The invention discloses an intelligent lunar soft landing orbit controller. The orbit controller comprises a simulation module, an optimizing module and an execution module, wherein in the simulation module, the lunar soft landing orbit is divided into a plurality of segments, a thrust direction angle changing curve of the orbit is fitted by aid of thrust direction angles of nodes at segmentation and corresponding moments, and then the whole soft landing orbit is obtained through simulation of a soft landing dynamic model. The optimal thrust direction angles of the nodes and the optimal soft landing terminal moment are obtained through optimizing of the optimizing module. The optimizing module adopts an improved intelligent algorithm, the improved intelligent optimizing method controls the size of subgroups, disturbance factors are added, searching variety is improved, and the optimizing module has very high searching capacity and can search a lunar soft landing orbit requiring the least fuel consumption through optimizing. An optimal soft landing command signal is transmitted to the execution module, and the optimal lunar soft landing control requiring the least fuel consumption is realized finally.
