摘　　要：混合系统是一类既包含连续动态行为又包含离散动态行为的系统,这类系统在实际应用中显得越来越重要,对这类系统需要探索新的模型和研究方法。该文在概述混合系统概念、特点以及发展近况的基础上,主要综述了近年来混合系统研究中的一些重要问题,指出现有各种方法的优缺点,并指出了今后的研究方向。该文首先介绍了混合系统研究中多种常见的建模方法,如混合自动机、Petri网和时段演算,然后重点讨论了混合系统一些重要性质,主要集中在对系统稳定性、可达性、可观性的分析方法上,以及混合系统的多种设计方法,并且对这些方法进行了初步评价,最后介绍了混合系统研究中一些常用的仿真工具。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, reaehability 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.
