Multi-model hybrid system and the stability analysis

Multi-model nyorid system was introduced, This class hybria system is a collection ot subsystems defined on different sub-space, which are related by a switching logic. When a discrete event takes place at some time, the discrete state of the hybrid system would switch from one state another. And at that moment, the continuous state of the hybrid system would have has a discontinuous change. This class system can describe the dynamic behaviors of very complete system more precisely. Further more, the stability of this class system was analyzed and a sufficient condition for the stability of this system was given.
