摘　　要：本文研究了匹配结构不确定非线性相似组合大系统，给出了其可用结构相似非光滑控制器进行镇定的鲁棒控制器设计方案及镇定域的估计方法．这种控制器由线性和非线性部分组成，其中的非线性部分类似于“砰砰”控制结构，容易实现．研究表明，相似结构能够简化非线性组合大系统的分析与设计．In this paper, nonlinear uncertain composite systems with similarity are studied. It shows thatunder some conditions, the systems can be robustly stabilized by controllers with similar structure. Such controllers are composed of linear part and nonlinear parts which are of the structure similar to 'Bang-Bang'control. It is shown that the design and analyze of composite systems can be simplified by similar structure.
