摘　　要：提出利用载机不同飞行状态下弹载子惯导陀螺仪与机载主惯导陀螺仪输出角速度差异对机翼弹性变形的AR模型参数进行在线辨识,采用一种改进的卡尔曼滤波算法对模型参数进行估计,利用信息对准模型的适应性进行检验。结合速度加姿态传递对准模型,建立了考虑机翼弹性变形的传递对准模型。仿真试验验证了该在线建模方法的有效性,在传递对准中考虑机翼弹性变形模型,可以有效地降低机翼弹性变形对传递对准的影响。The AR model was used to model the wing flexure. The model parameters ware identified through using the discrepancy of missile-borne strapdown inertial navigation system＇s gyroscopes＇ outputs and that of the master SINS. The information criterion was adopted to test the model＇s applicability. The online wing flexure model was added to the rapid transfer alignment model to decrease the influence of wing flexure. Simulation results demonstrate the effectiveness of the modeling method. Considering the wing flexure model in transfer alignment can reduce the influence of the wing flexure effectively.
