Bond graph, Singular perturbations, Quasi-steady state models
A bond graph model of a three-time scale system is presented. The original system is decomposed into slow, fast 1 and fast 2 (faster than fast 1) sub-systems. Reduced models that determine the quasi-steady state model are obtained. By removing the fast dynamics assigning a derivative causality and
maintaining an integral causality assignment, reduced models are obtained. This reduction is done in two parts: first removing the fast 2 dynamics and then fast 1 dynamics. Finally, the proposed methodology is applied to an example.
