| Abstract: | In bond graph models, the atomic submodels are described by sets of equations. Because of the physical justification of the bond graph formalism, it provides extensive possibilities for verification of the model at the graphical level. The equation formulation on the other hand is founded in the mathematical domain, so the need for a check against physical criteria is both more needed and more difficult. Causality assignment is the meeting point of the graphical level and the equation level. In bond graph modeling, causality assignment is a vital step in analysis and simulation. The assignment process in the graph is based on the causality restrictions of the atomic submodels. In this article, an automatic procedure for the derivation of causality restrictions of atomic submodels is presented. This process not only generates the correct set of causality restrictions, but also provides a detailed verification of the correctness of the submodel |
