摘　　要：通过对混杂系统典型实例即三水箱系统特性的分析,从系统安全的角度讨论了用于控制该系统离散状态切换序列的基于混杂自动机描述的贪婪型与周期型控制策略。依据此控制策略,利用VC++与Matlab的混合编程技术开发了该混杂系统的虚拟对象实验室平台。通过对三水箱系统及仿真环境参数的设置,此平台不仅可以形象地演示虚拟对象在不同初始条件下的混杂特性,而且可以实现预定的控制策略并进行仿真研究,从而为具有此类混杂特性的混杂系统的深入研究,提供了一个虚拟的实验环境。Greedy and periodic control strategies based on the description of hybrid automata are discussed to control the switch sequence of discrete states from the perspective of system safety by analyzing characteristics of the typical hybrid system, three-tank flow system, According to these control strategies, the lab platform of virtual objects for this hybrid system is developed using the mixed programming in VC ＋ ＋ and Matlab. Through setting the parameters of three-tank flow system and simulation environment, this platform can display live hybrid characteristics of virtual objects under different initial conditions, implement predesigned control .strategies, and carry out simulation study. Therefore, this platform provides a virtual experimental environment for the further study of hybrid systems involving the same hybrid characteristics.
