| Abstract: | Torque ripple is a primary disadvantage of switched reluctance motor. Based on direct instantaneous torque control (DITC), this paper presents a novel method of torque ripple minimization by controlling the instantaneous torque to track the reference torque directly and combining with a torque hysteresis-controller. A complete simulation model of a 12/8 poles 3 phases switched reluctance motor on Matlab is developed in this paper. The efficiency to minimize torque ripple is tested by digital simulation and confirmed by experimental results. |
