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. Aiming at the characteristics of random error signal of fiber optic gyroscope, based on the analysis of its general time series model, the AR modeling method is applied to the modeling of random error signal to get the true trend of gyroscope with temperature change. Then, Temperature error model to compensate the gyroscope’s output in real time.After the simulation analysis shows that the gyroscope’s zero deviation in the whole temperature range of -20 ℃ ~ 50 ℃ does not exceed 0.2 (°) / h after the above method, Dramatically improve the accuracy of gyro performance.
