递进式路径转移姿态机动快速规划方法

Large angle attitude maneuver is a common task in current space missions. However, the complex space environment and spacecraft attitude constraints limit the feasible space of attitude maneuver and the efficiency of attitude planning. To solve this problem, this paper studies the rapid planning of large angle attitude maneuver based on multiple constraints, and proposes a rapid planning method based on path transfer strategy. The method is composed of three parts: reference path planning, relaxation path planning, and path transfer planning. The problems of initial reference path generation, attitude bounded constraint satisfaction and attitude pointing constraint satisfaction in attitude planning are dealt with step by step. In path transfer planning, the attitude pointing constraint evaluation function is established based on the pointing angle and the corresponding transfer action set is designed, which can quickly obtain the safe maneuver path satisfying various constraint conditions. Simulation of large angle attitude maneuver shows that the method proposed is fast in terms of maneuver time and efficient in terms of planning speed.
