摘要
由于非线性振动系统的非线性本质，基于传统控制理论的线性控制器用于非线性振动控制效果不佳。本文针对非线性振动系统提出了一种模糊自适应滑模控制方案。设计中用模糊逻辑系统逼近未知的非线性函数，基于滑模原理及Ｌｙａｐｕｎｏｖ函数方法给出了该控制系统的稳定性分析。并就典型的ＶａｎＤｅｌＰｏｌ形式的非线性强迫振动系统进行了控制仿真研究。
Because of the nonlinear foundation of nonlinear vibration systems, the linear controller used in nonlinear vibration active control based on traditional control theory can not work very effectively. In this paper, an adaptive fuzzy sliding mode control scheme is proposed for nonlinear vibration systems. In the design, the fuzzy logic system is used to approximate the unknown nonlinear function, and the stability of proposed control scheme is proved based on the principle of sliding mode control and Lyapunov function method. The numerical simulation shows that the scheme presented is a very efficient method for controlling nonlinear vibration system.
