Abstract

The fuel carried by deep space exploration spacecraft is crucial for the completion of their exploration missions, and the fuel for attitude control engines is even more precious. In order to reduce the control requirements for attitude control systems, this paper proposes a shape-based trajectory optimization algorithm that considers attitude constraints for low-thrust spacecraft. This method obtains a more accurate transfer trajectory by considering the change rate and change range constraints of the propulsion acceleration direction of spacecraft. By comparing the simulation results without considering spacecraft attitude constraints, it is confirmed that the proposed algorithm considering attitude constraints is very important for the initial design of transfer trajectories. This is of great significance for high-precision initial trajectory optimization of deep space exploration missions.

摘要

深空探测航天器所携带的燃料对于其探测任务的完成至关重要，而姿态控制发动机的燃料则更为珍贵。为了降低姿态控制系统的控制要求，本文提出了一种基于形状的轨迹优化算法，该算法考虑了低推力航天器的姿态约束。该方法通过考虑航天器推进加速度方向的变化率和变化范围约束，获得了更精确的转移轨迹。通过与不考虑航天器姿态约束的仿真结果进行比较，证实了所提出的考虑姿态约束的算法对于转移轨迹的初始设计非常重要。这对于深空探测任务的高精度初始轨迹优化具有重要意义。
