Abstract: This paper presents a new control scheme to implement the torque ripple minimization in switched reluctance motor drives. The proposed scheme uses the nonlinear torque sharing function in which two active phases contribute the torque during phase commutation and the torque at other time is produced by an active phase. The flux linkage controller with the hysteresis chopping is employed to trace the flux linkage reference computed from the torque sharing function. The simulations on a four-phase switched reluctance motor drive demonstrate that the proposed control scheme can be used to well implement the torque ripple minimization. Comparing with conventional current controllers, the limit on the proposed flux controller is easily determined and the saturation of the flux linkage controller may be avoided.
