摘 要：In this paper, a dynamic model for leader-follower spacecraft formation is established, and based on the cascade control theory, the attitude control of the leader spacecraft and the relative position control between the leader and the follower spacecraft are considered. Then, the stability of the whole system is proved according to the stability theory of cascade system. Finally, the actuator saturation of the follower spacecraft is considered, and simulation shows that the whole system is asymptotic stable.
