针对一类未知非线性系统，考虑系统状态不完全可测的情况，利用Lyapunov 综合方法设计了一种基于高增益观测器的模糊鲁棒自适应输出反馈控制器，并证明在一定条件下，所设计的输出反馈控制器能获得状态反馈控制器的性能。关键词 非线性系统，模糊控制，鲁棒控制，高增益观测器Abstract: Based on the Lyapunov synthesis approach and a high-gain observer, a fuzzy robust adaptive output feedback control scheme for a class of unknown nonlinear systems, which states are not assumed to be measurable, is presented. It is proved that by a certain condition, the proposed output feedback controller can recover the property of the state feedback controller.Key words: Nonlinear systems; fuzzy control; robust control; high-gain observer
