A Study of 'I~ransitions in Dynamic Behavior of Physical Systems 96 QR-98

This paper develops a classification of transition be-haviors for hybrid dynamic systems. Physical sys-tem behaviors often comprise of multiple temporal and spatial scales. A hybrid system model abstracts the operational domain of a continuous system into patches of similar behaviors. Behaviors in each patch are described by simpler models. When state variables cross threshold values, the system makes discrete tran-sitions from one patch to another. We assign physi-cal semantics to the transition behaviors in order to develop a compositional modeling framework and self-consistent simulators for hybrid systems
