一类不确定性非线性系统的状态反馈鲁棒自适应控制器的设计与分析

Abstract

Abstract:

In this paper, a class of nonlinear systems (1) with general uncerta inties and part unknown parameters is considered, and a robust adaptive state feedback controller is designed for tracking reference signal. The controller is r obust to the uncertainties of both the parameter and the state of the system. The global stability of the resulting closed loop system can be guaranteed and t he &epsilon tracking problem has been solved as well. The good track effect of the adaptive robust controller and the range of the admissible control for used control quantities are presented in the examples of simulation.

Key words: Uncertain nonlinear systems; , State feedback; , Robust adaptive control, Global , stability; , &epsilon, tracking
