The invention discloses an orbital transfer control method and device for a moon-around spacecraft. The orbital transfer control method and device for the moon-around spacecraft achieve orbital transfer of the spacecraft into a full-parameter target orbit. The method comprises the following steps: designing a three-pulse control strategy of far-moon maneuvering, phase modulation control and period control; based on the orbit plane, the camber line and the perilunar height, the control moment and the omnidirectional control pulse of orbit transfer from the initial orbit to the first middle orbit are determined; based on the orbit phase, determining a first tangential pulse for orbital transfer from the first intermediate orbit to the second intermediate orbit; and determining a second tangential pulse for orbital transfer from the second intermediate orbit to the target orbit based on the orbit period. The first tangential pulse and the second tangential pulse are used as variables, the far-moon maneuvering position vector deviation value is used as a fitness value, and the initial value of each pulse is solved by adopting a genetic optimization algorithm. The problem of orbit control solving caused by orbit evolution nonlinear enhancement and complex omnidirectional pulse control parameters under the influence of perturbation is solved.
