摘　　要：针对垂直运动永磁直线同步电动机的特点 ,通过对其力移特性分析 ,得出了电磁力角与最大推力控制策略 .该控制策略将电机的稳定控制引入到最大推力控制中 ,根据电机实际位移量的变化 ,直接控制直线电机的电磁力角 ,实现直线电机的速度控制 ,响应速度快、超调量小 ,有效地提高了永磁直线电动机垂直运输系统运行的稳定性。The control strategy of electromagnetic force angle and the maximum of thrust is obtained by considering the characteristics of permanent magnet linear synchronous motor (PMLSM) for vertical movement, and by analyzing its force-displacement properties. The stable motor control is introduced to the maximum of trust control by using this strategy. According to the real motor displacement, electromagnetic force angle of linear motor is directly controlled, and velocity control is realized either. The response speed is quick and the over-regulation is small. So the stability, credibility and running efficiency of vertical transportation system of PMLSM are improved significantly.
