本文针对惯性测量组合当中的加速度计误差模型自标定问题,提出了一种基于多加速度计组合的测试方法。该方法以重力加速度g0的幅值平方作为参考基准来标定误差系数,使得标定精度不受转角定位误差的影响。采用三个相互正交的加速度计输出平方和作为观测信息,建立了g02观测误差辨识模型方程。该测试方法有效提高了加速度计的测试精度。
In this paper, aiming at the problem of self-calibration of accelerometer error model in inertial measurement combination, a test method based on multi-accelerometer combination is proposed. The method uses the square of the amplitude of gravity acceleration g0 as a reference to calibrate the error coefficient, so that the calibration accuracy is not affected by the angular positioning error. Using three orthogonal quadrature output of the accelerometer as the observation information, the establishment of a g02 observational error identification equation. The test method effectively improves the accuracy of the accelerometer test.
