飞机飞行参数数据预处理方法研究

摘要

The processing of flight data is very important for the aircrafts` safety.However, error on flight data can significantly influence the processing results.On analyzing the basic compositions of error on flight data and the elimination methods of unconventional error on flight data, error is classified and four methods of different values rejection and missing data estimation are presented according to different type flight data.The result of the simulation shows that the four methods greatly improve the effectiveness and can be convenient for post-processing of flight data.%飞行参数数据的处理对飞机的飞行安全至关重要,而飞行参数数据的误差会显著影响飞行参数数据处理的结果.分析飞行参数数据误差的基本组成,研究飞行参数数据误差中非常规误差的消除方法,给出了四种适用于对不同类型飞行参数数据进行异值剔除与缺失数据估计的方法,仿真结果表明这四种方法大大提高了飞行参数数据的有效性,使飞行参数数据后期处理更便利.
