[IEEE 2018 IEEE Industry Applications Society Annual Meeting (IAS) - Portland, OR, USA (2018.9.23-2018.9.27)] 2018 IEEE Industry Applications Society Annual Meeting (IAS) - Performance Based Design of IMD for Single Stage PV Fed Water Pumping
摘要： This paper presents an improved designed induction motor, used for photovoltaic (PV) array fed water pumping system. The overall system is designed without a mechanical sensor to reduce both cost and complexity with simultaneous assurance of optimum power utilization of a PV array. The proposed system consists of an induction motor operated water pump, controlled by field-oriented control (FOC) with artificial neural network (ANN) current control technique. The MPPT (Maximum Power Point Tracking) as well as DC link voltage, is regulated by three-phase voltage source inverter (VSI). The estimation of motor speed eliminates the use of mechanical sensor and makes the system cheaper and robust. A new robust speed adaptive algorithm is presented, which is less dependent on parameters. A detailed study of various factors affecting the efficiency of the motor, is given to improve the behavior of the induction motor drive (IMD) for water pumping. The designed motor is tested on the developed prototype in the laboratory and its suitability is judged through various results under steady state and dynamic conditions of insolation variations.

[IEEE 2018 International IEEE Conference and workshop in óbuda on Electrical and Power Engineering (CANDO-EPE) - Budapest, Hungary (2018.11.20-2018.11.21)] 2018 International IEEE Conference and Workshop in óbuda on Electrical and Power Engineering (CANDO-EPE) - Plasma ignition and current control considerations for magnetron sputtering power supplies
摘要： Physical vapor deposition processes require different types of special power supplies for the ignition and sustaining of the plasma inside the sputtering chamber. The paper identifies some requirements for the design of a pulsed DC converter. Experiments have been carried out to identify the current-voltage characteristics of the vacuum chamber with the supply of different gases, and gas mixtures in the usable pressure domain. The vacuum chamber was supplied with voltage and current impulse trains with various parameters in order to acquire relevant data regarding the gas breakdown in pulsed power mode. A power electronic converter topology and control routine has been proposed, which is suitable for plasma ignition and discharge current control. The proof of concept has been demonstrated with the help of the magnetron sputtering chamber supplied by a test circuit.

Fabrication of large scale PS monolayer colloidal crystal film by using a novel secondary self-assembly method for nanoimprint technique
摘要： In the dynamic wireless power transfering(WPT) process of electric vehicle, the charging current of the battery is affected by some factors, such as the primary coil current and the relative position of the primary and secondary coils. Moreover, due to the travel of the electric vehicle, it is difficult to establish effective feedback between the primary side and secondary side. In this case, the charging method based on the primary side and secondary side independent control is analyzed. In this paper, it shows that the PID controller is set up after modeling the transmitter and the receiver. The effectiveness of this strategy is also verified by simulation on MATLAB.

Design of Efficient Resonator-Enhanced Electro-Optic Frequency Comb Generators
摘要： This paper proposes a direct double-frequency ripple current control in a single-phase high-power fuel cell converter that can achieve low-frequency ripple-free input current without using large electrolytic capacitors. To eliminate the double-frequency ripple current disturbance introduced by the single-phase inverter load, a proportional–resonant controller is developed to achieve an extra high control gain at designed resonant frequency. This high gain can be viewed as the virtual high impedance for blocking the double-frequency ripple energy propagation from inverter load to fuel cell stack. More particularly, the proposed control system can realize the utilization of all capacitive ripple energy sources in the system by regulating all the capacitors to have large voltage swing. In addition, this voltage swing is synchronized to keep real-time balancing of the transformer primary- and secondary-side voltages. As a result, the zero-voltage-switching operation for all switching devices in the dc–dc stage can be guaranteed. The controller design guidelines are derived based on the system small-signal model. The experimental results are presented to validate the theoretical analysis and proposed technology.

摘要： State-space current control enables high dynamic performance of a three-phase grid-connected converter equipped with an LCL filter. In this paper, observer-based state-space control is designed using direct pole placement in the discrete-time domain and in grid-voltage coordinates. Analytical expressions for the controller and observer gains are derived as functions of the physical system parameters and design specifications. The connection between the physical parameters and the control algorithm enables automatic tuning. Parameter sensitivity of the control method is analyzed. The experimental results show that the resonance of the LCL filter is well damped, and the dynamic performance specified by direct pole placement is obtained for the reference tracking and grid-voltage disturbance rejection.

摘要： This paper investigates a Fuzzy Hysteresis Band Current Control technique (Fuzzy-HBCC) for a Photovoltaic active power ?lter connected at PCC to the AC grid and a non-linear load. This connection offers good bene?ts of producing PV power as well as ensuring the power quality enhancement. In order to demonstrate the ef?ciency of the proposed system command using Fuzzy-HBCC, Fuzzy Vdc controller and Fuzzy-MPPT controller; several simulation cases have been carried out under an online solar variation, and a variable/?xed ignition angle of the nonlinear load. The proposed Fuzzy band current control technique (Fuzzy-HBCC) is developed and compared by simulation, in a Matlab/Simulink environment, with an adaptive Hysteresis controller (adaptive-HBCC) and a ?xed Hysteresis controller (?xed-HBCC) which require mathematical model determination. The results show the robustness of the proposed Photovotaic active power ?lter system with a better dynamic response and signi?cant reduction in Total harmonic distortion levels even under a sudden variation of the nonlinear load and of solar irradiance.

摘要： Model predictive control (MPC) has been widely advocated as a design strategy for many aspects of industrial electronics. The methodology has been strongly promoted by some researchers but has also attracted criticism from others. In this context, the purpose of this paper is twofold. First, we show that many existing and popular control strategies, including finite set MPC and linear controllers [proportional integral, proportional resonant (PR)], can be viewed as special cases of MPC. Second, we show that the predictive control framework allows one to embellish these classical control architectures with novel features and to design new and advanced control architectures to address various challenges posed by power electronics applications. The findings of the paper are supported by a practical example of designing of a novel form of PR controller with superior tracking performance and delay compensation, confirmed via simulation and experiments.

摘要： An adaptive controller for regulating and dimming problems of LED current control is developed in this article when the LED driving system is considered as a class of unknown nonlinear discrete-time systems. The controller is designed by a Fuzzy-rules emulated network (FREN) with direct human knowledge as IF-THEN rules of the controlled plant. The online learning algorithm is established to tune all adjustable parameters of FREN with the convergence analysis. The prototyping system is constructed by using Raspberry Pi model B as a main processing unit. Experimental results validate the satisfied performance for both current regulation and dimmer applications with positive and negative slopes.
