Abstract:
To achieve the high precision requirement in the final approach phase of autonomous space rendezvous and docking (RVD) on a relative attitude, first an analysis was made on the coupling of attitude and orbit. Next, the highorder sliding mode (HOSM) controller was used to design the attitude and orbit control system in the final approach phase. After that, a beeline guidance law based on the Hill equation was designed. The attitude control strategy shown here used the HOSM controller. Lastly, with the help of Simulink software, a simulation was carried out in terms of the linear variable structure guidance law and relative attitude control law. The results of simulation show that the designed control system meets the requirements of docking.
