摘　　要：This technical note presents a practical approach to low-energy Earth–Moon transfer autonomous guidance considering high-fidelity orbital dynamics.Initially,autonomous guidance,delineated as a trajectory-tracking problem,is addressed within the framework of a predesigned reference trajectory solution,accompanied by empirical trajectory correction maneuver allocation.A series of two-point boundary value problems is subsequently formulated to incorporate guidance velocity increments.An algorithm employing quasilinearization,discretization,and recursion is proposed to address these boundary value problems,which results in enhanced convergence performance compared with traditional differential-correction-based guidance methods.Finally,a Monte Carlo analysis demonstrates the efficacy of the proposed autonomous guidance approach,indicating its potential for onboard applications.
