摘　　要：对一类不确定非线性相似组合大系统，设计出一种渐近观测器。说明了在一定条件下，相似系统存在结构相似鲁棒观测器。并通过一个数值算例说明了本文的结论及结构相似鲁棒观测器的设计方法。仿真结果表明了所得结论的有效性。In this paper, nonlinear composite systems with similarity are studied, and robust observer with similar structure for the systems is presented. It shows that under some conditions, similar systems are of observer with similar structure. Finally, an numerical example is given to illustrate the result of this paper and the method of design of similar observer. Simulation shows that our result is valid.
