摘要
以一种典型的速度加姿态匹配传递对准模型为例,系统地分析和介绍3种延时误差补偿方法:外推―滤波法、滤波―更新法和建模补偿法。为验证和比较这3种方法的补偿效果,采用S行飞行轨迹进行计算机仿真。仿真结果表明,在该种飞行条件下,3种方法都能够有效地减小传递对准延时误差,其中滤波―更新法对延时误差的补偿最为彻底。
Taking a typical transfer alignment model with velocity plus attitude matching as example,three time-delay error compensation methods,namely extrapolating-filtering method,filtering-updating method and modeling method,are systemically analyzed and introduced.To validate and compare their compensation performance,computer simulation is carried out in which a S-shaped flight path was adopted.Simulation results indicate that under this flight condition all three methods could decrease time-delay error of transfer alignment effectively,where filtering-updating method can compensate for the error most thoroughly.
