Torque Ripple Minimization of Switched Reluctance Motor and Comparison of Controllers for Electric Vehicle Applications

As SRM doesn't have permanent magnet, it is light weight motor and has constant power output capability which finds application primarily in space applications and Electric Vehicle because of high torque to weight ratio and low rotor inertia. It has small size, high efficiency, low cost. Hence, day by day Switched Reluctance Motor is becoming best alternative to DC and BLDC motors. In this paper MATLAB Simulink model is used to analyze controller performance. Selection of angle for region of operation to trigger the converter is explained here. With feasible approximations, nonlinear nature of SRM can be explained with its linear model having dynamic behavior, for the sake of simplicity and study purpose.
