Energy Flow Modeling of Mechatronic Systems via Object Diagrams.
Martin Otter, HÅKAN ELMQVIST · elib (German Aerospace Center) · 1997
. Object diagrams are generalizations of block diagrams and of bond graphs, and allow modeling of input/output signal flow as well as energy flow. It is shown how object diagrams can be used for the modeling of mechatronic systems, consisting of 3-dimensional mechanical systems, electrical circuits, drive trains, control blocks etc. Emphasis is given to the description of energy flow between different components. Contrary to domain-specific packages, all the details of an object diagram, such as equations of elements, graphical layout of icons or submodels, are defined in a "soft" way, not built into the package, and can be directly accessed by the user, to either use it as a template for user-defined model types or to make modifications that are necessary for the problem at hand. 1. Introduction The modeling of mechatronic systems is difficult because such systems consist of components from different domains, especially they contain mechanical, electrical, hydraulic, control system ...
