摘要: 研究镇定多通道系统的一种新策略--动态递阶控制.对线性时不变确定型通道强关 联系统,得到了在给定信息结构下采用动态递阶控制可任置极点(镇定)的一个充分必要条 件,解决了分散循环系统采用动态递阶控制时的最小信息结构问题,并讨论了动态协同控铋 器的最小阶数,最后给出了一个数值例子.Abstract: This paper studies a new scheme for stabilizing linear multichannel systems named dynamic hierarchical control. For linear time-invariant multi-channel systems which are channel-strongly-connected, a necessary and sufficient condition is obtained, under this condition the systems can be stabilized by dynamic hierarchical feedback with a given information structure, and for those which are decentralized cyclic information structure, the minimal information structure problem of dynamic hierarchical control is solved, and the minimal order of the dynamic coordinators is estimated. A numerical example is given to illustrate the results.
