2. Hybrid models
The model is the translation of the dynamic behavior of a physical system into an abstract representation. It is a necessary step in any study that cannot be reduced to experimentation. Its quality, in terms of fidelity to reality, but also its legibility and usability, are essential.
2.1 Basics of representation
We have already mentioned the continuous/discrete dichotomy and its methodological consequences. To enable a more homogeneous representation of these two types of systems, within the framework of an SDH approach, we can :
extend continuous approaches to include discrete behaviour (e.g. switching bond-graphs) or extend classic discrete approaches to include continuous behaviour (e.g. hybrid Petri nets);...

Software
(non-exhaustive list)
Statemate: this software for simulating statecharts was developed by D. Harel, the creator of this tool, and his team. It also includes another type of graph, activitycharts, and can be used to create industrial-style man-machine interfaces, with pushbuttons and LEDs.
Stateflow: this is a module of the Matlab/Simulink software; it therefore benefits from...

Working group on hybrid dynamic systems
The French working group on hybrid dynamic systems operates under the aegis of the Société de l'électricité, de l'électronique et des technologies de l'information et la communication (SEE) and the Club des enseignants et chercheurs en électronique, électrotechnique et automatique (club EEA). It is part of the Groupe de recherche en automatique (GdR Automatique)....
