摘要
提出了大系统的分散能控子空间和分散不能观测子空间的概念.研究了它们分别与集中控制中的能控子空间和不能观测子空间之间的关系.研究中借用了几何控制理论中的方法.结果表明,分散能控子空间和分散不能观测子空间是集中控制中能控子空间和不能观测子空间在分散控制下的自然推广.利用这两个概念,可以从几何角度研究大系统分散控制的几个问题,比如时变分散控制下的系统镇定问题.
The concepts of decentralized controllable subspace and unobservable subspace are presented.The relations between them and their counterparts in centralized control were explored respectively.An approach similar to the geometric control theory in centralized control was adopted.The result shows that the decentralized controllable subspace and unobservable subspace are the natural generalization of the controllable subspace and unobservable subspace to decentralized control respectively.Based on these concepts,some problem,such as stabilizing of large-scale systems by time-varying decentralized control,can be dealt with easily by a geometric approach.
