BUILDING EFFICIENT SIMULATIONS FROM HYBRID BOND GRAPH MODELS

Embedded systems and their corresponding hybrid models are pervasive in engineering applications, therefore, systematic mathematical analysis using these models has become an important research area. Our approach to hybrid modeling with Hybrid Bond Graphs allows for seamless integration of physical system principles with discrete computational structures, but simulating the hybrid behaviors can be difficult and computationally expensive. In this paper, we develop a methodology that transforms Hybrid Bond Graphs into computational block diagrams and incrementally modifies the block diagram when mode changes occur. This forms the basis for a computationally efficient hybrid simulation algorithm.
