摘要
针对FADS系统引气管路压力传递存在的延迟误差,采用波动方程理论根据变管径引气管路的物理模型建立了压力传递的数学建模,对由不同直径、长度的管路串联而成的变管径引气管路压力传递延迟特性进行了仿真分析,获得了不同直径、长度的仿真分析结果。最后,提出了基于卡尔曼滤波器的变管径管路压力传递延迟补偿算法。计算机模拟试验的结果表明,引气管路压力延迟补偿算法可减小引气管路压力传递延迟时间、有效补偿压力传递延迟误差。
A pressure transmission model of unequal-diameter pneumatic tube for FADS （Flush Airdata Sensing） system is built up according to wave equation theory. The simulation on pneumatic lag charac- teristic is conducted on the pneumatic tube with different diameter pipe length on the series, and a com- pensation algorithms based on the kalman filter is put forward. The results of computer simulation tests show that the compensation algorithm of pneumatic lag error can shorten the delay time of pressure trans- mission and compensate the error of pneumatic lag effectively.
