【摘要】 从实用的角度出发,给出了微小型飞行器的航向系统(包括航向测量和航向控制)体系结构.设计了地磁航向、捷联航向、GPS航向等3种常用的航向测量手段在微小型系统中的实现方案,分析了其各自的优、缺点,提出了一种实用的、基于数据融合的航向获取方法.在航向测量的基础上,又设计了针对微小型飞行器的航向控制方案,并应用于某小型固定翼飞行器的飞行控制系统中.进行了自主飞行试验,取得了预期的试验效果.更多还原

【Abstract】 A new heading system(including heading measurement and heading control) framework is presented for Micro Air Vehicles(MAVs) from the viewpoint of practical applications.Then,an implementation scheme is designed in which three most popular heading measurement methods,i.e.,magnetic heading,strapdown heading and GPS heading,are integrated into a mini system.The strong and weak points of these methods are analyzed,and a practical heading approach based on data fusion is provided.A heading control scheme for MAVs is designed based on heading measurements,which is applied to the flight control system of a mini fixed wing aircraft.Some desired results are obtained in autonomous flight tests.更多还原
