摘　　要：This paper deals with the problem of decentralized robustcontrol for a class of interconnected uncertain systemswith state delays.The parameter uncertainties are un-known but norm-bounded.A new sufficient condition isobtained for each subsystem and overall system to be sta-bilizable via linear memoryless state feedback robust de-centralized controllers.The results depend on the size of the delays and are given in terms of linear matrix ine-qualities,so they are less conservative than those of delay-independent.Moreover,matching condition is not a necessary condition.Finally,an example is presented to illustrative the effectiveness of the proposed method.This paper deals with the problem of decentralized robust control for a class of interconnected uncertain systems with state delays. The parameter uncertainties are unknown but norm - bounded. A new sufficient condition is obtained for each subsystem and overall system to be sta-bilizable via linear memorylcss state feedback robust decentralized controllers. The results depend on the size of the delays and arc given in terms of linear matrix inequalities , so they arc less conservative than those of delay - independent. Moreover, matching condition is not a necessary condition. Finally, an example is presented to illustrative the effectiveness of the proposed method.
