Longitudinal Control Strategy for Precision Landing of UAV
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.
