Bond Graph Approach to the Modeling and Simulation of a Two-Axis Pointing and Tracking System

The pointing and tracking system has complex mechanical interconnections, electrical/mechanical interdisciplinary nature, and the necessity to create the model in a three dimensional setting. The paper discusses in detail the bond graph model of the overall system, which is developed from the Lagrangian and implemented using the software 20-sim. The simulation demonstrates that the approach presented in this paper indeed offer the capability to solve serious coupled problems of the three dimensional rigid-body dynamics.
