Systems and methods for calibrating and correcting the accelerometer having a bias instability

摘要

I discloses a method for determining a compensation factor of the accelerometer to present a bias transients. The method includes a step of estimating the bias from the measured acceleration cumulative meter output, determining a corrected accelerometer output, and determining the compensation factor of the accelerometer. Accumulated bias is estimated by comparing the low acceleration output values ​​before and after the short-term high acceleration period. In order to determine the correct acceleration value, cumulative bias is subtracted from the value that is obtained during high acceleration.
