Abstract
This paper investigates the problem of high torque ripple in current controlled switched reluctance motor (SRM) drives. Torque ripple reduction bellow the base speed of the motor is studied through adjustment of both turn-on and turnoff angles. A multiobjective optimization function is used to determine the proper turn-off angle in each operation point. Based on a proposed approach on intersecting of the consecutive phase currents, the turn-on angle is properly adjusted. The proposed method is quite easy to implement and does not need the exact parameters of the motor to run. Simulations and comparisons are also presented to validate the proposed control scheme.
