Abstract

This paper presents an algorithm for autonomous landing approach of a unmanned aerial vehicle. The main purpose of the autonomous landing approach in this study is to help a safe landing at night. From any initial position of the aircraft when this function is engaged, a flight path command is generated from the initial position. The shortest combination of an initial circular arc, a straight line segment, and a final circular arc is chosen for the flight path that will lead the aircraft to one end of runway for a landing. The algorithm is initially validated through numerous simulations with various initial conditions of aircraft. Then it is successfully validated through a number of flight tests.

본 논문에서는 무인 항공기의 활주로 자동 접근 알고리즘에 대해 기술하였다. 본 연구에서 자동 접근의 주요 목적은 야간에 항공기의 안전한 착륙을 돕기 위함이다. 자동 접근 기능을 사용하게 되면 항공기가 어느 위치에 있던 초기 위치를 기준으로 경로 명령이 생성된다. 경로 명령은 최단거리를 가지는 원호-직선-원호로 구성되어있다. 경로 명령을 통해 생성된 경로를 따라 이동한 다음 활주로에 접근하도록 알고리즘을 설계하였다. 항공기의 다양한 초기 위치에 대한 경로 생성 알고리즘의 시뮬레이션을 통해 1차 검증을 하였으며 이를 기반으로 실제 비행시험을 수행하여 본 연구에서 제안한 알고리즘의 타당성을 실증적으로 검증하였다.
