During maneuvering processes, spacecraft are prone to triggering the effects of composite disturbances on the system, posing significant risks to the safety of maneuvering tasks. In order to effectively address the impact of composite disturbances on spacecraft maneuvering while enhancing disturbance adaptability, this paper presents a maneuver control method relying on composite disturbance separation and utilization. Considering the reaction wheel dynamic, a spacecraft attitude model with deep coupled has been formulated, allowing for the separation of composite disturbances and mismatched disturbances. Furthermore, disturbance observers are built to estimate the separated disturbances, and a disturbance discrimination operator is designed to evaluate the beneficial or harmful effects of the matched disturbance on system convergence. By combining disturbance observers and the disturbance discrimination operator, a disturbance utilization controller is constructed to compensate for harmful disturbances and utilize beneficial disturbances. Simulation verified the effectiveness of the designed method.
