摘　　要：针对一类具有严格反馈形式的非仿射非线性受扰系统,提出了基于backstepping方法的自适应模糊控制.该算法仅要求模糊逻辑系统逼近误差范数有界,引入监督控制补偿系统逼近误差和外界干扰,保证闭环系统所有信号一致有界,跟踪误差一致渐近稳定.将Rssle混沌系统作为仿真对象,仿真结果表明了该方法的有效性.A robust adaptive fuzzy control scheme is presented for a class of strict-feedback nonaffine nonlinear systems with external disturbances based on backstepping approach. The proposed approach is only requires the approximation errors of fuzzy systems norm-bounded, and an additional adaptive term is employed to compensation approximation errors and disturbances. The designed scheme guarantees that all the signals in the closed-loop system are bounded and the tracking error is uniformly asymptotically stable. Rossler chaotic system is presented to illustrate the feasibility and effectiveness of the proposed control technique.
