摘　　要：由于电力推进船舶开关磁阻电机(Switched Reluctance Motor,SRM)运行工况和负载实时变化,传统三段式调速很难通过试凑法来确定切换时刻的转速和开通角、关断角,如果选择不当将造成切换时刻转速或者转矩的波动,引起系统的不稳定。针对此问题,本文对传统三段式调速策略进行了优化,提出一种交错控制策略。最后在实验验证了该控制策略的有效性,改善了控制性能,提高了系统的稳定性。Traditional strategy of three stages cannot determine the correct speed and angle at the switching moment because of the real-time changes of the operation conditions and load of switched reluctance motor(SRM)used in ship electric propulsion system.The speed and torque fluctuation will drive the system to be unstableif the choice of the speed and angle is not appropriate.Aiming at the problem,this paper optimizes the traditional strategy of three stages and presents an interleaving control strategy.The tests show that this strategy is efficient,improve the system performance and stability.
