摘要
针对滑模变结构控制的抖振问题,提出一种用于异步电动机矢量控制系统的积分滑模变结构速度控制方法.该方法只要求速度信号,不需要加速度信号,具有抗扰能力强的特点,而且积分作用可以显著减小速度控制的稳态误差.实验结果证实了所提方法是有效的.
A strategy of speed control for vector-controlled asynchronous motor drive system using sliding mode variable structure control with an integral action was proposed. Only speed signal is needed with no requirement of acceleration. It is characterized by robustness to disturbance and fast dynamic response. The steady error of speed control is effectively reduced by the integral action in the proposed scheme. The experimental results verify the effectiveness of the proposed method.
