一、引言近年来,大系统的局部分散控制已经得到了很多研究,取得了较好的结果。这些可见专著[9,18,20]及论文[1—8,10—17,19,22]。1974年,DaVison 首先对孤立子系统为可控标准型的线性大系统进行了研究,以后 siliak 等人在这方面做很多很好的工作[6—8,16,19]最近我们也给出了一些结果17。在所有这些文章 I. INTRODUCTION In recent years, the decentralized control of large systems has got a lot of research and achieved good results. These are visible monographs [9,18,20] and papers [1-8,10-17,19,22]. In 1974, DaVison first studied the large-scale linear system whose orphan subsystem is a controllable standard. Later Siliak et al. Did a great job in this respect [6-8,16,19] Recently, we also give a Some results 17. In all these articles
