| 摘 要： | 给出了一套弹性体上惯性测量系统的传递对准方案。该方法只采用角速度陀螺作为测量元件,能够对传感器误差进行补偿,并且可给出两套测量坐标系失配角的可靠估计。本文应用弹性力学的模态法建立机翼的运动方程;应用自适应Kalman滤波器在线估计由空气动力诱导的广义外力。

| Abstract: | An approach to transfer alignment of inertial units on elastic body is proposed in this paper. In this approach, the angular velocity gyros are used as inertial units, the error of inertial units (angular velocity gyros) can be complemented, and the misalignment between two menial units can be estimated with high accuracy. The main contribution of this paper can be summarized into (1) the use of modal method in elastic mechanics to establish the motion equation of wing of the airplane, and (2) the use of adaptive Kalman filter to estimate the generalized force derived from the air. An example proves that the approach is effective. |
