Abstract
This paper proposes a compound control method for spacecraft multi-body separation which is based on active disturbance rejection control (ADRC), aiming to address the problems of decreased control accuracy and collisions caused by model uncertainty and vacuum plume disturbance. By comprehensively analyzing the positional relationship and attitude between each separator, the compound flight controller reconstructs the desired attitude of each separator based on artificial potential field method and realizes the tracking of the desired attitudes through ADRC. The closed-loop stability of the system is analyzed, and it is proved that the algorithm is stable in the sense of Lyapunov. The simulation results showed that the multi-body separation compound control strategy based ADRC has more advantages in robustness and security. This method is simple to implement, and it has value of reference and application in spacecraft multi-body separation.
