摘　　要：针对参数摄动、外部扰动等因素对永磁同步电机运行性能的影响,应用非光滑控制方法设计了连续的非线性位置跟踪控制器。根据李亚普诺夫稳定性理论,证明了所设计控制器能够实现闭环系统的有限时间稳定性,并通过仿真验证了控制器的有效性。对所设计的控制器进行了数值仿真,并与传统控制器进行响应性能和抗扰动性能对比。仿真结果表明,所设计的非光滑控制器可以实现电机系统有限时间内稳定,具有良好的鲁棒性和抗干扰效果。The operating performance of the control system for permanent magnet synchronous motors is often af- fected by adverse factors, such as parameter perturbation and external disturbance. A continuous nonlinear controller for permanent magnet synchronous motors is designed by using non-smooth control method. According to the Lya- punov stability theory, it is proved that the designed controller has finite-time stability. And its correctness is verified by simulation. The simulation results show that the designed non-smooth controller guarantees the finite-time stability of the motor＇ s system and has better effect of robustness and anti-interference than the conventional controllers.
