Abstract : Though rugged and simple construction makes Switched reluctance motor (SRM) a potential candidate for many industrial applications, the presence of higher torque ripple is poses a limitation to its wide spread use. This paper presents a torque ripple reduction method by using a hysteresis torque and current controller. The reference torque is derived from a speed controller and the reference current is derived from the torque controller. Since the torque is proportional to the square of the current, a substantial reduction of torque ripple is seen when the current is controlled. Simulation is done in MATLAB/Simulink platform with each controller separately and finally all the three controllers put together. © Research India Publications.
