摘要
针对PI控制和模糊滑模变结构控制在交流调试系统中的局限性,利用它们的各自优点,采用双模态控制方法对交流异步电动机系统进行控制,得到模糊滑模变结构设计过程以及采用PI控制和模糊滑模变结构控制相结合的双模态方法运行的结果。仿真结果表明:该方法不仅解决了模态抖动问题,而且改善了系统动态特性,证明了双模态控制在交流调速系统中的应用价值。
Aiming at the limitations of PI control and fuzzy sliding mode control applied in the AC speed regulating system,this paper proposes a two-state control method for the AC speed regulating system.Both the designing process of fuzzy sliding mode controller and the simulation results of the two-state control method based on PI control and fuzzy sliding mode control are given.It is shown from simulation results that the proposed method may handle the chattering of sliding mode and improve the dynamic performance of the controlled system.
