摘　　要：针对一类未知非线性系统 ,提出一种输出反馈控制方法。首先在假设系统状态已知的情况下设计状态反馈控制器 ,实现跟踪性能。然后在系统状态不完全可测的情况下 ,通过设计高增益观测器对系统的状态进行估计 ,实现输出反馈控制器设计。Fuzzy indirect adaptive output feedback tracking control scheme is developed for a class of nonlinear systems. The designing process is divided into two steps. First it is supposed that all the states are available for feedback and the state feedback controller is designed. Second it is supposed that the states are not available for feedback, then output feedback controller is designed by introducing high gain obsever. It is proved that the output feedback controller can achieve the tracking performance of maximum minimum problem.

关 键 词：自适应控制 非线性系统 模糊控制 反馈控制器
