A Bond-graph Representation of a Two-gimbal Gyroscope

Keywords

Abstract

The purpose of this paper is to show, by example of a two-gimbal gyroscope, a method for developing a bondgraph representation of a system from the Lagrangian.

Often the Lagrangian of a system is readily available from texts or other sources. Although the system equations can be derived directly from the Lagrangian, there is still benefit in viewing the system in bond-graph representation. Viewing the power flow through the system gives insight into the inter-relationships of the state variables.

This paper will give an example where the possibility of reducing the order of the system is obvious when viewing the system in bond-graph representation yet is not readily apparent when looking at the Lagrangian or the equations derived from the Lagrangian.
