Spacecraft Attitude Control Using Magnetic and Mechanical Actuation

© Copyright 2015 by the American Institute of Aeronautics and Astronautics, Inc. The aim of this paper is the analysis of simultaneous attitude control and momentum-wheel management of a spacecraft by means of magnetic actuators only. A proof of almost global asymptotic stability is derived for control laws that drive a rigid satellite toward attitude stabilization in the orbit frame when the momentum wheel is aligned with one of the principal axes of inertia. Performance of the proposed control laws is demonstrated by numerical simulations under actuator saturation. Robustnesstoexternal disturbances and model uncertaintiesisalso evaluated.
