中文摘要:
      永磁直线同步电机(PMLSM)的推力波动与其输入电流紧密相关,为最小化电流误差,提出一种基于Park变换的旋转角度补偿算法,并在其基础上建立PMLSM双闭环滑模变结构控制(SMC)系统。针对SMC控制器引入的抖振问题和系统固有的扰动,设计扰动推力观测器。MATLAB/Simulink联合仿真证明该策略能有效地减小电流误差和电机推力波动。
英文摘要:
      The thrust fluctuation of permanent magnet linear synchronous motor (PMLSM) is closely related to it’〖KG-*2〗s input current. In order to minimize the current error, a rotation angle compensation algorithm based on Park transformation was proposed, and a PMLSM double closed loop sliding mode variable structure control (SMC) system was established based on this algorithm. For the chattering problem introduced by SMC controller and the inherent disturbance of the system, the disturbance thrust observer was designed. The MATLAB/Simulink co simulation results show that the proposed strategy can be used to effectively reduce current error and motor thrust fluctuation.
