摘要 混合系统是集连续动态系统和离散事件为一体的复杂动态系统,是近年来控制理论研究领域的热门课题。由于混合系统既含连续变量又含离散事件,给处理这类系统带来了复杂性。一般混合系统建立模方法有:混合自动机,混合petri,时段演算及其扩展等模型。在概述混合系统概念与特点的基础上,介绍了混合系统研究中的建模与仿真问题。结合超市冰柜系统用混合自动机建模,并用MATLAB中的SIMULINK和STATEFLOW进行仿真。仿真结果表明效果很好,为系统分析和设计提供了有力的工具。 Hybrid system is a complex system with both continuous dynamic and discrete events. It is a pop field in control theory in recent years. According to the features of the hybrid systems including both continuous variables and discrete events,it is very diffcult to analyse it. The method for modeling hybrid systems includes：hybrid automata,petri nets and duration calculi. Based on the introduction of the conception and characteristic, this paper introduces the problem of modeling and simulating hybrid systems. And hybrid finite automata are used to modle supermarket refrigeratory,and STATEFLOW in MATLAB is used to carry out simulation. The result of simulation shows that using stateflow of MATLAB for simulating hybrid systems has a good effect.
