## Modeling and identification of random drift for FOG

• 摘要: 随机漂移是光纤陀螺的主要误差,建立数学模型在输出中补偿是抑制该项误差、提高光纤陀螺精度的有效方法.光纤陀螺静态输出为随机过程,对该随机过程的平稳性和正态性进行分析,拟合趋势项、周期项并补偿,使其成为平稳随机序列.采用时间序列分析法建立光纤陀螺随机漂移模型,根据随机漂移自相关和偏相关系数的特性辨识模型的类型和阶数,利用最小二乘方法估计模型参数,得到光纤陀螺随机漂移模型为AR(2).对陀螺输出数据补偿,检验模型的适用性.结果表明,该模型具有很好的适用性,能够有效抑制随机漂移,提高光纤陀螺精度,可以作为惯导系统卡尔曼滤波器状态变量的数学模型.
