Simulation Analysis on Proximity Control for a Space NonCooperative Target

Abstract: The proximity process in a close distance is very important for onorbit servicing. In this paper, the kinematics and control for this process are studied. The relative position model and relative attitude model of the servicing spacecraft towards target spacecraft are established. The proximity guidance law in straight line is used with respect to the coordinate of the target spacecraft. The relative motion states are tracked and controlled under a usual PD control law. Finally, the Simulink dynamics model is established, and the corresponding simulation and analysis are carried out. The simulation results indicate the reliability of six dimensional relative motion models and the validity of the control method.

Key words: noncooperative target, relative position, relative attitude
