一类相似组合大系统鲁棒控制器设计

Robust Controller Design for a Class of Large-Scale Similar Composite Systems

首先从理论上描述了两个线性控制系统间的相似性。由这类线性控制系统互联组成的具有不确定参数的非线性组合大系统仍具有某种相似结构，充分利用其相似结构信息可以设计出一种变结构鲁棒控制器。由于目前还没有针对一般非线性组合大系统的控制器设计方法，所以相似结构在一定程度上可以简化组合大系统的分析和设计。

The similarity between two linear control systems is mathematically described.Certain similarity is displayed in the large-scale composite system composed of the connected subsystems with similarity.By utilizing fully the similar information,the robust controller with variable structure can be obtained.At length,it is shown that the similar structure can simplify the analysis and design,since the uniform analysis and design method for the large-scale nonlinear composite systems are not formed as yet.
