Abstract

The paper demonstrates, by means of an example of a gyroscopically stabilized platform, the method in which bond-graph models can be used in an object-oriented manner to create an overall physical system model. The gyroscopically stabilized platform was chosen as an example because of its complex mechanical interconnections, electrical/mechanical inter-disciplinary nature, and the necessity to create the model in a threedimensional setting.

The paper discusses in detail the bond-graph models of each of the object-oriented system sub-components as well as the model of the overall system. The model is implemented using a new bond graph library implemented in Dymola, which is described in the companion paper: Object-oriented Modeling of Complex Physical Systems Using the Dymola Bond-graph Library, also presented in this conference. The paper demonstrates that the tools/methods presented indeed offer the capability to solve serious engineering problems.
