Large Angle Super Agile Attitude Maneuver Control of Small Satellite using Reaction Wheels

Super agile imaging mode can effectively solve the contradiction between short transit time and various imaging tasks, and can significantly improve the satellite observation efficiency. The premise of its on-orbit implementation is to greatly improve the attitude control ability of satellite platform. In order to satisfy the requirement of super agile attitude maneuver control for multi-target imaging task, an "attitude planning + moving horizon tracking" control scheme for rigid satellite using reaction wheels is designed. Based on the analysis of the performance requirement of attitude control for multi-target imaging task, two methods of attitude determination in the stages of attitude maneuver and stable control are proposed. The control model of the rigid satellite is established, and the super agile attitude maneuver trajectory is designed based on the three-stage planning method, then the moving horizon optimization tracking control method is proposed to realize the super agile attitude maneuver control. The effectiveness of the proposed control scheme is demonstrated by numerical simulation.
