满足互联条件相似组合大系统的鲁棒分散控制

Robust decentralized control for similar composite systems satisfying interconnection condition

研究了一类相似组合大系统。此类系统的互联项不是对称的且不满足匹配条件。为了设计出系统的分散控制器，本文提出了一种二步法设计方案，充分地利用了系统的互联项的有利作用。首先，设计出系统的假想的互联项──满足匹配条件，并利用它把系统改变成新的形式。然后，基于系统的新形式，采用常规的设计方法，设计出系统的分散控制器。此控制器确保系统二次稳定。

A class of similar composite systems is discussed, and the interconnections in suchsystems may be asymmetrical and mismatched. To make full use of the interconnections, thetwo step method is proposed to design the decentralized controllers. First step is to design unrealinterconnections to change the system into new form with matched condition, secondstep is to deign the decentralized controllers by the regular method for the new system. Thecontrollers guarantee the system quadratic stability.
