In fact, we go even a possibility of checking the property structural of monitorability of all the components bond graph, directly starting from the model bond graph multi-energies, without the need for generating analytical relations of redundancies or any other numerical calculation.enBond graphmulti-energy Bond graphcausalitymulti-causalitymultigraphemonitoring abilityoperation of couplingArticle
