Automatic Construction of Processes from a Bond Graph Representation

The ahn of this paper is to propose an automatic method to construct a process model from a bond graph representation. The system is described in a multimodeling approach. In this approach several models represent the functional knowledge: the func- tional role model and the process model. Functional roles m-e in correspondance with bond graph elements and it is shown that the causality and the orientation o( tile energy flow have to be taken into account in or- der to build the processes cofunctions. An algorithm is given which constructs these cofunctions from the bond graph representation. This method is applied to con- struct the processes of a lmclear power plant coolant loop and is illustrated on a simplified pm't of this sys- tem. The methods based on the multimodeling ap- proach for interpreting or for diagnosing systems can usefully rely upon this automatic construction of pro- cesses.
