Discrete-time Fuzzy Sliding Mode Control of AC. Servo System

文章针对高精度交流伺服系统 ,采用了一种新型的离散模糊滑模变结构控制策略。该方法设计简单 ,既不牺牲滑动模态的鲁棒性 ,同时又有效地减小了抖振。仿真结果表明由该离散模糊滑模变结构控制器构成的交流伺服系统 ,具有很好的快速性。

This paper proposes a novel discrete fuzzy sliding mode control scheme for high accuracy AC servo system. The controller is very easily designed and the sliding condition is easily satisfied . The system with this controller has good robustness, and the chattering on the slide module is apparently decreased. Simulation results show that AC system with the novel discrete fuzzy sliding mode control is insensitive to parameter variations and disturbances and has good fastness.
