An Adaptive Fuzzy Controller for Nonlinear Vibration Systems

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.
