Mode Initialization when Simulating Switched Bond Graphs
1998 (English)In: Proceedings of the 2nd IMACS International Multiconference on Computational Engineering in Systems Applications, 1998Conference paper (Refereed)
When simulating hybrid systems using switched bond graphs, the initialization of new modes is made by using a generalization of the principle of momentum conservation. Here it is shown how to use causality propagation to get an efficient initialization algorithm. By looking at causal paths, set of variables that have to be initialized simultaneously are found. Furthermore, it is shown how impulses due to structural changes in the system can be found with a correct initialization and with a correct treatment of modes with causal conflicts between sources.
