Abstract

This paper presents a component oriented modeling environment for building hybrid dynamic models of physical system. The modeling environment is created using the Generic Modeling Environment (GME), a metaprogrammable visual modeling application developed at the Institute for Software Integrated Systems (ISIS). The core of the modeling language itself is a hybrid extension of the bond graph modeling language. The advantages of an object-oriented approach to physical system modeling combined with the advanced features of GME for managing model complexity are illustrated by building a library of hydraulic system components. A simulation model can be automatically generated from the physical system model using a model translator. As an example application we use the component library to build the model of a coupled multi-tank system with controlled and autonomous hybrid behaviors, and illustrate this with a simulation example.
