Hamiltonian Bond Graph formalism for generating energetic redundant relations

In the present paper, an alternative causal graph-based fault detection scheme is designed. The Hamiltonian Bond Graph (HBG), as a graphical model combining the Bond Graph (BG) and the Port Hamiltonian (PH) formalisms for characterizing power interactions between submodels, is involved herein in modeling and fault detection of multi-energies systems taking into account of energy concepts. Owing to energetic and structural aspects, the generic model is competent to deduct immediately the energetic redundancy relations by covering the causal energetic paths. The performances of the suggested scheme is proved by the simulation results on the DC motor.
