Description
Summary:	A novel control technique is proposed to improve torque ripple in the switched reluctance motor (SRM), based on interference torque ripples (ITR) by using the destructive interference. The proposed technique can be explained by two main steps, the first step is each phase in the SRM divided into two homogeneous phases in order to control every phase separately, the second step is the implementation of an intelligent strategy that allows to processing a reference torque in order to give two-reference torques in case of antagonism. The reference torque is produced from a speed controller to maintain the desired speed, and the two-reference torques are controlled by hysteresis controller for obtaining the destructive interference. The proposed control has been applied in a nonlinear finite elements method modeling of an 8/6 SRM. All results are analyzed and compared to these given in case of conventional control methods. The obtained results confirm and show the effectiveness of the proposed technique based on ITR.
