A high accuracy AC servo System based on sliding mode control strategy

本文根据滑模变结构理论提出一种速度调节器的设计方法 ,并利用 Matlab5 .0进行了仿真实验 ,仿真结果表明由此构成的三闭环交流位置伺服系统具有定位无超调 ,无静差 ,响应速度快 ,鲁棒性强等优点 ,最后 ,讨论了滑模控制器各参数的选择对系统性能的影响。

This paper presents a design method of the speed regulator based on the sliding mode control theory.Subsequent simulation results under Matlab 5.0 show that it can bring better robustness, faster response, nonovershoot and higher accuracy to AC servo systems. Finally the influence of the parameters selection for the controller on the performance of the servo system is discussed.
