| 摘 要： | 针对光纤陀螺随机误差信号特点,在分析其一般时间序列模型的基础上,将AR建模方法运用于随机误差信号的建模,得到陀螺随温度变化的真实趋势,然后利用数学方法建立陀螺的动态温度误差模型,对陀螺的输出进行实时补偿.经过仿真分析表明,通过以上方法的处理后,陀螺在-20℃～50℃全温范围内的零偏极差不超过0.2(°)/h,大幅度提高了陀螺的精度性能.

| Abstract: | Aimed at the characteristic of general time-sequence model of Fiber Optic Gyroscope(FOG) random error,the random error of FOG is analyzed by using the AR model in the time sequence method and dealt with by using least squares method.Moreover,The model of FOG drift with temperature can be described by using mathematical algorithms if the random error can be eliminated.The output of FOG can be compensated by using this method.The simulation shows that the method is effective and sensitive to detect fault,and ... |
