摘　　要：研究一类不确定性有界 ,互联项满足Lipschitz条件的非线性不确定组合大系统的观测器设计和鲁棒分散镇定问题 .给出了一类鲁棒观测器的设计方法以及基于此观测器受控系统的鲁棒分散镇定方法 ,其结果不仅效果较好 (指数收敛 ) ,而且是全局性的 .最后给出一个数值例子说明结果的有效性 .In this paper, the problem of robust observer synthesis and robust decentralized stabilization for a class of rncertain nonlinear Interconnected systems subjected to Lipschitz interconnected functions and bounded uncertainties is investigated. A kind of robust observer and robust decentralized controller for the systems are presented. The proposed estimation state feedback controllers ensure that the closed loop state is globally exponentially stable. Finally, a numerical example is given to illustrate the result in the paper and simulation shows that the method is very effective.
