基于光纤陀螺仪的信号补偿

光纤陀螺仪是目前广泛使用的一种惯性仪器, 但在使用过程中仍然会遇到有很多问题. 光纤陀螺仪在使用过程中由于光纤陀螺仪内部元器件构造、材料的使用、以及元器件的精度等因素, 会产生一些误差, 如启动温度、零漂、刻度因子等. 同时在使用的过程中受外界的环境干扰也会使光纤陀螺仪产生误差, 如受外界的振动, 环境温度变化等. 通过分析研究光纤陀螺仪的原理和输出信号, 建立误差补偿模型, 对误差进行补偿分析. 应用分段平均选点法补偿了由于温度变化在信号中产生的线性趋势项, 以及使用平滑滤波算法对光纤陀螺仪输出信号进行

Signal Compensation Based on Fiber Optic Gyroscope

The fiber optic gyroscope is an inertial instrument, which is used widely, but there are still many problems in the application of the FOG. The disadvantages of the fiber optic gyroscopes such as such as temperature effect, non-linearity of scale factory and disturbance. This paper analyses the principle and the signal output of the fiber-optic gyroscope. It establishes the compensate model of nonlinearity error and linearity error, uses signal processing algorithm and signal filtering algorithm to compensate variety of error. The signal processing algorithm is proved to be effective through actual experiments.
