Abstract :
This technical note proposes a novel sensor placement approach based on the bond graph (BG) for isolability. It is investigated in the linear differential-algebraic equations model regarding a BG. Causal paths are employed to capture the cause-effect relationships of model equations. The case study shows that this novel approach is independent of causality assignment on BGs and performs well.
