Aiming at the problem of UAV landing flap configuration, the precise landing control technology of UAV is analyzed. The shortcomings of the traditional throttle speed control in the shallow glide phase on the precision landing performance were analyzed. Nonlinear simulation test of the shallow glide phase was designed, and the dynamic function relationship between the airspeed and the sink rate under different loads was established. Based on the speed control, the terminal guidance control algorithm in the near section was proposed. The typical robustness simulation test was carried out by the semi-physical platform with high confidence. The results show that this technology can improve the touchdown accuracy from 100 m to less than 50 m, and also improve the performance of the landing perimeter.
