Abstract
Analysis of systems are often done from a Linear Time Invariant (LTI) approach. This approach does not represent the continuous and discontinuous behaviour of a hybrid or switched system on a single model. As a result, hybrid systems are often represented as a sequence of LTI equations depending on the configuration of switches or modes of operation. Bond graph are an established modelling method, in which there are several methods to represent the commuting elements. This paper aims to set a standard notation for hybrid bond graph in order to derive a unique representation that encompasses all modes of operations and from which multi-modes analysis can be undertaken. Switching elements are modelled using controlled junctions and this leads to the use of dynamic causality for mathematical model generation and model analysis. From the junction structure of the dynamic causal bond graph representing the hybrid system, a mixed-Boolean implicit unique model is derived for the system enabling the determination of valid operational modes.
