化工生产过程的混合佩特里网建模方法

针对连续化工生产过程中混杂的离散事件,提出了基于混合佩特里网的建模方法。且由于连续对象的数学模型越来越复杂化,要求越来越高,文中在佩特里网中引入人工神经元网络,以汽提塔液位控制为例,详细分析了连续过程和离散过程的混杂特性。

Modeling based on hybrid Petri net for chemical processes

Regard to the discrete events during the continuous chemical process, a new method of using hybrid Petri net was proposed in this paper. As the mathematical model of the continuous process became more complicated and the objective required more accuracy, the paper introduced hybrid Petri net combining into ANN, and then gave an actual example for detailed analyzing miscellany performances of continuous and discrete events.
