摘要
Petri网是一种图形的和数学的建模工具,适合于许多系统的建模.为了提高Petri网建模能力引入运行步概念,并在连续Petri网的基础上提出一种新型混合Petri网———步混合Petri网,分析该网特点及其运行规则,并用该网分别对数字型PID控制器和模拟型PID控制器进行建模.
Petri net is a graphical and mathematical modeling tool applicable to many systems. In order to improve the modeling power of Petri nets, we introduced the concept of running step. A new Petri net called as “Step Hybrid Petri Net（SHPN）” was proposed based on continuous Petri nets. The characteristics and operation rules of the SHPN were analysed. A digital PID controller and an analog PID controller were modeled using the SHPN.
