【Abstract】 ne of major disadvantages of a switched reluctance motor(SRM) is torque ripple. on the basis of the confirmation of SRM structure and parameters, this paper presents a kind of control strategy to minimize SRM’s torque ripple. To express the torque ripple,the coefficient of the torque ripple is defined. The effect of different control parameters on the performance of SRM is also studied. Aiming at reducing the torque ripple,this paper selects the optimum control parameters on the basis of simulation results and gives the control strategy of a protype motor. In the end, the Performance of SRM controlled with the control strategy is analyzed.更多还原
