摘要
电励磁双凸极电机的传统标准角控制方法,在换相时容易产生负转矩,存在转矩脉动大的缺点;三状态提前角度控制方法,解决了电机在高速工作时的转矩小的不足,但也增大了转矩脉动。通过分析两种控制方法的优缺点,结合传统电机成熟的控制方法,提出了一种应用于电励磁双凸极电机的六状态优化提前角度控制策略,并推导出该控制策略下的最优提前角度。通过仿真和实验验证,该优化策略可以有效减小转矩脉动,并增加电机的转矩,提高了该电机的起动性能。
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 op- timized advance angle control strategy is proposed through the analysis of the merits and shortcomings of the two control methods, and the traditional motorrs mature control method. Then the optimal ad- vance angle of control strategy is deduced. Simulation and experimental results show that the new strat- egy can reduce the torque ripple, increase the torque and improve the starting performance of the motor.
