Modeling, Design and Simulation of Hybrid Systems: Review and Analysis

The hybrid systems caontain both the discrete events and the continuous dynamicevents. These systems are becoming more and more important and call for new modeling and analysis approach.After the conception,characteristic,up-to-date development of hybrid systems are introduced,a summary including some major problem of hybrid system is given.And after making some remarks on the advantages and disadvantages of the existing methods,some new ideas about the future possible methods for hybrid systems are proposed.Firstly,some popular modeling methods for hybrid systems,such as hybrid automata,Petri nets and duration calculi,are introduced.Secondly,the quality analysis of hybrid systems which mainly focuses on stability,reachability and observability,is presented as well.Then some design methods for hybrid systems and their evaluation are also recommended.Finally some primary tools of simulation for hybrid systems are summarized.
