Abstract: This paper discusses the problem of rendezvous with a maneuver target spacecraft. Considering the maneuvers of the target spacecraft, as well as the external disturbance forces and the coupled states, a modified compress method is proposed and applied to establish the decoupled characteristic model based on the measurements of relative position. Then, a decoupled adaptive control method based on the characteristic model is presented to achieve the rendezvous of the two spacecraft. Finally, the simulation results demonstrate the effectiveness of the proposed method, and indicate that the method is better than the traditional PD control.
