An spacecraft attitude maneuver method based on ADRC

Spacecraft attitude control problem of a class of MIMO control systems, and there is a strong coupling between channels. The ADRC method shows showed some deficiencies. This study proposes an integrated procedure to design the state-feedback decoupling controller to dynamically reduce the coupling effect, and then the non-linear SISO ADRC is designed to ensure the stability of the closed-loop system for each decoupling subject. Finally, the simulation results of a bank-to-turn vehicle model control show that the designed controller has good decoupling performance, with good robustness and adaptability.
