分散固定阻塞零点与分散强镇定

研究多通道系统的分散强镇定问题.对集中控制系统的阻塞零点概念提出一种推广的定义.在此基础上,对分散控制系统引入了关于通道及系统的分散固定阻塞零点等概念,揭示出分散系统的阻塞零点与反馈结构的关系.利用这种关系,在比已有结论更弱的假定下,给出了可分散强镇定的充分必要条件及相应控制器求解的一般步骤.

Decentralized Fixed Blocking Zeros and Decentralized Strong Stabilization

This paper is concerned with decentralized strong stabilization problem of linearTime-ivaariant multi-channel systems.First,after generalizing the notion of blocking zeros to systems which are not necessarily controllable and observable,decentralizedfixed blocking zeros with respect to each channel and with respect to the wholesystem are introduced.Then,under a weaker asswumption than previous results,a necessarey and sufficient condition for stabilization to occur with stable decentralizedcontrollers,termed in such zeros,is proved.The constructive proof also providealso provide a procedure for synthesizing such controllers.
