对混杂系统的建模提出了一种新的方法，即：连续变量动态系统用扩展的线性连续Ｐｅｔｒｉ网（ＬＣＰＮ）建模，离散事件动态系统用离散Ｐｅｔｒｉ网建模。该方法不仅简化了原来用一般Ｐｅｔｒｉ网建模的复杂性，又充分地描述了系统内连续变量的动态变化，从而使该模型更接近混杂系统的原型
A new method is proposed for the modeling of a hybrid system, namely, Continuous Linear Variable Petri Nets (LCPN) for continuous variable dynamic systems and Discrete Petri Nets for discrete event dynamic systems. This method not only simplifies the complexity of modeling with general Petri nets but also fully describes the dynamic changes of continuous variables in the system so as to bring the model closer to the prototype of the hybrid system
