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). 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 foe managing model complexity are illustrated by building a library of thermofluid 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 thermofluid system with autonomous hybrid behavior, and illustrate with a simulation example.
