Colored Petri nets for modeling of networked control systems
Khamsa Farah, Karim Chabir, Mohamed Naceur Abdelkrim · 2019
Networked control system (NCS) is a set of entities communicating and exchanging data via a network, which makes its analysis and synthesis complex. Colored Petri nets (CPN) provide a very compact way and a well-adapted and progressive framework for modeling and analysis complex systems in which competition, synchronization, resource sharing and parallelism are present. Our work concerns facilating the practical use of CPN for designing of NCS. For that goal, we will work with cpntools simulator to present a graphical model with hierarchical colored petri nets (HCPN) for the Ethernet network in the first step, starting with the global model, then going through its internal modules, secondly, we will propose a model for different entities that constitute our control system. Finally, we will highlight the operation of this mode and the good flow of data between the various components.
