Abstract:
(EN) An error compensation system for circular loitering guidance control of an unmanned aerial vehicle according to the present invention comprises: a flight control computer for outputting a circular loitering radius command (Rcmd) for an unmanned aerial vehicle, compensating circular loitering guidance control errors of the circular loitering radius command (Rcmd), and generating a compensated circular loitering radius command (R͂cmd); a control column driver (200) for driving a control column by receiving the compensated circular loitering radius command; an unmanned aerial vehicle flying under the control of the control column driver; and a navigation device for measuring a flight state of the unmanned aerial vehicle and transmitting the flight state to the flight control computer. Therefore, the present invention can eliminate circular loitering radius errors that are inevitably accompanied when an unmanned aerial vehicle circularly loiters by using a circular loitering command compensator, and thus can maintain a precise circular loitering radius to improve precision in unmanned aerial vehicle reconnaissance missions.
(FR) La présente invention concerne un système de correction d'erreurs dans une commande de guidage de rotation de maintien circulaire d'un aéronef sans pilote, ledit système comprenant : un ordinateur de commande de vol qui délivre une commande de rayon de rotation de maintien circulaire (Rcmd) pour un aéronef sans pilote, qui corrige des erreurs dans une commande de guidage de rotation de maintien circulaire selon la commande de rayon de rotation de maintien circulaire (Rcmd), et qui génère une commande de rayon de rotation de maintien circulaire corrigée (R͂cmd); un pilote de colonne de commande (200) permettant piloter une colonne de commande par réception de la commande de rayon de rotation de maintien circulaire corrigée; un aéronef sans pilote volant sous la commande du pilote de colonne de commande; et un dispositif de navigation permettant de mesurer un état de vol de l'aéronef sans pilote et de transmettre l'état de vol à l'ordinateur de commande de vol. Par conséquent, la présente invention peut éliminer les erreurs de rayon de rotation de maintien circulaire occasionnées de manière inévitable lorsqu'un aéronef sans pilote vole en maintien circulaire, à l'aide d'un correcteur de commande de rotation de maintien circulaire, et peut ainsi maintenir un rayon de rotation de maintien circulaire précis pour améliorer la précision lors d'une mission de reconnaissance réalisée par un aéronef sans pilote.
(KO) 본 발명에 따른 무인기 원선회 유도제어 오차 보상 시스템은 무인 비행체의 원선회 반경 명령 (Rcmd) 을 출력하여, 상기 원선회 반경 명령(Rcmd)에 대한 원선회 유도제어 오차를 보상하고, 보상된 원선회 반경 명령 (R͂cmd)을 생성하는 비행제어 컴퓨터; 상기 보상된 원선회 반경 명령을 수신하여 조종간을 구동하는 조종간 구동기; 상기 조종간 구동기(200)의 제어로 비행하는 무인 비행체; 및 상기 무인 비행체의 비행상태를 측정하여 상기 비행제어 컴퓨터로 상기 비행상태를 전송하는 항법장치;를 포함하여, 원선회 명령보상기를 이용해 무인항공기가 원선회 비행시 반드시 수반되는 원선회 반경 오차를 제거함으로써, 정밀한 원선회 반경을 유지하여 무인기 정찰 임무의 정확성을 높일 수 있는 효과가 있다.
