Automated model builder of hybrid bond graph: Application to a two level inverter

Abstract

CCAMY systems in partnership with Lille University currently develops Emulatio: a simulation and diagnosis platform for multi-physic systems, using Hybrid Bond Graph. This platform is devoted to automatically build model of industrial Computer-Aided Design schematics, then generate Block-Diagrams for simulation and export Global Analytical Redundancy Relations for model-diagnosis. For this task, a description language is needed. This paper proposes a new modelling language for Hybrid Dynamic Systems named Hybrid Bond Graph Modelling Language. Hybrid Bond Graph Modelling Language is an extension of BGML, designed to help hybrid Bond graph developers with some new features such as specific tags for hybrid causality algorithm assignment procedure, multi-mode equations and new hybrid elements as controlled junctions. The developped language is illustrated by an application to a two level inverter circuit. Finally perspectives are discussed.
