摘要 针对光纤陀螺随机漂移的非线性,提出了运用一类非参数ARMA模型(FARMA模型)对光纤陀螺漂移数据进行建模。依据某型光纤陀螺的实测数据,通过比较选择了FARMA(2,1,1)模型作为该型光纤陀螺随机漂移数据的模型。在此基础上对模型进行了适用性检验,同时对该模型的拟合结果进行分析,结果表明FARMA(2,1,1)模型能够更好的描述光纤陀螺随机漂移。 According to nonlinearity of fiber-optic gyro random drift,a nonparametric ARMA model(FARMA model) was used in modeling of fiber-optic gyro drift data.Based on data by a type of fiber-optic gyro,after comparison,the FARMA(2,1,1) model of the fiber-optic gyro drift data was chosen.On the basis of applicability test of the model and analysis on the model's fitting result,the result indicated that the FARMA(2,1,1) model can better describe the fiber optic gyro random drift.
