摘　　要：永磁同步电机广泛应用于工业控制系统,其高效稳定的性能备受青睐。研究采用基于新型趋近率滑模观测器的控制方法,通过滑模控制和低通滤波以及卡尔曼滤波的结合,改善系统的动态性能和鲁棒性。实验结果表明,新型滑模控制器具有最快的初始响应时间,仅为0.04秒,比传统滑模控制器和PI控制器快,新型滑模控制器的超调最小,仅为1%,远优于PI控制器的15%和传统滑模控制器的2%。在稳定时间方面,新型滑模控制器在0.08 s内达到稳定。研究结果表明,新型滑模观测器方法有效提升了永磁同步电机的控制性能,为永磁同步电机的控制提供了理论支持。Permanent magnet synchronous motors are widely used in industrial control systems,and their efficient and stable performance is highly favored.The study adopts a control method based on a novel approach rate sliding mode observer,which improves the dynamic performance and robustness of the system through a combination of sliding mode control,low-pass filtering,and Kalman filtering.The experimental results show that the new sliding mode controller has the fastest initial response time,only 0.04 seconds,which is faster than traditional sliding mode controllers and PI controllers.The overshoot of the new sliding mode controller is the smallest,only 1%,which is much better than 15% of PI controllers and 2% of traditional sliding mode controllers.In terms of stability time,the new sliding mode controller reaches stability within 0.08 seconds.The results show that the new sliding mode observer method effectively improves the control performance of permanent magnet synchronous motors and provides theoretical support for the control of permanent magnet synchronous motors.
