Modeling of Switched Reluctance Motor Drive System using Matlab/Simulink for Performance Analysis of Current Controllers

Abstract

This paper deals with a new technique in modeling switched reluctance motor (SRM) drives using Matlab/Simulink. The model is solely based on Matlab/Simulink environment, i.e. using available block sets for SRM, converter, as well as current controllers design. The model is to assist in initial study for performance analysis of any algorithms including closed loop operations such as current, speed and torque controllers. The actual hardware system is represented in the model taking into account all necessary drawbacks such as the electrical time constant, the inverter switches behaviors etc. Simulation results are presented here for two SRM drives system models; one, a model that uses complete M-file scripts and second, a model that utilizes complete Matlab/Simulink blocksets.
