The accelerometer bias errors result in an average constant offset plus an oscillatory component . 加速度計的偏置誤差形成一平均的常值偏離加上一振蕩分量。
The system was simulated in four kinds of conditions . the effect of gyro drift and accelerometer bias on the evaluation error of misalignment angles and attitude error was analyzed 并且分四種情況對系統(tǒng)進行了仿真,分析了加速計零偏和陀螺漂移對失準角估計誤差和姿態(tài)誤差的影響。
A batch least - squares maximum likelihood estimator is employed to calibrate the model coefficients of accelerometer and a polynomial post - fit method is used to establish temperature models of these coefficients . the temperature models of accelerometer bias and scale factor of accelerometer are established between - 20oc and 50 oc . after compensating the temperature error by using these models , the post - fit residuals of the accelerometer output have been improved to 10 ? 5 g , and the trend term of accelerometer changing with temperature basically vanished 采用最小二乘極大似然估計和多項式擬合的方法,分析加速度計靜態(tài)模型系數(shù)隨加速度計殼體溫度變化的規(guī)律,建立了- 20oc 50oc之間加速度計零偏和標度因數(shù)誤差的溫度模型,應(yīng)用該模型對加速度計溫度干擾進行補償,補償后,加速度計輸出的擬合均方根誤差一到二個數(shù)量級,并且基本上消除了加速度計輸出隨溫度變化的趨勢項,使得加速度計測量精度得到了明顯提高。
