Abstract: For attitude large-angle maneuver control of spacecraft, according to the standard cascading characteristic of the spacecraft attitude tracking system, a finite-time controller is designed by using the backstepping method and the adaptive control under the condition of external disturbances existing. The proposed controller can strictly guarantee that the attitude large-angle maneuver system is finite-time stable globally. The Lyapunov theory and simulation results show that the system can quickly maneuver to the equilibrium point and hold steady. The full-physical simulation experiments also demonstrate the effectiveness and superiority of the proposed control scheme.
