According to the orbit control speed increment estimation method suitable for the rendezvous and docking task of the lunar orbit, the initial speed increment required by orbit transfer is combined with different orbit control engine combination modes, meanwhile, the characteristics of instruction time delay, execution mechanism time delay and the like of different control systems are fully considered, and before orbit control is executed every time, the orbit control speed increment can be estimated to be more accurate. And the orbit control speed increment is accurately estimated. According to the orbit control task speed increment calculation method capable of meeting the high-precision orbit control requirement, the estimation calculation precision of the orbit control speed increment is improved, and it is ensured that a spacecraft can execute high-precision orbit control.
