In the traditional standard angle control method, negative torque and large torque ripple exist constantly in the commutation time for doubly salient electro-magnetic motor. The torque is increased by the advance angle control method at high speed, however, the torque ripple is also increased. An optimized advance angle control strategy is proposed through the analysis of the merits and shortcomings of the two control methods, and the traditional motor′s mature control method. Then the optimal advance angle of control strategy is deduced. Simulation and experimental results show that the new strategy can reduce the torque ripple, increase the torque and improve the starting performance of the motor.
