Application of Constraint Dynamics for Spacecraft Maneuver

Abstract

A new approach for spacecraft maneuver based upon constraint dynamics and tracking control laws is presented in this paper. For high precision pointing requirement on spacecraft maneuver, a desired trajectory is prescribed upon which a constraint dynamic system is constructed. A reference model system governed by constraint force is used to build the associated control laws for actual system. Simulation results for single axis slew maneuvers show that this approach can be used for a spacecraft mission with high pointing accuracy requirement.
