摘　　要：利用混合Petri网对一类典型的混合系统——模式切换系统进行建模和分析;提出模式切换系统动态平稳性的概念;给出了二维模式切换系统的平稳条件以及求解平稳点的算法,并用实例进行了说明。A class of hybrid systems named switching mode systems is considered in this paper. Such systemsconsist of many different evolution modes. Within each mode the dynamics is define by a constant vector. The active mode is supervised and selected by the discrete controller. Firstly, a model of hybrid dynamic sys-tems based on hybrid Petri nets is presented. Then its dynamic behavior, especially for the two -dimensional systems, is studied. Finally, some attractive examples are given to explain the analysis method in this paper.
