| 英文摘要 |
| This paper presents a new control scheme for the problem of a space manipulator after capturing an unknown
target. Since the inertia parameters of the combined spacecraft have been identified online depending on momentum-based
estimation method and recursive least squares algorithm, a direct parametric approach via proportional plus derivative
feedback is proposed for the combined attitude control system, which gives a complete parametrization of the pair of
feedback gains. Considering the thruster’s configuration and the measurement error of the configuration matrix, robust
control allocations with perturbation both in regular polyhedral and polytopic form are developed. Finally, numerical
simulations demonstrate the effectiveness of the proposed approach. |
