done.

Abstract: It is known that control strategies for most electrical machines are derived based on machine parameters, which are constant for most of the excitation range. However, due to the salient pole nature of Switched Reluctance Motor (SRM), the machine inductance is not only a function of the rotor angle but also is a function of the excitation current. This complicates the development of control strategies for such drive systems. The position information requirement is a limitation of SRM. The shaft position sensors are normally used for this purpose. These sensors reduce the reliability of the drive. Efforts are on to replace the position sensor with suitable estimation technique. In this paper, an overview of the different existing sensorless starting methods and their shortcomings are explained and finally, a starting method is proposed. Also this paper presents a method of position estimation for SRM. The method is suitable from starting to full speed. It ensures smooth starting without initial hesitation.

Abstract: Nonlinear adaptive speed and d-axis current control schemes based on adaptive state feedback and backstepping technique are proposed for a permanent magnet synchronous motor (PMSM). In the controller design, adaptive state feedback and backstepping control approach using the parameter dependant Lyapunov function is adopted to derive the control scheme, which is robust to the all parameter uncertainties and the load torque disturbance, force the whole control system to have the output strictly passivity. Moreover, because of using a parameter dependant Lyapunov function, proposed controller has no singularity problem. Simulation results clearly show that the proposed control scheme can regulate the speed and the d-axis current reference under all parameter uncertainties and the load torque disturbance.

Abstract: Currently, in order to meet customer requirements about safety and convenience, many electronics and software are used in automobiles. Because high amount of data from each electronics and software needs to be communicated fast and correctly, performance evaluation of in-vehicle network is necessary. FlexRay protocol that is suggested to guarantee exact operation of in-vehicle subsystem such as x-by-wire application has emerged as de-facto standard. However, there are only a few researches about response time analysis and timing performance verification.

We define system model for the algorithm and carry out performance evaluation using SAE benchmark data. Though the evaluation, we show that network utilization in all transmission speed is reduced, and also in lower transmission speed, it is reduced much more.

Abstract: In a safety-critical real time system it is important to prevent the babbling idiot failure (BIF), which is characterized by a faulty node transmitting arbitrary messages at random points in time. However, existing communication systems based on flexible time division multiple access (FTDMA), whose development was driven explicitly by the new needs of future in-car control applications involving safety-critical functions, do not provide any efficient solution to avoid the BIF. Therefore, a bus guardian (BG) solution is presented to avoid the BIF in a FTDMA based communication system in this paper. The supervision algorithm of the proposed BG is presented along with the node architecture necessary for implementing the presented technique. Results of performance evaluation show that the proposed BG can enforce the error containment in the time domain of FTDMA based systems and help to make them appropriate for safety-critical applications.

Abstract: The dependence of intelligent vehicles on electronic devices is rapidly increasing the concern over fault tolerance due to safety issues. For example, an x-by-wire system, such as electromechanical brake system in which rigid mechanical components are replaced with dynamically configurable electronic elements, should be fault-tolerant because a critical failure could arise without warning. Therefore, in order to guarantee the reliability of safety-critical systems, fault-tolerant functions have been studied in detail. This paper presents a Kalman predictive redundancy system with a fault-detection algorithm using the Kalman filter that can remove the effect of faults. This paper also describes the detailed implementation of such a system using an embedded microcontroller to evaluate the performance of the Kalman predictive redundancy system. The experimental results show that the Kalman predictive redundancy system can ensure the fault-tolerance of safety-critical systems such as x-by-wire systems.

Abstract: In this paper we design three programs, the first one is an automatic network RF signal measurement (ANRSM), the second one is automatic RF module and baseband hardware device self-diagnosis SmartMobileTest, and the last one is RF remote control test program (RRCTP). The greatest advantages of our ANRSM and our SmartMobileTest are that they are of a small size with portability, and that they reduce both the test time and the complexity of RF test programs. Our ANRSM is written in C++ language. This program uses the embedded 3GPP RF Spec TS 51.010 and by means of virtual instrument software architecture (VISA) controls the General Purpose Interface Bus (GPIB) which is used to control the RF base station simulator. Moreover we use LabVIEW and Web publishing technology to develop RRCTP to implement the remote control and command exchange. The SmartMobileTest program is created on a Windows Mobile OS to test the function of the RF and baseband module. Both our ANRSM and our SmartMobileTest support RF automatic testing and detection for the hardware performance of all the RF and baseband modules in a Smartphone. By combining these two programs we are able to identify the effect of both RF sensitivity and noise quickly.

Abstract: Measurement of free-form surfaces is a requirement to assure quality and to reduce manufacturing costs and rework. An on-line measurement system combined coordinate measuring machine (CMM) and numerical controlled (NC) sandblast manufacturing equipment for large surface is presented in this paper. It uses transmission and position functions of NC machine and CMM's scan measuring function to make large surface measurement correspondingly. By means of auxiliary coordinate axis, CMM and NC machine can establish a unified coordinate system, data transform and on-line measurement. To perform detailed comparison of the shapes, the CAD model is geometrically adjusted with the input using model-based a new matching algorithm developed in this paper. Once the CAD model is adjusted, it is compared with input to reveal the errors between their shapes. Following, process parameters in NC machine will be adjusted by the expert system based on the errors and neural networks. In this way the integration of on-line measurement and NC manufacturing have been accomplished.

Abstract: Most of the reported Distributed Video Coding (DVC) schemes have a high time-delay in decoder which hinders its practical application in real-time systems. In this paper, we propose a new DVC decoder architecture based on MPI clusters and an efficient parallel algorithm for generation of the Side Information (SI) based on the structure. In order to achieve a balanced workload among the processors and minimize the overheads of inter-process interaction, we adopt a task-pool model to implement dynamic mapping of tasks onto processors. In addition, the proposed method also uses a threshold-based approach to attain good trade-off between decoding time and video quality. We analyze the effect of computational granularity and the number of processors on performance through defining a performance function. The experimental results on multicore PCs show that a near-linear speedup can be obtained by using the proposed parallel SI generating algorithm.

To validate the performance, a number of standard test sequences are used. Simulation results demonstrate that the proposed algorithm dramatically outperforms the Exhaustive Search (ES), the Three-Step Search (TSS), the Diamond Search (DS) and the Adaptive Rood Pattern Search (ARPS) algorithms. The simulation results show that the proposed algorithm is about 3.33~17.12 times faster than that of TSS, 2.12~8.99 times faster than that of DS, and 1.15~4.42 times faster than ARPS, while achieving close performance in terms of the Peak Signal-to-Noise Ratio (PSNR).

Abstract: This study presents an integrating decision approach, based on a model-based and rule-based decision approach, to detect and classify highlight events in baseball games. The model-based approach is proposed to model the relationship between the change statuses of the caption data and some events. The approach uses some binary bits to represent the amount of the changes. The rule-based approach is proposed to use the conditions of the caption data to elicit the empirical knowledge and to decide what some events is happened. Finally, the proposed approach integrates the complementary and redundant resulting of the two approaches to enhance the classification performance. Experimental results demonstrate that the proposed approach is very efficient for classifying highlight events. Furthermore, the performance of the proposed approach can be improved by 6.58% over the average of the model-based and rule-based approaches.

Abstract: In this paper, we propose corrected artifact detection for motion compensated de-interlacing. De-interlacing techniques are adopted to convert interlaced video into progressive scanning format. Motion compensated de-interlacing algorithm provides the best performance if the estimated motion information is correct. However, it suffers from inaccurate motion estimation, and the weak error protection thus deteriorates the visual quality. This paper presents corrected artifact detection for motion compensated de-interlacing with highly accurate motion estimation and robust error detection. We propose a spatial-temporal correlation assisted motion estimation to obtain more accurate motion information. The spatial and temporal correlations among the motion vectors are exploited to find the true motion of the object. A hierarchical MV reliability verification is provided to reject incorrect temporal information. This method can detect the possible defects effectively in both large and small areas. The experimental results show that the proposed scheme outperforms existing methods and converts high performance de-interlaced results in different video sequences.

Abstract: This paper proposes a novel music information retrieval system (music genre and music mood classification system) based on two novel features and a weighted voting method. The proposed features, modulation spectral flatness measure (MSFM) and modulation spectral crest measure (MSCM), represent the time-varying behavior of a music and indicate the beat strength. The weighted voting method determines the music genre or the music mood by summarizing the classification results of consecutive time segments. Experimental results show that the proposed features give more accurate classification results when combined with traditional features than the octave-based modulation spectral contrast (OMSC) does in spite of short feature vector and that the weighted voting is more effective than statistical method and majority voting.

Abstract: A discriminative training algorithm to estimate continuous-density hidden Markov model (CDHMM) for automatic speech recognition is considered. The algorithm is based on the criterion, called margin-enhanced maximum mutual information (MEMMI), and it estimates the CDHMM parameters by maximizing the weighted sum of the maximum mutual information objective function and the large margin objective function. The MEMMI is motivated by the criterion used in such classifier as the soft margin support vector machine that maximizes the weighted sum of the empirical risk function and the margin-related generalization function. The algorithm is an iterative procedure, and at each stage, it updates the parameters by placing different weights on the utterances according to their log likelihood margins: incorrectly-classified (negative margin) utterances are emphasized more than correctly-classified utterances. The MEMMI leads to a simple objective function that can be optimized easily by a gradient ascent algorithm maintaining a probabilistic model. Experimental results show that the recognition accuracy of the MEMMI is better than other discriminative training criteria, such as the approximated maximum mutual information (AMMI), the maximum classification error (MCE), and the soft large margin estimation (SLME) on the TIDIGITS database.

Abstract: Recently, renewable energy such as wind turbine generator and photovoltaic system are introduced as distributed generators (DGs). Connection of a large amount of distributed generator causes voltage deviation beyond the statutory range in distribution system. Reactive power control of inverter interfaced with DG is one of the solutions against this problem. Additionally, reactive power control has a possibility to contribute for reduction of distribution loss. In this paper, we propose a voltage control method in distribution system by reactive power control of inverters interfaced with DGs. The proposed method has been developed with the aim of reduction of distribution loss and voltage regulation into statutory range without any telecommunications. In the proposed method, each interfaced inverter controls reactive power based on voltage control reference, which is calculated from local measurements. The calculation rule of control reference has been developed using optimal data, which consist of relations between ramdomly given inputs and corresponding optimal outputs calculated by an optimization technique. Simulations are conducted to show the effectiveness of the proposed method.

Abstract: The process of categorizing packets into flows in an internet router is called packet classification. All packets belonging to the same flow obey pre-defined rules and are processed in a similar manner by the router. Packet classification is needed for non best-effort services, such as firewalls and quality of service, services that require the capability to distinguish and isolate traffic in different flows for suitable processing. The different services are packet filtering, policy routing, accounting and billing, traffic rate limiting, traffic shaping etc. Packet classification can be done on a single field or multiple fields. There are a variety of algorithms proposed for packet classification. They can be broadly categorized as basic data structures / search algorithms, geometric algorithms, heuristic algorithms and hardware specific algorithms. In this paper a review is taken of various packet classification algorithms of the above mentioned categories.

Abstract: OFDM (Orthogonal Frequency Division Multiplexing) technique has been widely adopted in many wireless communication systems due to its high data-rate transmission ability and robustness to the multipath fading channel. One major drawback of the OFDM signal is the high peak-to-average power ratio (PAPR) problem. The high PAPR results in the in-band distortion and out-of-band radiation when the OFDM signal is fed into a nonlinear power amplifier (PA). In this paper, we propose a partition dummy sequence insertion (PDSI) method to reduce the PAPR problem and compare with the DSI method. Simulation results of the PAPR reduction and bit error rate (BER) performance for the proposed method are performed to demonstrate its capabilities.

Abstract: Intelligent robotic navigation requires precise positioning information. The Global Navigation Satellite System (GNSS) enables such navigation by providing precise timing, velocity and positioning information to any adequately equipped receiver world-wide. A core capability of these receivers is to identify all visible satellites from a snapshot of received signal. This identification process, called signal acquisition, must be performed in shortest possible time in practical solutions. Conventionally search for the desired satellite in a serial fashion which involves large number of computations. Recently Fourier transform based methods were proposed to speed up the processing. However such a solution requires complex domain signal processing. We propose a partial-code serial search algorithm that significantly reduces the computational time with same reliability of acquisition results.

Abstract: In manufacturing industries of metallics molds, various NC machine tools are used. We have already proposed a desktop NC machine tool with compliance control capability to automatically cope with the finishing process of LED lens molds. The NC machine tool has an ability to control the polishing force acting between an abrasive tool and workpiece. The force control method is called impedance model force control. The most important gain is the desired damping of the impedance model. Ideally, the desired damping is calculated from the critical damping condition in consideration of the effective stiffness in force control system. However, one of the serious problems is that the effective stiffness of the NC machine tool has undesirable nonlinearity. The nonlinearity gives bad influences to the force control stability. In this paper, a fine tuning method of the desired damping is considered by using neural networks. The neural networks acquire the nonlinearity of effective stiffness. It has been observed that the desired damping generated from the learned neural networks allows the NC machine tool to achieve a stable finishing result.

Abstract: The safety of humans working with robots is an important issue. Many studies have addressed related methods, but fundamental limits to meet required safety have been met owing to the absence of compliance in the robot actuators. Pneumatic muscle is considered to be a basic actuator and offers the advantage of intrinsic elasticity to achieve the joint compliance. Here, the joint compliance actuated by pneumatic muscle is actively utilized to enhance human safety during collisions. To this end, the authors present a novel approach to control compliance and position independently without affecting on the each other's performance using pneumatic muscles. The presented method is verified by experiments using a physical robot.

Abstract: This paper proposes a method for controlling posture of a robot manipulator by fuzzy voice commands. Human-friendly robotic system should be able to understand the fuzzy linguistic information based on the user's guidance and the environmental conditions. The contextual meaning of fuzzy linguistic information depends on the conditions of the environment. Therefore, the user's feedback is evaluated to understand the fuzzy linguistic information related to the posture movements. The primitive posture movements are evaluated by the behavior evaluation network (BEN). Feedback evaluation system (FES) is introduced to evaluate the user's feedback to correct the robot perception by adapting the BEN. The capability of evaluating fuzzy linguistic information based on the current context is enhanced. A selected set of posture movements are used to illustrate the system by using a PA-10 robot manipulator.

Abstract: This article presents the design and analysis of a controller based on a biologically inspired central pattern generator (CPG) network of mutually coupled Matsuoka nonlinear oscillators to generate adaptive rhythmic human like movement for biped robots.. The paper focuses on the way in which the sensory signals feedback contribute to generate dynamic, stable and sustained rhythmic movements with robust gaits for biped robots. In addition, the paper shows how the driving input and external perturbation affect the speed of locomotion and change the period of its own active phase. The new design was studied through interaction between simulated interconnection coupling dynamics with 6 links and a musculoskeletal model with 6 degrees of freedom (DOFs) of a biped robot. The robot used the weighted outputs of mutually inhibited oscillators as torques to actuate its joints. The implemented model helps to realize the interaction between the controller, the mechanism of the robot, and the environment. In addition, it helps to study the necessary conditions for efficient generation of stable rhythmic walking at different speed, on different type of terrains and robustness in response to disturbances. Evaluations of the developed CPG based adaptive bipedal locomotion are carried out through simulations with successful testing results.

The main contribution is reducing the complexity of the matching process, which is the most complex step in local localization algorithm for mobile robots. We examine validity of our algorithm with various simulations and experiments, and also revealed accuracy and reduction of computational time of the matching process compared to conventional localization algorithms.

Abstract: This paper presents a dynamic simulation model for a hybrid electric scooter (HES) designed by NPUST in Taiwan. The HES is built in a parallel hybrid configuration with a 24 V 370 W auxiliary power electric motor, a 24 V 600 W generator, a 24 V 15 AH battery, and an electronically controlled fuel injection internal combustion engine (ICE). Because the system is complex and nonlinear in nature, the simulation model utilizes mathematical models in tandem with accumulated experimental data. The methods used to construct the model and to prepare experimental data are fully described. Efforts are made to accurately predict key system parameters including engine speed, velocity, CVT gear ratio, battery state of charge (SOC), and fuel consumption rates during an ECE-40 driving cycle test. The efficacy of the model was verified experimentally with a scooter chassis dynamometer; parameters predicted by the simulation model are seen to be in excellent agreement with those of experiments.

Abstract: A haptic system is an articulated mechanical structure with motors, sensors as well embedded electronics allowing force feedback. It enables the user to interact with virtual reality through the sense of touch and sight. Speed control of such systems usually becomes unstable at low speed range due to the imposed speed by the operator's hand. This paper describes the implementation of a full order state speed observer as well as a Kalman filter for a single degree of freedom haptic interface driven by a permanent magnet synchronous motor. Those two methods allow accurate speed estimation. The observer and the filter design procedure for haptic interface are analyzed in this paper. In addition, their influence on system stiffness is illustrated, taking into consideration variations of the system inertia.

Abstract: In this paper a Vienna I rectifier is used to achieve active filtering function including the neutral wire current compensation (VR-AF) in a three-phase four-wire system. A linear quadratic with integral action regulator (LQIR) is designed to achieve overall DC bus voltage regulation, harmonics, reactive power and load's neutral current compensations. The converter model is set in the d-q-o rotating reference frame. The latter is augmented with the integral of the q and o components of the (VR-AF) currents and overall DC bus voltage to achieve integral action. The converter is controlled as a multi-input multi-output (MIMO) system and a fixed PWM at 10 kHz is used to generate the gating signals of the power devices. The system is tested for harmonics, reactive power and load unbalance compensation for balanced/unbalanced loads. The simulation results obtained with SPS and Simulink of Matlab show good performance in terms of overall DC bus voltage regulation; line currents shaping, balancing and neutral current mitigation which proved the effectiveness of the adopted control strategy.

Abstract: A dual resonant converter using active clamp circuit is presented in this paper. The active clamp circuit is employed to limit the voltage stress and create zero-voltage-switching (ZVS) turn-on feature for power switches. Moreover, the dual resonant tanks are composed by the leakage inductors and resonant capacitors to achieve zero-current-switching (ZCS) turn-off mechanism for diodes at the secondary side of transformer. Hence, the reverse-recovery problem can be eliminated. The operational principles, design consideration and realization are discussed. Finally, experimental results from a 400W prototype are presented to confirm the effectiveness of the proposed converter.

Abstract: Matrix rectifier is evolved from the traditional three phase to three phase matrix converter, and inherits merits of the traditional matrix converter, so it obtains more attention in recent years. According to transformer, matrix rectifier topology falls into the isolated and non-isolated topology. Now the existed modulation strategy mostly focuses on space vector modulation study and is realized difficultly. This paper adopts isolated matrix rectifier topology and proposes a novel SPWM modulation strategy based on absolute value logic, which can realize unit power factor and DC voltage output, and makes transformer keep voltage-second balance in a high frequency switching period. Experiments are done with DSP and CPLD based on the matrix rectifier platform. Simulations and experiments well prove the validity and feasibility of the proposed modulation strategy.

Abstract: Modulation theory is widely used for power converter analysis, but it has limited number of equations and it isn't general for all cases. To solve the two problems, the paper investigates all work states of three-phase inverter under phase control with 180-degree conduction. By analyzing the relationship of voltages and currents between the two sides of a inverter, four groups of modulation equations are derived. These equations are different from the present modulation equations. They enrich the modulation theory, and they can be used as flexible and powerful tool for the modeling and analysis of power converters. Case study validates the effectiveness the proposed modulation equations.

Abstract: Based on the mathematical model of the current source inverter (CSI) in the stationary alphabeta frame, this paper proposes advanced stationary frame voltage control methods for CSI with linear and nonlinear loads to achieve zero steady-state error respectively. The voltage control strategy based on a special resonant controller for CSI with linear loads is firstly analyzed in detail, on the basis of which, the voltage control method for CSI with nonlinear loads is proposed and the principle of it is investigated. Because the alphabeta components of CSI output voltage are decoupled in the stationary frame, they can be controlled independently and the controllers can be designed easily. Meanwhile, these voltage control methods don't require accurate circuit parameters, so they can also improve the control system's robustness. At last, all these analyses and the effectiveness of the proposed control methods are firstly validated by simulation, and then are verified further in a 5 kVA laboratory prototype.

Abstract: Wind turbine systems (WTS) based on permanent magnet synchronous generators (PMSG) have been gaining more and more importance over the last years. In fact, these generators are self-excited, allowing operation at high power factor and high efficiency. Additionally, the elimination of the gearbox allows a reduction in costs and maintenance. To further reduce the system complexity and the maintenance process, sensors normally used to sense the speed of these generators could be eliminated. This aspect is particularly important for wind turbine installation in harsh environment characterized by extreme weather conditions. To this purpose this paper investigates how a phase locked loop (PLL) can be profitably used to estimate the rotor speed. A systematic analysis is presented as well as simulation and experimental results proving the feasibility of such solution.

Abstract: The new generation of field-stop (FS) IGBT integrates the advantageous of former generations and adopts the latest power semiconductor manufacture technology, which enhances its power rating and synthesis performance remarkably. The IGBT physics-based simulator model is a useful tool for device manufacture and application, but the difficulty and complexity of existed parameters extraction methods limit the employment of these models, which also restricts the development of device application and system design level. Furthermore, these methods are not suitable for the new IGBT with a FS layer structure differ with the conventional PT and NPT IGBT. Based on its physical structure and work principle, this paper proposes some new parameters extraction methods for FS IGBT through the data measured from its three electrical ports. The extraction circuits and experiments to a EUPEC IGBT are also introduced, the results of experiments under different working conditions show good consistency, which also proves the accuracy of proposed methods. These extracted parameters are useful for devices structure design, performance optimality and application of the IGBT technology.

Abstract: This paper proposes a robust torque estimation strategy for synchronous reluctance motors (SynRMs) to magnetic saturation using a full-order flux observer, which is based on a new linear flux model. SynRMs possess considerable magnetic nonlinearity, which causes difficulty in obtaining optimal torque control. Thus, to realize optimal torque control, the torque profile needs to be defined according to current amplitude and phase. Finding torque profile, however, also tends to be complicated due to its magnetic non-linearity. This paper proposes a simple torque estimation technique using a full-order flux observer, which can realize torque estimation that is less sensitive to magnetic saturation and core loss. In addition, experimental results show the feasibility of the proposed strategy in this paper.

Abstract: In this paper we use an embedded system and an external interface circuit to design and implement an embedded network arbitrary signal generator (ENASG). We build a Web server in the embedded system and use CGI (common gateway interface) as the network interface between the Web server and the embedded system. The user can use a PC, a PDA or a smart phone to login to the remote operation interface. After the user has selected and adjusted the output waveform, it is outputted through the external interface circuit. For the ENASG we design four waveform types: sine, square, triangle and arbitrary. The frequency and the voltage of the output waveform are adjustable. The external interface circuit includes the data buffer, the digital-to-analog converter (DAC), the oscillator and the amplifier. The data buffer receives and stores the output waveform data from the embedded system. The oscillator controls the DAC to load the output waveform data and to convert the data into an analog signal. Finally, the amplifier gains the analog signal which is then outputted.

Abstract: For consumer products of the digital age, dasiastablepsila clock signals are crucial, leading to similar requirement for industrial instrumentation. In order to reduce jitters, rapid fluctuation in frequency, for such applications, this article proposes a novel configuration. Feed-forward compensator improves jitter filtration, without sacrifice in the reduction of inherent jitters. Adaptive gain, which is set high for locking and low for jitter filtration after locking, yields fast responses while keeping jitters low, as well. Its effectiveness is verified on a prototype implemented by an FPGA, and experiments as a multiply-by-50 synthesizer result in 30-fold reduction for inherent jitters and no amplification of incoming jitters.

Abstract: An active-clamping quad-flyback converter is proposed to achieve zero voltage switching (ZVS) for all power switches. The secondary sides of quad-flyback converter are connected in parallel to share the load current. Thus, the transformer copper losses and the conduction losses on the output diodes are reduced. Active-clamping part including one auxiliary switch and one clamp capacitor can release the energy stored in the magnetizing and leakage inductances such that the voltage stress of main switch is clamped and main/auxiliary switches can be turned on at ZVS. In the proposed circuit, the constant switching frequency with asymmetrical PWM waveform is generated to realize the ZVS turn-on of switches at the transition interval between main and auxiliary switches. Thus, the switching losses and thermal stresses of the semiconductors are reduced. The operation principle, system analysis and design consideration of the proposed converter are discussed in detail. Finally, a prototype of the proposed converter is implemented by 200 V input voltage, 48 V output voltage, 480 W output power and 90 kHz switching frequency to verify the theoretical analysis and the effectiveness of the proposed converter.

Abstract: The green energy transfer with isolation is used to transfer the energy which can not be used directly to the energy which can be utilized directly. This is achieved via switching control, i.e. duty-cycle control. However, by this way, the low-duty cycle is likely to deteriorate the utilization effectiveness of semiconductor devices and magnetic components. Consequently, to conquer this problem, a novel control topology is proposed herein and applied to a two-stage isolated voltage-boosting DC-DC converter with synchronization of gate driving signals considered, along with some simulated and experimental results provided to demonstrate its feasibility.

In the paper, the details of this positive-sloped ramp wave injection method are illustrated. And, some experimental results are provided to verify the effectiveness of the proposed control strategy.

Abstract: Closed loop PWM DC-DC switching converter is strongly nonlinear, and the analytical solution is difficult to be achieved. Oscillation and impulse voltage will probably occur in the output during the starting period in DC-DC converters. In this paper, a pulse-width-modulation(PWM) buck converter is used as an example to discuss such problems so as to predict them in the course of design, and reduce or even avoid above harmful phenomena by modifying the parameters. In order to investigate the dynamic behavior in the output voltage of the converters, differential equations for inductor current profile and output voltage profile are established. The equations are based on the assumption that the frequency of inductor current profile and output voltage profile are much lower than the switching frequency of the converter. The condition leading to oscillation and impulse voltage in the output is obtained. The oscillation frequency, the time that the impulse voltage occur and the max value of impulse voltage are also derived. The proposed approach is verified by PSPICE simulation and experiment results.

The output power is controlled using the asymmetrical voltage cancellation technique. The LLC resonant tank is designed with a matching transformer in between the series inductor and paralleled LC resonant tank for short circuit protection capability of the matching transformer and the induction coil. The validity of the proposed method is verified through computer simulation and hardware experiment at the operating frequency of 108.7 to 110.6 kHz.

Abstract: A 3-phase 4-wire diode-bridge rectifier is one solution of the front-end DC power for high power multilevel inverter. The average-value model (AVM) of 3-phase 4-wire diode-bridge rectifier under continuous conduction mode (CCM) within generator-rectifier system is presented based on state-space averaging method. The AVM is validated using the corresponding switching model of rectifier by simulations in the Matlab/Simulink environment, and using a hardware test system composed of a synchronous generator and its 3-phase 4-wire diode-bridge rectifier load. The results show that the AVM can captures the key steady-state and transient characteristics of the rectifier, and the agreement of DC voltage between the AVM, the switching model, and the hardware circuit are well. The model presented herein can be used for modeling, impedance mapping, and stability assessment with small disturbance of such generator (transformer) -rectifier systems.

Abstract: Vehicle license plate recognition (VLPR) is one of the most important topics of using computer vision and pattern recognition in intelligent transportation systems. In order to recognize a license plate (LP) efficiently, the location of the LP in most cases must be extracted in the initial step. In this proposed algorithm, initially, HSI color model is adopted to select automatically statistical threshold value for extracting candidate regions. According to different colored LP, these candidate regions may include LP regions; geometrical properties of LP are then used for classification. The proposed method is able to deal with candidate regions under independent orientation and scale of the plate. Finally, the decomposition of candidate regions contains predetermined LP alphanumeric characters by using position in the histogram to verify and extract vehicle license plate (VLP) region. Experimental results show that the proposed method is very effective in coping with different images under the variety of conditions such as complex scenes, illumination changing, distances and varied weather etc.

Abstract: MPEG-4 Part-10 AVC/H.264 (H.264/AVC) is the newest video coding standard developed and finalized in March 2003 by the Joint Video Team (JVT) of ISO/IEC (MPEG) and ITU-T (VCEG). It includes many powerful features such as multiple reference pictures, variable block-size motion compensation, quarter-pel accuracy motion compensation, and so on. As a result, it achieves high coding performance but at the expense of huge computational complexity. To reduce the complexity while keeping the same coding performance, we propose a low complexity subpel motion estimation method using two content-aware decision criteria. Based on the criteria, four different levels of subpel motion estimation are proposed to achieve low complexity subpel motion estimation. Simulation results show that the proposed method reduces total encoding time by 55.53% on average and subpel motion estimation time by 82.2% on average.

Abstract: A high-speed camera is essential for observing dynamic phenomena. Such a camera needs a bright lens with large aperture due to the short exposure time. Since the depth of field (DOF) becomes shallow when using a bright lens, there is a demand for a high-speed camera with an extended depth of field. One commonly used technique to extend the DOF is to synthesize images captured at various focus positions. However, this method cannot be applied to a high-speed camera because no conventional mechanism can shift the focus position quickly enough. In this paper, we propose a new high-speed variable-focus optical system for extending the DOF. The proposed optical system is based on a high-speed variable-focus liquid lens with millisecond-order response time that was developed by our group. We show that our proposed system results in better light intensity than the method involving decreasing the diameter of the aperture stop. Furthermore, our experiment demonstrated that a 1000-fps movie with extended DOF was successfully acquired using the high-speed variable-focus optical system in combination with the image synthesizing technique.

Abstract: The pattern on the finger face is composed of various size of creases, knuckle lines and subcutaneous vascular tubes. The patterns, shapes and sizes of fingers are different from person to person. These features are unique and peculiar to each person such that it can be used as the information for the process to identity an individual. In this paper, the properties of the features on finger face are analyzed and a method of distinguishing a person by the features of finger patterns, shapes, and sizes is presented. All of these features of a finger are able to be represented by a set of matrices obtained through a computation using FFG(Facet function gradient) masks. The gradient and the curvature at each patch in an image are able to be computed by certain operations with the elements of the matrices. In this paper we introduce an algorithm to identify the finger features using the matrices. It is possible to recognize not only the finger pattern but also the shape and size of the finger by this method. Recognition rate is turned out to be 98.2% in an experiment using the method suggested.

Abstract: For the purposes of this paper, a study of quality monitoring technology for the laser welding was conducted. Laser welding and industrial robotic systems are used with robot-based laser welding systems. The laser system used in this study was IPG's 1.6 kW fiber laser (YLR-1600), while the robot system was Hyundai Heavy Industry's HX130-02 (payload:130 kg). The robot-based laser welding system was equipped with a laser scanner system for remote laser welding. The welding joints of steel plate and steel plate coated with zinc were butt and lapped joints. The quality testing of the laser welding was conducted by observing the shape of the beads on the plate and the cross-section of the welded parts, analyzing the results of mechanical tension test, and monitoring the plasma intensity by using plasma detector. Over the past three years, Trumpf's 4 kW Nd:YAG laser (HL4006D) and ABB's IRB6400R robot system (payload:120 kg) was used. The new laser source, robot and laser scanner system are used to increase the processing speed and to improve the efficiency of processes. This paper proposes the robot-based remote laser welding system as a means of resolving the limited welding speed and accuracy of conventional laser welding systems.

Therefore, it is difficult for only conventional feedback control system to realize the high-precision and robust tracking control system. This paper proposes high performance tracking control system for optical disk which is a perfect tracking control based on a plant system and zero phase low pass filter. The experimental results point out that the proposed system realizes the high precision tracking control on condition of the disk rotation speed 7,200[rpm], which is equal to conventional HDD disk speed.

Abstract: Against vertical Sobel operator that most license plate detection (LPD) algorithms adopt, this paper presents a robust and real-time preprocessing method to enhance both edge density and intensity of license plates under various outdoor and indoor environments. The proposed method applies HL subband feature of 2D discrete wavelet transform (DWT) twice to significantly highlight the vertical edges of license plates and suppress the surrounding background noise. Then, several promising candidates of license plates can easily be extracted by first-order local recursive Otsu segmentation and orthogonal projection histogram analysis. Finally, the most probable candidate is selected out by edge density verification and aspect ratio constraint. Experimental results show LPD system based on the proposed 2-level 2D Haar DWT is better than that based on conventional vertical Sobel operator or 1-level 2D Haar DWT in terms of the detection rate.

Abstract: There are many important applications in printed electronics and publishing industries that use the principle of roll-to-roll manufacturing to make devices at high speeds with lower cost. Web velocity and tension control algorithm plays an important role in improving the quality of product in mass processing of using roll-to-roll web technology. Most algorithms proposed in recent years use PI or PID controllers and disturbance compensation schemes to increase the precision and the stability. Due to the increasing demand of high accuracy in printed electronics industry at micrometer-level, it is necessary to have a precise control scheme of web velocity and tension in the presence of disturbances. In this paper, a precise control algorithm is proposed for non-linear single-span roll-to-roll web control system using the back-stepping controller with the design parameters chosen optimally by using the modified genetic algorithm. The outcome of this study proves the reliability throughout simulation results in Matlab/Simulink and comparison with the existing results employed by PI controllers.

Abstract: The self-adaptive robot's navigation and path planning is one of the most important research issues for the intelligent robots in industry. The correct direction and destination for the intelligent mobile robot is regarded that the robot can arrive in the desired destination with an accurate direction. This paper proposes the mobile robot route planning algorithm using two fuzzy logic controllers. The first controller is designed as the path planning for mobile robot. The second one is used for avoiding any obstacles to achieve the optimal route by switching over the controller output status. Therefore, the mobile robot can move toward the desired target with accurate direction successfully. In the proposed system, the ultrasonic sensor is employed for recognizing the obstacle and detecting the distance between them. Also, the laser navigation system (NAV 200) is used to implement the navigation function. Accordingly, the mobile robot is capable of adapting to a complicated and unknown changing environment. The experimental results confirm that the error of the destination axle (X and Y) does not exceed plusmn7cm, and the direction angle error is limited within plusmn10deg.

Abstract: This paper addresses an efficient the vision based motion estimation method of a humanoid robot for the ego-motion compensation using type-2 fuzzy sets. A humanoid robot should have the ability to autonomously recognize its surroundings and to make right decisions under unknown environment. To enable a humanoid robot to do this, ego-motion compensation for a humanoid robot is mandatory. Therefore, we suggest the ego-motion estimation method so that the errors of the environment recognition caused by the ego-motion of a humanoid robot are eliminated. This method uses the disparity map obtained from the stereo-vision and can be divided into three parts - segmentation, feature extraction, estimation. In the segmentation part, a novel type-2 fuzzy sets based segmentation method to extract the objects is used. In the feature extraction module, features are extracted by the wavelet level-set transform. Moreover, least square ellipse approximation is used in the estimation part to calculate the displacement for the rotation and translation between image sequences. From the results of experiments, we can know that the proposed method can be applied to a humanoid robot effectively.

Abstract: This paper proposes a position and posture control method of the 6 DOF arm of the humanoid robot by linear visual servoing. It is based on the linear approximation of the forward kinematics which has a similar kinematic structure as a human being. Forward kinematics is the transformation from joint space to binocular visual space. Pseudo inverse matrix of the 3 linear approximation matrices of the 3 points makes it possible to realize position and posture control of 6 DOF arm by linear visual servoing. It is very robust to calibration error of camera angles, because it uses neither camera angles nor joint angles to calculate feedback command. Furthermore, the amount of calculation is very small compared to the conventional visual servoing schemes. Although the conventional 6 DOF arm control methods based on pseudo inverse matrix need non-linear complex calculation using joint angle, the proposed method does not need it. Simulation results are presented to demonstrate the effectiveness of the proposed method.

It is shown that the proposed SigmaDelta_CC_VSI reduces the harmonics amplitude variations of the unfiltered voltage. Therefore, it reduces the electromagnetic interference (EMI) problems.

Abstract: This paper analyzes the harmonic characteristics of diode rectifier with a large smoothing DC capacitor, interprets why shunt active power filter (SAPF) is not suitable for compensation voltage-type harmonic, and reveals the reason why the load peak current is enlarged at the same condition by using the subsection resonance mechanism. Furthermore, two-type methods are proposed to deal with the problems by this paper, i.e. to modify the topology/parameters so as to change the resonant frequency of the system; while the other is to improve and change SAPF's compensation bandwidth to be a selective or limited one. Both of them can suppress the harmonic current effectively and guarantee the load-side current without significant enlargement. Simulation results validate the feasibility of the schemes proposed by this paper.

Abstract: Shunt active power filter (SAPF) is suitable to compensate current-type harmonics caused by nonlinear load, but high compensation precision is difficult to be obtained due to very high slew rate of harmonic current, output impendence of voltage source converter (VSC) and control loop phase lag. LCL-filter with high attenuation ratio and small LC parameters is appropriate to be used as output filter considering the mentioned reasons. However, LCL-filter, as a third-order resonant circuit itself, is difficult to be stable. This paper proposes a novel control strategy for shunt active power filter with a LCL output switching filter. It integrates an outer loop of grid-side filter current regulator and an inner control loop of capacitor current feedback, which essentially imitates an active damper or a virtual resistor. Based on this double-loop control scheme, the SAPF can dramatically improve its efficiency and high quality steady-state grid current waveform and fast-dynamic response can be obtained even under the case of serious distorted grid voltage. Analysis and simulation results validate the correctness and feasibility of the proposed control strategy.

Abstract: Search patterns and the center-biased characteristics of motion vector distribution have large impact on both searching speed and quality of block motion estimation. In this paper, we propose a new cross-hexagon search algorithm (NCHEXS) using two cross-shaped search patterns as the first two initial steps and large/small hexagon-shaped patterns as the subsequent steps for fast block motion estimation (BME). NCHEXS employs halfway stop technique to achieve significant speedup on sequences with stationary and quasi-stationary blocks. To further reduce computational complexity, NCHEXS employs modified partial distortion criterion (MPDC). Experimental results indicate that the improvements of NCHEXS over hexagon search (HEXS) and cross-diamond search (CDS) can save 45% and 28% of search points while keep similar PSNR, and NCHEXS provides faster searching speed and smaller distortion than other popular fast block-matching motion estimation algorithms.

Abstract: Recently, vein pattern biometrics has attracted increasing interest from both research and industrial communities. The properties of uniqueness, stability and strong immunity to forgery of the vein patterns would make a potentially good biometric trait offer secure and reliable features for person identity verification. In this paper, a novel approach for personal verification by analyzing the face patterns formed by thermal imaging is presented. A new feature set is proposed to represent the thermal face: the bifurcation points of the thermal pattern and the geographical gravity center of the thermal face region. We proposed to use the Modified Hausdorff Distance to measure the similarity between two feature vectors of the thermal face. The work in this paper shows that the thermal face patterns can provide a reasonable level of discriminating power, and has the potential to be used in the context of biometric applications especially when used in conjunction with other biometric modals.

Abstract: The traditional automatic smart image surveillance system can usually be used in the environment with still background. That is, the background image must not contain the moving objects. If there is waving ocean, waving tree, floating cloud, or raining in the background image, the traditional methods do not work well. In order to improve this problem, a new motion detection method based on the theory of entropy and combined a multi-periods sigma-delta background estimation algorithm is developed in this paper. Based on the theory of moving average, a moving thresholding method is designed in this paper to obtain a sequence of alarm announcements. Experiments are carried out for some samples with dynamic backgrounds to demonstrate the computational advantage of the proposed method.

Abstract: Biometric recognition is emerging as a powerful means for automatically recognizing a person's identity with a higher reliability. Especially, multimodal biometric fusion techniques have received a lot of attention and interest in recent years. To improve the recognition rate of the singlemodal biometric system and to solve the small samples recognition problem, a multimodal biometric recognition approach based on pixel level fusion is originally proposed in this paper. We use two kinds of biometric techniques: palmprint recognition and face recognition. Firstly, all image samples are normalized and decomposed using nonsubsampled contourlet transform. Then we combine the normalized nonsubsampled contourlet-transformed face and palmprint features at the pixel fusion level. At last, the KNN classifiers are used to determine the final biometric classification. and biometric recognition results will be obtained. The experiments are performed on the two well-known databases: CVL database and PolyU palmprint database. We only use one sample of every class as the training sample in the experiments. The experimental results indicate that the proposed approach has better performance than singlemodal solution. and the proposed approach can effectively extract the detailed feature information of the biometric images.

Abstract: In extensive facilities such as port facilities, chemical plants, and power stations, it is important to detect a fire early and certainly. The purpose of this paper is to present a new smoke detection method in open areas, as smoke is considered as a significant signal of the fire. It is assumed that the camera monitoring the scene of the open area is stationary. Since smoke does not keep stationary shape or image features like edges, it is difficult apply ordinal image processing techniques such as the edge or contour detection directly. In this paper, we propose a novel method of the smoke detection in an image sequence, in which we combines the several images techniques to detect smoke. We apply it to images of open areas under general environmental conditions. First, moving objects are detected from gray.scale image sequences, and then the noise is removed with the image binarization and the morphological operation. Furthermore, since the smoke pattern must be examined, the smoke feature is extracted with the texture analysis. Then, to obtain the final result of the proposed method, we discussed the properties of the proposed features as the time series data.

Abstract: A novel image encryption technique is proposed associated with the generalized Hilbert transform in this paper. Two schemes of this technique are presented in generating real encrypted image and recovering the original image. The encrypted image is real-valued without data expanding, which can benefit the digital processing of images by electronic computers where speed of computation is important. The angles of the 2-D fractional Fourier transform, the phase of the fractional Hilbert transform and the pixel permutation matrix are as keys in the proposed method, which can improve the security of the image encryption. The mean square error between the decrypted and original real image is evaluated; and the robustness with respect to the blind encryption is performed. Simulation results show the validity of the proposed technique.

Abstract: Recently, video lossless compression has been developed for applying it to digital cinema, video archiving of contents, etc. Video lossless compression is important in image processing problem since a large image requires a large amount of storage space. The purpose of this paper is to enhance the predictor used for the lossless compression of video. In this paper, we propose the 3-dimensional predictor for the effective prediction. In addition, the three-dimensional spatio-temporal gradient is adopted to improve the conventional image compression methods such as GAP, MED which are two-dimensional predictions based on horizontal and vertical gradients. The spatio-temporal gradient is a spatial data resulted from the projection of triangular prism composed of the neighborhood pixels. From the experimental results compared with the previous prediction methods, we confirmed that the prediction using proposed method is more efficient.

Abstract: Reinforcement learning (RL) is a popular learning paradigm to adaptive learning control of nonlinear systems, and is able to work without an explicit model. However, learning from scratch, i.e., without any a priori knowledge, is a daunting undertaking, which results in long training time and instability of learning process with large continuous state space. For physical systems, one must consider that the design of controller is very rarely a tabula rasa: some approximate mathematical model of the system is always available. In this paper, our focus is on control applications wherein the system to be controlled is a physical system. We can always obtain at least an approximate mathematical model of the plant to be controlled. We propose a method for hybridization of model-based approach with RL, which is the right solution for such control problems. The superiority of proposed hybrid approach has been established through simulation experiments on a cart-pole balance bench mark problem, comparing it with model-free RL system. We have used fuzzy inference system for function approximation; it can deal with continuous action space in Q-learning. Comparison with other function approximators has shown its superiority in terms of robustness of the controller to parameter variations in the plant.

Abstract: The introduction of microprocessor-based plant control occurred shortly before 1980 with simple single-loop controllers. This technology quickly evolved into a DCS with control processor redundancy, high-density input/output systems, and a human machine interface (HMI). Today's tank management plans are faced with intense pressure to improve storage reliability. Thereby, current business goals focus on increasing operational efficiency and overall equipment effectiveness. In support of this, a tool used to identify production loss and asset availability. Third-generation DCS employ powerful object-oriented design technology to enable efficiency improvements within daily operations and maintenance (O&M) activities. Additionally, advanced process optimization technology is added to support improvements in process efficiencies. Control system technology also now integrates several fieldbus protocols, thus enabling more flexible plant designs as well as improved data for maintenance. In this paper, the Innovative, modernization, design, integration, development and implementation of a computer-based (DCS) tank gauging system for the large tank farm is described. The complex included 37 storage tanks located at 10 different groups. Each group supports data collection on the pipeline computer located in the main control room. The new and modern tank level gauging systems incorporate Radar gauges for tanks, with transmitters for temperature and pressure. All types of these gauges offer an upgrade in performance and maintainability.

Abstract: In this paper, an adaptive robust fuzzy control scheme with a genetic algorithm (GA) is proposed to solve the path tracking problem of a wheeled mobile robot. The presented controller consists of a fuzzy basis function network (FBFN) to approximate an unknown nonlinear function of the robot dynamics with uncertainties. A genetic algorithm is employed in the fuzzy inference to optimize the fuzzy rules of FBFN. The robust term with adaptive update rules is designed to suppress the external disturbances, hence it makes the system insensitive to the noises and disturbances of the environment. The robot dynamics including the actuator dynamics is considered. The stability and the convergence of the tracking errors are guaranteed by using the Lyapunov stability theory. The validity and robustness of the proposed control scheme are demonstrated through computer simulations and experiments with a wheeled mobile robot.

Abstract: In most cases, indoor environment is unstable because of floor condition, obstacles and room noise. So, to elevate accuracy of robot position data at unstable condition, a robot navigation system needs to apply diverse sensor fusion methods. This paper presents a navigation system consisting of a MEMS based digital in-plane 3 axis IMU (inertial measurement unit), an active beacon system and an odometer to obtain more precise robot position data and to monitor robot movement in realtime. Two accelerometers and one gyroscope compensate the nonsystematic errors of an odometer and perceive collision, bounce and slippage. Besides, fusing data of an IMU and an odometer can provide robot position data when an active beacon is losing its signal. When relative robot position data is unreliable, an active beacon system provides the absolute position data of the robot. To reduce noise of input sensors signal, low-pass filter and Kalman filter are applied. The sensor data from an in-plane 3-axis IMU, an odometer and an active beacon system are combined to obtain a precise navigation system. Results from two experiments in a real environment show that accuracy of robot position is elevated and that robot position data is not lost irrespective of robot's environment.

Abstract: We propose a method by which a humanoid robot learns motion through an intuitive interface with a human. Using the proposed design tool, anyone can easily control and teach robot motion. Our intuitive interface uses images of the robot. Users handle the robot image with a computer mouse, and save each segment of motion to the memory device of the robot. Then, each segment of motion makes a sequential motion pattern. With this method, users can teach motion to the humanoid robot in any way they wish. This is a first step in developing a complete learning system for humanoid robots. If the interface method is changed to a more direct method (e.g., voice-based), the proposed system is particularly advantageous.

Abstract: As to the robot joint actuated by a pair of McKibben muscles, a CMAC neural network and PID based compound control algorithm is designed. The CMAC as a feed forward compensator realizes the reverse dynamic model of the robot joint. The PID controller realizes the feed back control in order to guarantee the stability of the system. The output of the compound controller is exerted to the robot joint. CMAC regulates its network weights by on line learning and forces the PID output to tend to zero, so that the total control action is generated by CMAC. Some simulations are done and they have proved that the compound control algorithm has good tracking performance and anti-disturbance ability. And it behaves fast responding.

Abstract: When a washing machine is rotating with the laundry in it, it tends to lean to one side. This tendency causes a serious vibration. The balance of a washing machine plays an important role in order to reduce the vibration by injecting the sand or the salt water into the balance of washing machine. The hot plate welder is used to prevent the contents from outflowing. The thermal characteristics of the hot plate and the balance have to be considered for reducing the defects in plastic welding. The hot plate welder brings about many problems that may lead to an accident. The workers are protected by the loading/unloading system for the washing machine balance in the hot plate welder. This system requires direction recognition and location information of the balance. In this paper, thermal analysis of the hot plate welder for the washing machine balance is performed. The heat source of the hot plate welder plays a really important role in welding the washing machine balance. The temperature distribution of the hot plate and that of the washing machine balance are obtained by finite element analysis. The temperature of the hot plate is measured by the infrared temperature sensor in order to find the thermal contact resistance. The thermal strain of the plastic balance is predicted by thermal-structural coupled analysis.

Abstract: In this paper, an improved Ant Colony Optimization (ACO) algorithm is proposed to solve path planning problems. These problems are to find a collision-free and optimal path from a start point to a goal point in environment of known obstacles. There are many ACO algorithms for path planning. However, it take a lot of time to get the solution and it is not to easy to obtain the optimal path every time. It is also difficult to apply to the complex and big size maps. Therefore, we study to solve these problems using the ACO algorithm improved by the path crossover scheme. The path crossover scheme is two-point crossover paths found by ants. The best path is stored and is compared with new path every time. The path crossover scheme is used at this time. When the two parts compared and exchanged, the better part updates the best path. We also propose that the pheromone update rule is modified as compared with previous our paper.

Abstract: In this paper a digitally controlled electronic ballast is presented. The ballast corresponds to the so-called universal ballasts, which are intended to operate different lamps with different power ratings without performing any change in the hardware. Thus, the ballast must incorporate some kind of circuitry so that the rated power of the connected lamp can be identified. The ballast must also adjust some of its parameters in order to supply the lamp adequately, which means: (i) as closer as possible to the nominal power and (ii) with the best efficiency. In the proposed ballast, the parameters selected to adapt the power circuit to each lamp are the switching frequency and the resonant tank inductance. The resonant tank inductance is varied by means of a magnetic regulator whose inductance can be adjusted through a dc bias current. The PSoC technology from Cypress is used to implement the control stage. Besides a microprocessor, this technology integrates in a single chip both analog and digital modules that can be programmed, thus reducing the external component count to a minimum. Experimental results from a laboratory prototype for lamp powers ranging from 15 W to 58 W are provided.

Abstract: In this paper, a low voltage vertical power MOSFET is submitted to repetitive avalanche cycles under very high current (>400A) at high temperature (>150degC). Electrical characteristics such as BVDSS, IGSS, IDSS, VF, VGSth and RDSon are systematically tested along cycling. After a large number of avalanche pulses well above products requirements measurements show that RDSon decreases with the number of avalanche cycles whereas other parameters stay constant. With a simple model of RDSon measurement and new measurements such as the resistance of the metallization between two bonding wires we can connect this unexpected drop of RDSon measurement to MOSFET source electrode evolution.

Abstract: Digital control has been widely used in power electronics and its sampling rate is important to the control precision. Generally, faster the sampling rate is, closer the digital control is to that of its analog/original antetype. However, in most power electronics system, the sampling rate is commonly once or twice of the PWM switching frequency, which is vital for switching losses. This coupled relationship may result in conflict between high digitalized resolution and high efficiency, especially for high power applications. Multi-sampling technology is to sample the signal many times in one PWM period. Therefore, it doesn't need to increase the switching speed proportionally while fastening the sampling rate. This paper adopts the multi-sampling in an active power filter (APF) application. A logic method to deal with the problem during implementation due to the nature of digital controller is first proposed. Principle and implementation of this technology is discussed in detail. Analysis and experiment results show that the high compensation performance and low switching loss can be both achieved using the multisampling method.

It is revealed that the algorithm makes filter operation more stable in the case of source voltage deviations in comparison with pq method.

In the physical system, chaotic behaviors of the system are reduced. The fixed point on each period is calculated by averaging theory.

Abstract: A curve-shape piezoelectric unimorph is used for energy harvest. Deformation of the unimorph will gain electricity via piezoelectric direct effect. In this study, a cantilever unimorph encountered with external force at various vibration frequencies to generate electricity and save into a storage circuitry is investigated. Modeling of the unimorph and storage circuitry is derived. The analytical computation and experimental result are in a good agreement. Both outcomes verify that vibration frequency nearer the resonant frequency will gain more energy and the load resistance of a RC storage circuitry matching the equivalent impedance of piezoelectric ceramics will gain maximum storage energy. Efficiency of electromechanical conversion and energy storage is examined. As compared to other previous works using piezoelectric ceramics, the curve shape unimorph performs better. In experiment, for instance, by using a load resistor of 3 kOmega ideally equal to the impedance of ceramics and an arbitrarily chosen capacitor of 470 muF at vibration frequency of 135.59 Hz for 25 seconds, electric power of 48 mW is obtained and electromechanical efficiency of about 18.49% is achieved.

Abstract: The problem of complexity is here addressed by defining an upper bound for the number of the hidden layer's neurons. This majorant is evaluated by applying a singular value decomposition to the contaminated oblique subspace projection of the row space of future outputs into the past inputs-outputs row space, along the future inputs row space. Full rank projections are dealt with by i) computing the number of dominant singular values, on the basis of a threshold related to the Euclidean norm of an artificial error matrix and ii) finding the argument of minimizing the singular value criterion. Results on a benchmark three-tank system demonstrate the effectiveness of the proposed methodology.

Abstract: This paper presents a traffic controller modeled with Controlled state machine Petri nets to avoid temporary forbidden states. From the introduction of the forbidden states avoidance problem, forbidden states have been treated as a finite set of places with a specific marking. We divide the set of forbidden states in two, and introduce a new class with a temporary existence to represent more faithfully the behavior of some systems; the set of temporary forbidden states changes with the time, increasing and decreasing at a maximum and minimum size. The main problem we tackle is how to construct the traffic controller to restrict the behavior of the plant and avoid any class of forbidden states. A secondary problem is to reduce the size of the vectors of admissible control by using a smaller number of control places. At the end we present the model of the traffic controller and the simulation results.

We validated the pedestrian-counting system on a pedestrian dataset, and this analysis indicates that the proposed KPNN-type classifier provides good results.

Abstract: The output power fluctuation of renewable energy power plants such as wind turbine generator and photovoltaic system result in frequency deviation and terminal voltage fluctuation.

Abstract: This paper presents the design and construction of a current pulse power supply used for Micro-arc Oxidation (MAO), which is a novel technology capable of depositing ceramic coatings on the surface of valve metal and their alloys. The load of MAO changes acutely during oxidation process and the load transfers from capacitive characteristic to resistant characteristic. So the current pulse power supply is more suitable for MAO than the voltage pulse power supply, which is commercially available. A double switch flyback converter is incorporated into the current pulse power supply because it is capable of outputting the current pulse with a steep front edge by using the coupling inductance and energy can flow back to the power system through energy feedback channel. The control system of the current pulse power supply uses peak current control to regulate pulse energy and ensure that the energy of each pulse is uniform even though input voltage fluctuates. Frequency auto-adjustment control is used to maintain the power supply works in Critical-DCM or DCM mode to satisfy the load demand. A prototype with a peak electrical power up to 2MW, which is made up of ten units, has been constructed and tested. The pulses have a repetition rate up to 4 kHz. The experimental results show that the current pulse power supply improves efficiency of energy.

Abstract: To overcome the voltage regulation difficulty of permanent-magnet synchronous machine (PMSM), a hybrid excitation synchronous machine (HESM) with the radial structure of magnetic shunting type was designed. The magnetic shunting was exploited to adjust the air-gap magnetic field of the HESM by adjusting excitation current. The paper describes the machine's structure and principle. The concepts of the magnetic shunting point, the magnetic non-shunting point and the load balanced point were discussed. The air gap flux at magnetic shunting point and the magnetic non-shunting point were precise analyzed. The two-dimensional finite-element method (FEM) was exploited to count the positions of magnetic shunting point, the magnetic non-shunting point and the load balanced point. The theoretical analysis and experimental results show that the air gap flux of machine is lowest at magnetic shunting point and the air gap flux of machine is biggest at magnetic non-shunting point. The output voltage of machine can be kept constant by adjusting the excitation current when the power factor and the load changes.

Abstract: With the development of techniques, robots are getting smaller, and the number of robots needed for application is greater and greater. How to coordinate large number of autonomous robots through local interactions has becoming an important research issue in robot community.

Abstract: Minimally invasive surgery (MIS) robot is made like a long cylinder with small diameter that can fit through a small incision thus decreasing the amount of healthy tissue damaged. Because of the shape of the surgical robot, the cable-driven mechanism is using to the robot. However this is a highly nonlinear system so the performance of the system is not so good. This paper applied a robust motion control algorithm. The algorithm uses partial state feedback for a class of nonlinear systems with modeling uncertainties and external disturbances. The major contribution is the design of a robust observer for the state and the perturbation of the instrument of the surgical robot, which is combined with a variable structure controller (VSC). The combination of controller and observer provides the robust routine called sliding mode control with sliding perturbation observer (SMCSPO). The control performance of the proposed algorithm is evaluated by the simulation and experiment to apply to a two-degree-of-freedom (DOF) robot arm. The results showed high accuracy and good performance.

Abstract: In this paper we describe the first industrial prototype to characterize automatically the headlamp beam properties using computer vision. The European commission for transportation provides strict regulations that have to be fulfilled as far as headlamp orientations, luminous and geometrical beam properties are concerned. To test the headlamps, the test system has to be properly aligned to the vehicle in order that the measures achieved on brightness and geometrical beam profile can be reliable. The system we present is composed of two integral subsystems. The first consists of a fixed stereo vision system capable of estimating automatically, in real time and with a very high accuracy, the longitudinal axis of the vehicle while it is approaching the stereo rig. The outcome is used to accurately align the second subsystem with respect to the vehicle. This subsystem is composed of a classic optical projection system endowed with a CCD camera used to perform automatically radiometric and geometric assessments of the beam projected by the headlamps. Experiments carried out for both the subsystems prove how the high accuracy achieved by our method makes the prototype compliant with current regulations. It is worth remarking that the technology employed is low cost, thus making our approach suitable for commercial headlight tester.

Abstract: The dissolved oxygen is one of important factors to evaluate the quality of water. Currently, various aeration and oxygenation devices have been developed for increasing its oxygen concentrations in water. However, the operations of those devices usually depend on the human operation with experience. In this study, we have developed a PC-based virtual instrument (VI) system using LabVIEW, which can monitor and control the dissolved oxygen (DO) concentration automatically. Via the Internet, a nearby PC (server) of the system can collect real-time DO data from different multi-locations and transmit it to another remote PC (client) for online analysis, monitoring and control. The DO history from remote locations can be also recorded and tracked in the data base. Further, the proposed system has been successfully tested using the model aquafarm, showing an effective and reliable performance. The experimental results showed that the proposed system is capable of reducing the business costs in term of automation mechanism, high efficiency and low electricity consumption.

Abstract: An efficient hybrid distributed genetic algorithm is proposed to determine the proper number and locations of wind turbines in large wind farms. The objective of this optimal process is to find a solution that maximizes the annual profit obtained from a wind farm. It is well-known that genetic algorithms are good for global searches, but are weak for local searches. To improve the performance of finding the optimal solution in a large search space, the hybrid methodology combines a distributed genetic algorithm and steepest ascent hill-climbing local search algorithms. The hill-climbing algorithm provides a powerful strategy for searching the local optimal solution by exploring the neighborhood of the current state. In this paper, the hill-climbing algorithm is further enhanced by a heuristic method to reduce the execution time for finding the optimal value. Test results show that this proposed hybrid distributed genetic algorithm adequately demonstrates its effectiveness in solution quality and execution time.

To automatically optimize the identification rate, we need more outliers. Due to this reason, we utilize boundary value in any two dimensions randomly to generalize new outliers. At the last, we use three benchmark data sets: iris, wine, and balance-scale data base to validate the approach in this research has better classification result and faster performance.

Abstract: This paper describes a proposed spreading method to improve the bit error rate (BER) and user capacity in WCDMA system. The method is applied to the system up-link. The spreading process includes a new proposed random matrix constructed using the Walsh code generator, called randmat spreading code generator. Conventionally, the selection of the Walsh seed is highly dependable on the spreading factor (SF) of the system. This spreading factor has to be in the power of 2. However, by carefully selecting a variable n, to result in SF-n for the input seed to the Walsh code, our simulation results show that the BER can improve dramatically. The proposed multi-level modulation method could also increase the data rate and user capacity of the WCDMA system. To test the functionality of our proposed spreading method, we use a simulation model using MATLAB that is close to the behavior of a mobile station as specified in the WCDMA standards, specifically ETSI TS 125.211 and ETSI TS125.213.

Abstract: In this paper, we present the automatic real time stereo tracking algorithm we devised to derive the 3D orientation of the longitudinal axis of a vehicle by recovering its trajectory during a motion sequence. An accurate identification of vehicle's longitudinal axis is required in automotive applications where measurements achieved by testing apparatus must be in compliance with regulations. Usually, these systems are made of ensembles of sensors or are invasive, needing fiducial markers placed on the vehicle being tracked. Our method is fully automatic, non invasive and employs common CCD technology to recover 3D vehicle axis information by exploiting patterns natively present on vehicles. The experiments carried out using different orientation angles show an extremely high accuracy that is even compliant with regulations. Accordingly, we can state that this is the first fully automatic system that uses stereo technology to achieve in real time such an accuracy regarding vehicle's 3D orientation without exploiting any prior model.

Also the number of total artificial muscles for upper limb( one arm) is 12 where 6 artificial muscles are arranged in each arm. Using a simple proportional control law, the action controls from stand up position to sit down position on a chair and from the sit down position on the chair to the stand up position have been achieved by controlling 24 artificial muscles of lower limes of the robot simultaneously. Also, the action controls for various movements have been achieved by controlling 6 artificial muscles of upper limb(arm) of the robot simultaneously. By combing the upper limb to lower limb, a complete soft humanoid robot with artificial muscles will be constructed. Also, a consideration how to construct other actions such as walking, etc. for the soft humanoid robot is given briefly. This paper gives an idea for constructing different type of soft humanoid robots with artificial muscles in future.

Abstract: A smart 3D vision sensor system has been developed. This system uses Fiber grating (FG) based 3D vision sensor. The sensor system encodes the space coarsely by using limited number of geometrically interrelated 2D laser spots generated through two perpendicularly overlaid layers of FGs and projected on a targeted scene. The reflected spots and specially the disturbed due to the presence of an object or a person play an essential role in detecting targets. The author developed zone-based strategy to enable person detection within any of the zones, track the transitional movement between zones and use inter-zones relation to conclude human behavioral status. This approach has the advantage of reducing significantly the computation time of 3D information that is required for real time tracking and monitoring of human movement. The system has been implemented and this paper presents its operational characteristics. The developed tracking strategy is introduced with its application to monitor the behavior of a person and to help a mobile robot to detect obstacles.

Abstract: Plug-in hybrid electric vehicles (PHEVs) involve the use of larger battery packs and larger electric drivetrain components than regular HEVs. The control and management of the vehicular power electronics and energy storage systems are therefore more complicated and more challenging than those in conventional HEVs. This tutorial will explore the different design and control requirements and challenges of PHEV drivetrain components. The tutorial will cover topics such as PHEV topology, control, design, performance optimization, battery management, battery cell balancing, battery life extension, and cold weather performance enhancement. Vehicle to grid (V2G) concepts will be discussed along with the system requirements and impact of PHEV on the power grid. Some OEM and aftermarket PHEVs, such as the Chrysler Aspen PHEV and Prius PHEV will be used as case studies.

Abstract: In the area of drives and motion control sensors are key components and determine the quality of the complete system. Therefore, design engineers should have a thorough knowledge of the properties and characteristics of each sensor type. This tutorial deals with the sensors for current, position and acceleration as they are the most important control components in drive systems. In a systematical way, their principles of working, their properties and limitations as well as the necessary interfaces and signal processing are presented. Accuracy and resolution of the sensors are important issues in the design and are analyzed in the context of the signal processing of each variable. An overview of the state of the art of sensorless (i. e. encoderless) schemes and their advantages and disadvantages with reference to the actual industrial requirements is given. The two main solutions, the fundamental model approach and the signal injection solution are explained and compared.
