摘要

为了高精度地匹配跨月注入，提出了一种相位环的近优轨道控制方法。根据高斯变分方程进行了灵敏度分析，并制定了近优轨道控制策略。提出了一种顺序拍摄方法，以减少每个拍摄问题的尺寸并提高收敛性。为满足地面设施的可达性要求，提出了机动位置调整策略。通过与差分修正法的比较，验证了近优方法节省ΔV 的优势。利用高保真动态蒙特卡洛模拟验证了实用方法的稳健性。这项研究的结果可应用于月球探测器跨月注入前的相位环中期校正。

Near-optimal maneuver design for high-accuracy trans-lunar injection with highly elliptical phasing loops

To match the trans-lunar injection with high accuracy, a near-optimal orbit control method for phasing loops is proposed. Sensitivity analysis was performed based on Gauss’s variational equations, and a near-optimal orbit control strategy was developed. A sequential shooting method was proposed to reduce the dimensions of each shooting problem and improve convergence. To satisfy the accessibility requirements of ground facilities, a maneuvering location adjustment strategy is proposed. The advantage of the delta-V saving of the near-optimal method was verified by comparing with the differential correction method. The robustness of the practical method was verified using Monte Carlo simulations with high-fidelity dynamics. The results of this study can be applied to midcourse correction of phasing loops before the trans-lunar injection of a lunar probe.
