民用飞机IRS冗余配置下融合算法研究

Research on Civil Aviation Fusion Arithmetic with Redundancy IRS Configuration

为了确保民用飞行的安全,大型民用飞机一般配备冗余的导航系统,如A320一般装有三套IRS。如何利用冗余的传感器信息提供最重要的位置信息,成为民用飞机飞行管理系统亟待解决的关键技术。本文对冗余配置下如何进行三套IRS的融合进行了研究,提出了基于历史信息获取最佳混合位置的方法,并通过仿真分析验证了算法的有效性,为FMS导航功能关键技术的实现提供了理论基础和技术支持。

In order to insure civil aviation safety, large civil aircraft is usually equipped with redundancy navigation system. How to make full use of the redundancy sensor to supply the most important position becomes key technique for the Flight Management System. This paper presents methods to fuse the measurement of the three IRS and brings forward a method to obtain the best mixed position based on historical information. In order to validate the validity of the arithmetic, simulation and analysis are carried out. The arithmetic research will provide theory basic for the realization of Flight Management System.
