摘　　要：首先描述了两个控制系统间的相似性概念 ,然后讨论了一类结构不确定的非线性相似组合系统的鲁棒镇定问题 .设计出一类分散控制器 ,这种控制器由线性和非线性两部分组成 .结果表明 ,相似结构确实可以简化组合系统鲁棒镇定的判据 .最后的算例和仿真表明了本文结论的有效性 .The system description with similarity is given, then robust decentralized stabilization for a class of nonlinear systems with sturcture uncertainties and similarity is discussed. A robust decentralized stabilizing controller is designed, which is composed of linear part and nonlinear part. It is shown that similar structure can simplify the analysis and design of composite systems. Moreover, the similar structures of nonlinear composite systems have the characters which can stabilize the systems.
