The accelerometer bias errors result in an average constant offset plus an oscillatory component . 加速度计的偏置误差形成一平均的常值偏离加上一振荡分量。
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 并且分四种情况对系统进行了仿真,分析了加速计零偏和陀螺漂移对失准角估计误差和姿态误差的影响。
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 采用最小二乘极大似然估计和多项式拟合的方法,分析加速度计静态模型系数随加速度计壳体温度变化的规律,建立了- 20oc 50oc之间加速度计零偏和标度因数误差的温度模型,应用该模型对加速度计温度干扰进行补偿,补偿后,加速度计输出的拟合均方根误差一到二个数量级,并且基本上消除了加速度计输出随温度变化的趋势项,使得加速度计测量精度得到了明显提高。
