摘要
光纤陀螺随机漂移是捷联惯导系统的主要误差源,对其建立一个精确的、适用的模型有利于减小光纤陀螺漂移,提高系统精度。本文根据时序建模理论,利用Matlab中的自带函数,建立了光纤陀螺随机漂移模型。Matlab在光纤陀螺漂移建模中的应用,避免了传统编程建模的繁琐,简化了建模的计算过程,大大减小了工作量,提高了建模效率。
FOG random drift is the great error source of SINS, it should be modeled accurately to reduce it and to improve the precision of system. Based on the theory of time series analysis, several functions of Matlab are used in modeling FOG random drift, which simplifyies the processs of calculation and improves the efficiency of modeling.
