Abstract—With the development of space exploration technology and space commercial activities, the number of spacecraft in space is sharp increasing, space resources and environment is facing enormous challenges. Space Autonomous Rendezvous (SAR) is a multidisciplinary complex systems engineering, and has high demands on the precision, reliability, security, and other state constraints. In this paper, the pose synchronization control characteristics are analyzed. Then, the sliding mode surface function and control law are designed, and the feasibilities are proved. After that, via the simulation, pose synchronization control can be achieved with the sliding mode control law. Finally, the control parameter impact on system is analyzed and the result will help to the control system design.
