The invention discloses a spacecraft control method for short-distance spacecraft orbit pulse game, and relates to the field of spacecraft orbit game. The method aims at solving the problem that an existing spacecraft control method does not meet the actual working environment requirement, and consequently a spacecraft engine cannot work normally under the spacecraft orbit game countermeasure. The method comprises the following steps: acquiring state information of a spacecraft, establishing an inertial coordinate system and an orbital coordinate system, and acquiring position and speed information of the spacecraft under the inertial coordinate system and the orbital coordinate system; establishing a C-W equation by using the position and speed information, and converting the C-W equation into a Ricaati equation to obtain an optimal closed-loop feedback control rate; thrust borne by the spacecraft is obtained, the thrust borne by the spacecraft is converted to be in an inertial coordinate system, and real-time position information of the spacecraft is obtained through thrust changes in the inertial coordinate system; a pulse thrust differential game of Lambert orbit transfer is calculated according to the real-time position information of the spacecraft, and the speed increment required by the rendezvous process is obtained. The method is used for realizing the spacecraft orbit game.
