摘 要: 对感应电机提出了一种新颖滑动模控制方法:在内环采用具有扰动补偿的滑动模解耦,在外环采用PI控制器进行速度控制.将一种简单而新颖的方法用于估算感应电机的扰动信号.仿真结果证实具有扰动补偿的新型滑动模控制系统具有更好的解耦性能、快速动态响应和更强的鲁棒性. This paper proposes a novel sliding mode control methods for induction motor drives:the application of sliding mode decouple with perturbation compensation in the inner loop and of speed control by PI controller in the outer loop. A new approach is introduced to determine a system perturbation signal from the dynamics of the sliding mode.Simulation has showed that the system has more robustness and good tracking performance.
