【Abstract】 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.更多还原
