摘要
对于连续系统提出了一种受控连续 Petri网模型 .该模型充分考虑了系统状态的时变性质 ,在普通连续 Petri网的基础上 ,对连续变迁的激发速度及触发规则进行了重新定义 ,从而能直观地、充分地描述受控连续系统的演变 ,从而为混杂系统统一的 Petri网模型框架的建立提供了理论基础 .利用模型详细讨论了连续系统的时间最优控制问题的连续 Petri网描述 .
A controlled continuous Petri nets model for continuous systems was presented. Based on the ordinary Petri nets, this model considers the time\|varying properties of the system states and redefines the fire velocities and the fire rules of the continuous transitions, so it can describe the evolution of the controlled continuous systems sufficiently and intuitively. As an extension of continuous Petri nets, this model offers theoretical base for the foundation of the unified framework of hybrid systems. As an example, the continuous Petri nets depict of time\|optimal Control problem of the continuous systems was discussed in detail by using the model.
