Research on SRM Control Method with Improved Torque Sharing Function
Switched reluctance motors(SRM)have the inherent disadvantage of large torque ripple.Direct instan-taneous torque control directly controls the feedback torque of the motor,which can effectively suppress torque ripple.However,the quality of its control performance largely depends on the torque distribution function.This paper proposes an improved torque sharing function,which instantaneously calculates and corrects the commutation angle of the torque sharing function with the real-time change of electromagnetic torque.To verify the proposed strategy,the paper builds a simulated model of a 3-phase 12/8-poles switched reluctance motor controlled by the proposed strate-gy,and the results show that the strategy effectively suppresses the large torque ripple under the step change of the motor load.
