Model predictive tether-deployment control for precise landing of tethered reentry body

Abstract This paper proposes a model predictive control method for tether deployment for the precise landing of a tethered reentry body. A set of state variables for a tethered reentry system, in which the reentry body precisely lands at the target point, is numerically obtained and expressed in the form of an approximation function. The tether state is controlled by taking into consideration its deviation from the function. The effectiveness of the proposed controller for the precise landing of the reentry body is validated through numerical simulations.
