光纤陀螺零偏温度补偿的实验研究
Research on temperature compensation for fiber optic gyro
【摘要】 为光纤陀螺因温度效应而产生的零偏提供一种补偿方法,针对自行研制的光纤陀螺仪的零值漂移,根据实验数据,建立一种温度补偿模型,采用最小二乘法拟合计算出所需的修正系数对其预测补偿.补偿结果表明:光纤陀螺经模型补偿后零偏基本可以减少一个数量级,并进一步提高了零偏稳定性,补偿效果明显.
【Abstract】 Based on the temperature effect of fiber optic gyro,a method of compensating the bias is proposed in the paper.According to lots of the experiment data,a new temperature compensating model is provided.The predicted compensation adopts least square fitting to compute the modified coefficients.The results of compensation show that its bias reduces to one tenth of the original.The bias stability is also enhanced.Therefore,the approach is feasible.
