Abstract

Bond graphs are a powerful formalism for modeling the continuous dynamics of physical systems. To model fast continuous changes as discontinuities, hybrid bond graphs introduce an ideal switching element, the controlledjunction, that may inhibit power transfer by enforcing its common variable to be zero. When bond graph storage components become dependent upon one another because of a discrete state change, their stored value may change discontinuously. Consistent values are computed by conserving the physical state variable (e.g., momentum, mass). One discrete state change may cause a number of further discrete state changes without affecting the state vector. When no further changes occur, the state vector is updated and this again may cause a new sequence of discrete state changes. These consecutive discrete state changes can be classified based on parameter abstraction and time scaleabstraction. HYBRSIM implements the hybrid bond graph modeling paradigm as a Java based modeling and simulation environment.
