A formal verification method of hybrid system and simulation

Hybrid system is a dynamic system that bas discrete state transfer and continuous state variation. Recently, popular hybrid system model includes threshold-event-driven hybrid systems (TEDHS) and polyhedral invariant hybrid automaton (PIHA). Finite state machine is used to describe the discrete feature of hybrid system and reachable set of stream pipe is used to describe its continuity approximately. These methods of system modeling are given in this paper. Furthermore, a verification tool called CheckMate based on MATLAB is used to realize the modeling, simulation and verification of hybrid system.
