闭环光纤陀螺的输出误差特性研究

Output Error Characteristics of Closed-loop FOG

针对工程实际的需要,通过对闭环光纤陀螺模型参数的对比研究,分析了闭环光纤陀螺零偏稳定性的变化,并利用Allan方差具体分析了闭环光纤陀螺的输出误差特性中的角随机游走、零偏不稳定性、速率漂移斜波等的变化,从中找出规律性的关系。

A comparative study on closed-loop FOG parameters is conducted to analyze the variation of the bias stability. Allan variance method is used to analyze the changing of the angle random walk, the bias instability and the rate ramp, which are shown in the output error characteristics of closed-loop FOG. The analysis results indicate the corresponding relations between the model parameters and the error characteristics.
