摘　　要：永磁同步电机在参数处于特定区域时会存在混沌现象,混沌的存在将使电机性能变差。为解决这个问题,结合滑模控制原理,提出了永磁同步电机混沌运动的无抖振终端滑模控制方法。该方法通过对转速外环和dq轴电流内环控制器的设计,可以确保电机的输出转速和电流在有限的时间内到达任意给定值。控制器的内部有低通滤波环节,能有效削弱传统滑模控制产生的抖振问题。仿真结果表明,该方法控制速度快,精度高,鲁棒性好。Chaotic phenomena exists in permanent magnet synchronous motor （PMSM）when its parameters are within a certain range of value, degrading the performance of the motor drive system. Combined with sliding mode control theory, the paper proposes a chattering-free terminal sfiding mode control method to solve the problem in PMSM. The method can ensure that the motor output speed and current reaches any given value in finite time by designing the outer-loop speed controller and inner-loop d-q axis current controller. There is low-pass filter inside the controller that can effectively weaken the chattering problem caused by traditional sliding mode control. The simulation resuhs show that the control method is of high speed and precision as well as good robustness.
