Special kinds of decentralized control problems
Jinzhi Wang · Control theory & applications · 2004
A special kind of decentralized control problems was studied, and the decentralized stabilizable conditions were established. In some cases, it is impossible to stabilize all subsystems and the whole system simultaneously by using decentralized controllers. In order to stabilize the whole system, some subsystems should be assigned to be unstable. The results showed that the stability of interconnected systems is dependent on the harmony of subsystems sometimes, rather than on the stability degree of subsystems. Finally the example of decentralized control was presented.
