摘要
New stability conditions for complex switched systems are presented. We propose the concepts of attractive region and semi-attmctive region, which are used as a tool for analyzing the stability of switched systems with unstable subsystems. Based on attractive region the sufficient conditions with less conservative for stability of switched systems have been established, """"there is no limitation for all members of the system set to be stable. Since our results have considered and utilized the decreasing span of oscillating solutions of the switched systems, they are more practical than the other presented ones of stability of switched systems, and need not resort to multiple Lyapunov functions.
