摘　　要：固定翼无人机着陆性能是限制其发展的重要因素,提升其着陆性能有重要的现实意义。聚焦于着陆中的浅下滑段,对固定油门的传统着陆控制方法进行分析并指出其存在的缺陷。通过姿态、速度和下沉率关系引出过程速度控制和末端速度控制的必要性,提出油门速度闭环控制方案。该方案解决了触地姿态安全问题,大大提高了着陆的精度。Since the landing performance of fixed wing UAV is an important factor limiting the development of UAV,it is of great practical significance to improve its landing performance.This paper focuses on the shallow glide section of landing,analyzes the traditional landing control method with fixed throttle,and indictes its shortcomings.The necessity of process speed control and terminal speed control is derived from the relationship between attitude,speed and sink rate,and a closed loop control scheme of throttle speed is proposed.The scheme solves the problem of touchdown attitude safety and greatly improves the landing accuracy.
