摘要
针对一类高阶非线性系统提出了一种稳定的自适应模糊变结构控制方案 ,它既可以利用模糊描述信息 ,又可以利用变结构控制 .并提出了参数适应律 ,保证有关参数的有界性 ,并用李雅普诺夫方法保证了系统的全局稳定性 .
A scheme of a stable adaptive fuzzy variable control for a class of high_order nonlinear system is proposed in this paper. The scheme can incorporate the fuzzy rulers on the error between the system and model. Also the scheme can use variable control .This paper proposes adaptive laws of parameters and ensures the bound of parameters .The stability of the system is proved by the use of the Lyapunov function .This control algorithm has strong controlling capacity.
