摘　　要：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.
