A New Continuous Petri Net: Step Continuous Petri Nets

The Petri net entitled "step continuous Petri net(SCPN)" is proposed. The characteristics and operation rules of the SCPNs are analysed. At the end of this article, a control system and a digital control system are modeled using the SCPNs, which overcomes the shortcoming that the existing Petri nets could not model and simulate control systems and digital control systems.
