Abstract
The theory required to model a system using a bond graph is presented and a computer
aided bond graph modelling program is implemented. The program allows the bond graph to be
entered and modified and automatically assigns the causality. Using the bond graph and
the equations entered by the user, the program creates an ACSL input file and performs an
ACSL simulatlon. The program is able to deal with systems containing algebraic loops and
derivative causality. The LISP source code is included in the dIssertation. Numerous bond
graph models of systems in different domains are presented and examples of how the program
is used to model, simulate and obtain the linear state-space equations of a number of systems
are shown, The bond graph is a powerful multidomain model representation, particularly
when incorporated in a computer aided modetling program.
