The tether-based artificial gravity construction and control for manned long-term space mission

A control scheme of artificial gravity based on the spinning tether system is proposed for manned long-term space mission in this paper. Firstly, the mathematical model of space tether system is established by Lagrangrian modeling method. Secondly, a passive deployment method is designed to realize the rapid deployment control of hundreds of meters short tether. Finally, to deal with the overload stability, a global fast terminal sliding mode controller is designed under the spinning of in-plane motion. The proposed artificial gravity scheme is validated by numerical analysis.
