摘要
主要研究一类特殊的分散控制问题,给出其可静态分散镇定的条件,并指出在一些情形下,不可能分散镇定整个系统的同时使各子系统也都稳定,也就是说,整个系统要达到分散镇定的结果,必须把部分子系统配置到不稳定状态.结果表明关联系统的稳定性有时主要依赖于子系统的协调性,不一定依赖于子系统的稳定性强度.
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.
