针对激光陀螺惯导的温度补偿,将影响激光陀螺零偏的各种可能的变量作为零偏补偿的状态变量,利用逐步回归分析方法,挑选出对零偏贡献较大的显著变量,建立精准的数学物理模型,并对实测的激光陀螺进行温度补偿建模。结果表明,温度变化率以及与温度的交叉积对温度补偿模型的影响不显著,得到的温度补偿模型可以对陀螺的零偏进行实时补偿,提高了陀螺的精度。
Aiming at the temperature compensation of laser gyroscope’s inertial navigation, various possible variables that affect the zero bias of the laser gyro are taken as the state variables of offset compensation. By using the stepwise regression analysis method, significant variables contributing to zero offset are selected, and precise Mathematical physics model, and the measured laser gyro temperature compensation modeling. The results show that the temperature change rate and the cross product with temperature have no significant effect on the temperature compensation model. The obtained temperature compensation model can compensate the gyro zero bias in real time and improve the accuracy of the gyro.
