摘要 为了研究一类不确定带有未知扰动的非线性严格反馈系统的自适应模糊跟踪控制问题.文中通过模糊逻辑系统的逼近特性和Backstepping技术构造了一个新的自适应模糊跟踪控制器.该控制器保证闭环系统的所有信号半全局一致有界,并且跟踪误差收敛到原点的一个任意小邻域内. The paper studies adaptive fuzzy tracking control for a class of uncertain nonlinear strict feedback system with unknown disturbances. A new adaptive fuzzy "tracking controller is constructed by applying "the approximation property of "the fuzzy logic system and "the Backstepping "technique. The fuzzy controller can guarantee that all "the signals in "the closed-loop system are semi-globally uniformly bounded and "the "tracking error converges to an arbitrarily small neighborhood of "the origin.
