| 中文摘要: |
| 为减小光纤陀螺仪的误差,提高精度,需要对陀螺仪进行误差估计和补偿.为此建立了光纤陀螺仪的误差模型,用Allan方差对三轴一体化光纤陀螺的输出进行误差分析,辨识出各项随机误差系数,得到影响光纤陀螺性能的误差源,进而对三轴一体化光纤陀螺的研制提出改进意见. |
| 英文摘要: |
| In order to reduce errors in fiber optic gyroscopes(FOG) to improve its performance,evaluation and compensation should be the first step,so the error model of FOG is given.Allan variance method is used to analyze the output error characteristics of the three-axis integrative FOG.Each error coefficient is identified and then the error sources are gained.Furthermore,a suggestion on the manufacture of three-axis integrative FOG is provided. |
