机载显示系统中会用数值或图示的方式实时显示飞行过程中飞机各参数,而机载显示系统中数据的平滑与否,直接影响飞行员的操作压力以及对于飞机状态判断的准确性与否。本文分析了迟滞,滑动平均,低通滤波以及多参数的最优估计这四种显示数据平滑方法的适用场景与各自的优缺点。
Airborne display system will be displayed in numerical or graphical way real-time display of the aircraft during flight parameters, and airborne display system data smoothing or not, directly affect the pilot’s operating pressure and the aircraft state to determine the accuracy or not . This paper analyzes hysteresis, moving average, low-pass filtering and multi-parameter optimal estimation of the four display data smoothing method for the application scenarios and their advantages and disadvantages.
