| 摘 要： | 以磁浮开关磁阻电机轴向力为对象,研究了其转子稳定悬浮的控制.根据电磁场理论,建立了轴向悬浮力数学模型,针对悬浮力控制的非线性特点,采用基于离散时间趋近率的变结构控制方案,完成了电流、位移双环控制的轴向悬浮力控制器,实现了轴向悬浮力的稳定控制,分析了实现稳定跟踪的滑动模态的存在条件,并进行了仿真分析,仿真结果验证了该控制策略的有效性.

| Abstract: | The axial force mathematical model of magnetic suspending switched reluctance motor(SRM) is analyzed.At aim of the serious nonlinear characteristic of suspending force,the double closed loops-based axial suspending force controller is designed.The sliding model variable-structure control based on discrete-time reaching law is applied to fulfill an accurate displacement tracking control.The inner current closed-loop forces the actual winding current following the desired current.Simulations are carried out,a... |
