The invention discloses a small celestial body detector landing control method for online estimating non-model interference, relates to the technical field of small celestial body landing control, and solves the problems of incapability of obtaining an upper bound of the non-model interference and incapability of realizing precise and safe landing control in traditional small celestial body detector landing control. The method comprises the following steps: firstly, a trajectory capable of guaranteeing safe landing in time tau is designed, and anticipant descending positions, descending speeds and descending accelerations in three directions of X axis, Y axis and Z axis are determined; then, the non-model interference is estimated online in real time by designing an estimation function based on present position, speed and acceleration operation state information of a detector in the process of realizing the small celestial body detector landing; and finally, a control law is obtained based on the stability theorem of Lyapunov second method to obtain control accelerations of the detector in three directions, and the detector is controlled to track a nominal trajectory to guarantee precise and safe landing of the small celestial body detector.
