摘要
针对一类具有不确定性的非线性系统,提出一种模糊控制方案,控制中只利用系统输出信号和一些辅助信号。利用李亚鲁诺夫方法证明了闭环模糊控制系统全局稳定.仿真表明该控制方案可回避通常滑模控制中不可避免的颤动,且系统具有很强的鲁棒性。
A scheme of fuzzy control for a class of nonlinear systems with uncertainties is presented in this paper. Only the output signal and some auxiliary signals are used in the control scheme. By using Lyapunov method, the closed-loop fuzzy control system is proven to be globally stable. Simulation shows that the chattering phenomenon which is inherentto a sliding mode control is avoided, and the control system exhibitsstrong robustness.
