摘要

The present article addresses the relative robust pose control issue of a spacecraft with respect to a high-spinning debris during eddy-brake detumbling. To do so, the relative pose dynamics is firstly given and then transformed into a two-order fully-actuated system (FAS) based on the recognition of the dynamic characteristics, where the system parameter perturbation is taken into account and analyzed as well. After that, a robust nonlinear control scheme arising from the fully-actuated system approach is proposed, comprising a feedforward item for compensation and a feedback item for. The gains of the feedback controller are then derived via parametric eigenstructure assignment for various control aims. In the end, the given control scheme is verified to be effective by numerical simulations.
