Control of a 12/8 Switched Reluctance Motor with Saturation Characteristics for Light Electric Vehicle

This paper deals with the modeling and control of a three phase, low voltage switched reluctance motor (SRM) for light electric vehicle (LEV). An improved method of modeling and control of the SRM is implemented, which is fast and accurate. The flux versus current characteristics at different rotor position and torque versus rotor position for various values of currents are achieved for the SRM. The modeling is done using current and voltage measurements of a SRM and the saturation characteristics are estimated offline over MATLAB/Simulink platform. The control of SRM is implemented using asymmetric bridge converter. The switching is implemented using a hysteresis current control. Simulation results for the starting and steady state performance of the SRM are discussed in detail.
