Adaptive Control of Spacecraft with a Captured Non-Cooperative Object

Abstract

This paper studies the control of spacecraft with a non-cooperative captured object. The dynamics parameters of the captured object is unknown. An adaptive position and attitude controller is proposed. It is proven that the combined spacecraft can track the ideal trajectory, if the ideal position, velocity, acceleration and ideal attitude, attitude rate, attitude acceleration are all uniformly bounded. Moreover, the detumbling problem of the combined spacecraft is also addressed in this paper. Finally, some simulation examples are presented to demonstrate the effectiveness of the proposed approaches.
