Abstract

Abstract: The deorbiting electrodynamic tether system is a typical active space debris removal technology. In this paper, the feedback control of the tension and current is investigated for the deployment of an electro-dynamic tether system without the consumption of chemical propellants. First, considering the effect of the tether mass, a dynamic model for the two-body electro-dynamic tether system in low earth orbit is developed based on the geomagnetic field modeled using a tilted dipole approximation. Then, a control scheme forthe physical bounds of the tether tension and electric current is proposed by using the anti-windup compensator and the backstepping method. Furthermore, with the introduction of dynamically scaled generalized inversion, the control law is improved to achieve deployment stabilization of the underactuated electro-dynamic tether system. Within the Lyapunov framework, the stablilization of the system state is analyzed. Finally, simulation study is carried out on the platform of MATLAB/SIMULINK to evaluate the performance of the control strategy. The results indicate that the length of the tether converges to the desired value by controlling the tension and current while the feedback control inputs remain within the prescribed bounds all the time.
