Analysis and simulation of multiport systems—The bond graph approach to physical system dynamics

Abstract

The Bond Graph modelling technique developed by Paynter and extended by Karnopp and Rosenberg is introduced briefly and is illustrated by its application to the modelling of a prototype electro-mechanical tape-drive system. A set of state-space equations representing the system is readily determined from the Bond Graph model, and frequency and time response measurements made on the model correlate well with those of the physical system. The effect of parameter variations and different models for the component parts were readily examined using this approach.
