Icbgm 2001 International Conference on Bond Graph Modeling and Simulation Quantized Bond Graphs: an Approach for Discrete Event Simulation of Physical Systems

This paper introduces a new class of Bond Graph models, called Quantized Bond Graphs (QBG), which can be “exactly” simulated by a Discrete Event System Specification or DEVS structure (Zeigler; 1976, 2000). Standard Bond Graph representing Physical Systems can be approximated by QBG for the purpose of simulation. It is shown that derivative causalities dissapear from this kind of models, turning into causal commutations as in Switched Bond Graphs. Stability properties of the resulting simulation models are also studied. Finally, interesting results obtained from the simulation of a technical system under this approach are shown.
