【摘要】 研究了应用长自回归估计法进行光纤陀螺零漂数据模型的参数估计,利用卡尔曼滤波算法进行参数的精估计,建立了光纤陀螺零漂数据的ARM A模型。研究结果表明,所建的光纤陀螺ARM A模型较传统的AR模型具有更高的精度,光纤陀螺随机漂移ARM A模型可分解为两个独立的时间相关的一阶马尔可夫过程。更多还原

【Abstract】 The quadrature estimation of athwart function had been adopted to parameter estimation of FOG,and the Kalman filter principle had been used for accurate estimation,and the ARMA model of FOG drift data had been founded.The result have been indicated that FOG has more precise than that of AR model,and the stochastic drift ARMA model of the FOG can be decomposed to two absolute and time correlative one rank markov process.更多还原
