Abstract

This paper mainly focuses on a control scheme which is proposed for realizing the artificial gravity mission using a spinning tether system. First, the mathematical model of space tether system is established by Lagrangrian modeling method. Then, a desired trajectory is designed by a passive deploy method and spin method to make the whole tether system meet the mission requirements. Finally, a closed-loop non-singular fast terminal sliding mode controller is designed considering the presence of external disturbances and initial error to ensure the closed-loop tracking. The effectiveness of the control strategy is verified by numerical simulation.
