摘要
混杂系统是集连续动态和离散事件为一体的复杂系统,是近十余年来控制理论研究领域的热门课题,混杂动态系统的研究为解决一类复杂的、非线性的大系统提供了一个很好的理论框架,计算机仿真是分析和研究混杂系统的有效工具。该文在分析混杂系统仿真关键问题的基础上,提出如何应用MATLAB环境中的状态流工具箱,实现基于混杂自动机模型的混杂系统仿真,并就典型混杂系统给出仿真实例。结果表明,应用MATLAB状态流工具箱进行混杂系统仿真,具有很好的可视化,而且混杂系统的离散和连续两部分可以很好的同步协调,结构简单而明了,效果很好。
Hybrid system is a complex system with both continuous dynamic and discrete events. It is the pop field in control theory in recent ten years and provides a good theory framework for resolving sorts of complicated nolinear systems. Computer simulation technology is the effectual tools for analyzing and researching the hybrid systems.The key problem for the simulation of hybrid systems is the synchronization between the two kinds of models. By analyzing the key problems for simulation of hybrid system, we provide a method for simulation of hybrid systems based on the model of finite automata applying in stateflow toolbox in MATLAB. The typical examples are given to illustrate the method. The result of simulation shows that using stateflow of MATLAB for simulating hybrid systems has a good effect and it is very concise. And we can coordinate two parts very good.
