In this paper, the spacecraft relative motion control problem with actuator saturation is studied for rendezvous and proximity missions. The decoupled characteristic model of initial system is derived according to spacecraft six-degree-of-freedom (6-DOF) dynamics. Correspondingly, by virtue of the low gain feedback technique, a characteristic model-based adaptive control strategy is developed, which can realize the attitude synchronization and position tracking in the presence of parameter uncertainties and bounded disturbances. Compared with the previous adaptive control design of spacecraft motion, the proposed control strategy possesses a simple structure, and can handle the actuator saturation and improve the robustness of the closed-loop system simultaneously. Numerical simulation indicates the validity of the control method.
