| 摘 要： | 为了减少永磁同步电机调速中的动态误差,提出了一种积分性能最优的滑模控制方法。该方法以滑模控制中的动态误差为性能指标,在此基础上建立最优切换函数,并采用最优控制理论对滑模控制器进行设计。用该方法设计的滑模控制系统,通过滑模面斜率的连续变化,能够加速系统状态变量到达滑模面的过程,极大地提高对参数摄动和外部干扰的鲁棒性。仿真结果表明,该时变滑模面控制方法使系统具有无超调、快速、稳定等优点,提高了系统的鲁棒性。

| Abstract: | In order to reduce the dynamic error in the permanent magnet synchronous motor (PMSM) speed control, a sliding mode control (SMC) method with optimal integral performance was proposed. In this method, the dynamic error in SMC was taken as the performance index. On this basis, the optimal switching function was established, and the optimal control theory was used to design the sliding mode controller. The SMC system designed by this method could speed up the process of the system state variable reaching the sliding surface by continuously changing the slope of the sliding surface, and greatly improve the robustness to parameter perturbation and external disturbance. The simulation results showed that the timevarying sliding surface control method had the advantages of no overshoot, rapidity and stability, and improved the robustness of the system. |
