Internal Mass Motion for Spacecraft Dynamics and Control

Authors: Christopher D. Hall; VIRGINIA POLYTECHNIC INST BLACKSBURG
Abstract:
We present a detailed description of the application of a noncanonical Hamiltonian formulation to the modeling, analysis, and simulation of the dynamics of gyrostat spacecraft with internal mass motion. The methods have been applied to the practical implementation of control of a three-dimensional air bearing spacecraft simulator. We also present the analysis of electrodynamic tether systems, including optimal control of a simplified model.

Limitations: APPROVED FOR PUBLIC RELEASE
