Extended Covering Path Method

For comparison with the causality inversion method, this procedure is used to generate again ARRs for the switched network in Fig. 4.1. ARRs are derived from the bond graph in Fig. 4.4.

Note that the C elements in derivative causality, the sensors with non-inverted causality and the switch in conductance causality lead to a causal conflict at junction O4 that has been resolved by adding an auxiliary capacitor C Co. Its capacitance is set to zero in the formulation of ARRs. 

the flow sensor Df / is chosen. Junction O2 is the element whose output variable is measured by the flow sensor. Its constitutive relation reads

As a result, for this example, the extended covering path method gives the same ARRs as the inverted causality method.
