| 摘 要： | 针对再入飞行器的捷联惯性仪表误差模型不能满足“天地一致性”,导致了在地面试验环境下标定的仪表误差模型不是真实飞行环境下的误差模型。提出了按照再入飞行器的纵向过载变化大小对惯性仪表误差进行分段辨识和分段补偿的方法,以提高再入飞行器的制导精度。最后通过计算机仿真试验验证了此方法的正确性,为实际应用提供了理论依据。

| Abstract: | In view of the difference between the strapdown inertial instrument error parameters in the ground experiment environment and in the flight environment, the approach is presented to identify strapdown inertial instrumental error models and compensate the error in the segmented sections corresponding to the change of vertical acceleration of reentry aircraft.It can improve the guidance precision of high-speed reentry aircraft.The simulation results demonstrate the accuracy of segmented error compensation method. |
