摘要/Abstract

摘要： 针对绕组分段永磁直线同步电机(WS-PMLSM)参数变化和负载扰动问题,设计一种基于预设性能的指令滤波滑模变结构反推控制器(PPSC)。给出绕组分段永磁直线同步电机的数学模型,使用反推法设计控制器,对于设计控制器中的微分膨胀问题,使用指令滤波解决,并补偿指令滤波误差。为了增强系统动态性能和鲁棒性,引入滑模变结构方法。该控制器与传统的PID控制器进行对比,仿真结果表明,该控制器有更好的鲁棒性。

Abstract: In order to deal with the problem of parameter change and load disturbance of winding segmented permanent magnet linear synchronous motor (WS-PMLSM), a sliding backstepping controller based on prescribed performance was designed. The mathematical model of the WS-PMLSM was given. The backstepping method was used to design the controller, meanwhile, using the command filter to deal with the differential expansion in traditional backstepping, and compensate the instructions filtering error. In order to enhance the dynamic performance and robustness of the system,sliding control was introduced. The designed controller was compared with the traditional PID controller. Simulation results showed that the proposed controller has better robustness.

Key words: winding segmented permanent magnet linear synchronous motor (WS-PMLSM), sliding, prescribed performance, command filter
