In this paper, an attitude-orbit integrated control law based on the fully-actuated system approach is proposed for spacecraft formation flying system. A 6DOF attitude-orbit integrated kinematic and dynamic model based on SE(3) description is established, and the fully-actuated system model is derived. Considering the effects of disturbances and unknown items of model, an adaptive neural network is designed to compensate the effects. Further, a fully-actuated-system-approach-based controller is developed for spacecraft formation flying tasks. The convergency of formation tracking error is proved via the Lyapunov stability theory. Finally, numerical results indicate the effectiveness of the control law proposed in this paper.
