摘要
转矩波动是开关磁阻电动机较为突出的问题。在对开关磁阻电动机转矩模型分析的基础上,提出了一种控制策略用于解决换相过程中转矩平滑过渡的问题,详细讨论了该控制策略的一种在线控制方案。理论分析表明该方法能减小转矩波动,且效果较好;通过对12/4极三相开关磁阻电动机的仿真和实验研究,验证了所提方案的可行性。
One of t he major problem of switched reluctance motor (SRM) is torque ripple. In order to solve the smooth transition of torque in the process of commutation, a new control strategy is presented in this paper on the basis of torque model. An online control scheme of the strategy is discussed in detail. Theoretical analysis, simulation and experimental results of a SRM (12/4) show that the control system can effectively reduce the torque ripple.
