INFINITE FIXED MODES IN SINGULAR DECENTRAL CONTROL SYSTEMS
广义分散控制系统的无穷远固定模

In this paper,we study the fixed modes of the singular decentral control systems.First,for the singular decentral control systems,we present the concepts of finite fixed modes,in-finite fixed modes and impulsive fixed modes.Then the necessary and sufficient condition forthe nonexistence of impulsive fixed modes is presented and proved.Furthermore,this condi-tion is calculable by elementary transformation.
