A bond graph pseudo-junction structure for non-linear non-conservative systems

Abstract

Bond graph (BG) models are widely used to display various fields of a physical system and their interconnection. In this paper, a BG pseudo-junction structure for non-linear and non-conservative systems is proposed. This BG pseudo-junction structure has an inner structure that satisfies energy conservation properties and a multiport-coupled dissipative field that determines the physical realisability of the system. Properties of the dissipative field like passivity are highlighted by the proposed BG pseudo-junction structure. The results are illustrated through examples.
