摘要
研究了混合信息下的分散监控综合问题.首先提出δ_可观察(hδ_可观察)可控闭语言是(状态部分可观察下)状态反馈综合解存在的充要条件,并由此得到n_联合可观察、可控闭的系统约束是保证混合分散监控器存在的充要条件,进而得到纯分散监控器(控制器)存在的充要条件为n_可观察(n_hδ_可观察)可控闭语言被满足.最后,又通过研究系统约束与混合约束的关系,提出混合分散监控器存在的充分条件是可观察、可控闭语言与可观察可控谓词被满足.
The synthesis of mixed decentralized supervisory control is investigated.Firstly,a closed,controllable and δ_observable (hδ_observable) language is proposed as the necessary and sufficient condition for the existence of a solution to the synthesis of state feedback (with partial state_observation).And a necessary and sufficient condition that ensures the existence of mixed decentralized supervisor is given by a global constraint which is closed,controllable and n_coobservable.Moreover,a necessary and sufficient condition for the existence of pure decentralized supervisor(decentralized controller) is shown by a closed,controllable and δ_observable (n_hδ_observable) language.Finally, by presenting a relation between global constraints and mixed ones,a sufficient condition obtained for the existence of mixed decentralized supervisor is that the language which is close, observable and controllable and the predicate which is observable and controllable are both satisfied.
