Closed Loop Control of Excitation Parameters for High Speed Switched Reluctance Generator Using MATLAB/SIMULINK

Abstract

This paper presented a novel Proportional Integrator Current Chopping Control (PI-CCC) based on Switched Reluctance Generator (SRG).The fundamental principle of the PI-CCC is based on the minimization of torque ripple of the SRG. The excitation parameters for the SRG system operates at sufficiently high speed that it operates in the single pulse mode. In this paper PI-CCC based SRG modeled are simulated by using MATLAB/SIMULINK. In this model to analyze both dynamic and steady state system output its respectively, the power converter, excitation source, and loads were simulated based on SIMULINK/Sim power systems (PSB).Index Terms: Proportional Integrator Current Chopping Control (PI-CCC), Switched Reluctance Generator (SRG) IntroductionThe applications of Switched Reluctance Generator (SRG) under special environments have being increased day by day, because they have several inherent advantageous features such as rug, low cost, robustness and possible operation in high temperatures or harsh environments. These features make the SRG a candidate for applications such as aircraft engine starter/generator [1], automotive starter/generator [2], and wind turbine generators [3]. Unfortunately, SRG is a multivariable, strong-coupling and non linear system, it is very difficult to model and analyze.To analyze the operating performance of SRG, lots of modeling methods were presented. The circuit simulation program "SPICE", it has certain limitations[4]. Reference[5] uses object oriented program technique, it is very flexible, but it is difficult to actualize, because it needs the complete mathematical model of the system. The introduce some modules and M-file in MATLAB to build the nonlinear mathematical model of the magnetization curves, it is accurate, but the simulation speed is slow [6].A novel method for nonlinear modeling based on circuit simulation are built by selfdefining M-functions and basic modules SIMULINK/simulink library. The model built in this paper is very flexible and visual; its simulation speed is very fast [7]. but, The turn on and turn off angles are fixed.Control of the SRM is more complicated for generator operation than it is for motor operation. Operating as generator, the turn-on and turn-off angles control the peak phase currently jointly and severally. The control of the excitation parameters for the switched reluctance generator (SRG), where the SRG system operates at sufficiently high speed, that its operates in the single pulse mode. [8].This paper presents a novel modeling for Nonlinear Modeling and closed loop control of Excitation parameters for high speed switched reluctance generator (SRG). In this simulation model, the power inverter, excitation source, inductor model, design of each phase model, and loads are simulated only SIMULINK/Simpower system. The turn-on and turn-off angles are the two parameters through which we can control the simulation results really report the work status of the generator system and validate the applicability of the model and the proposed cont...

Controller Design for Closed Loop Speed Control of BLDC Motor

“…In the Paper [3], the performance of Induction Motor drive for direct torque and flux control using fuzzy logic and sliding mode speed control was presented and the robustness analysis in presence of parameter uncertainty and load disturbances was carried out. The authors in the paper [4] proposed a novel Proportional Integrator Current Chopping Control (PICCC) method for torque-ripple minimization of Switched Reluctance Generator in presence of load disturbances. Application of Fuzzy logic technique in speed control of doubly fed induction motor using fuzzy PI controller in presence of load torque disturbances is reported in the paper [5].…”
