时变滑模变结构与智能模糊结合的非线性系统控制

Nonlinear System Control Based on Time-Varying Sliding Mode and Intelligent Fuzzy Control

时变滑模变结构与智能模糊结合的非线性系统控制,先采用时变滑模变结构控制,通过设计动态滑模面,系统的任意初始状态一开始就处于系统的滑模面上,使系统对内部参数变化和外部干扰均具有全局鲁棒性。然后设计智能模糊控制器,使整个系统的鲁棒性在线调整,不仅增强了全局抗干扰能力,而且有效消除系统的抖振现象。

The nonlinear system control is proposed, control and intelligent fuzzy control. At first, a dynamic which combined the advantages of time-varying sliding mode sliding mode surface was designed to guarantee that the system was of global robustness against parameter variations and external disturbance as the state lied on the sliding surface from any arbitrary initial states. Then an intelligent fuzzy controller was used to adjust robustness property on line, and thus the system performance is much better improved and the system chatter is reduced efficiently.
