Abstract：An coupled control strategy was developed for proximity operations of spacecraft formation flying which tabes into account the unknown but bounded disturbance, parametric uncertainties and actuator saturation. An auxiliary system is used to compensate for the effects of input constraints. The auxiliary system states are applied to the control design and stability analysis. The system was an adaptive updating technique that does not need to know the system parameters and the unknown bound of the external disturbance in advance Lyapunov theory shows that this controller guarantees uniform ultimate boundedness of all the signals in the closed-loop system and that the tracking errors will converge to a small neighborhood of the origin. Finally, a six degree of freedom simulation demonstrates the effectiveness of this control law compared to an approach that does not consider actuator saturation.
