Abstract:This paper studies the non-linear control of a spinning electrodynamic tether system during its spin-up process. The main problem of the spin-up process is that the tether shape may become irregular due to distributed electrodynamic force, which can lead to risks such as entanglement of the deformed tether with end bodies (base spacecraft and sub-satellite). To deal with this problem, a nonlinear control strategy is proposed in this paper for reducing tether deformation and for stabilizing attitude motions of … Show more
