摘要
为了对二频机抖激光陀螺的零偏进行补偿,研究了PZT电压与温度之间的关系。通过大量的重复性高低温实验,利用最小二乘法证明了PZT电压与温度的线性关系,并得到了拟合直线表达式,并分析了利用PZT电压对零偏的补偿效果。结果表明,PZT电压与温度具有较好的线性关系,利用PZT电压对陀螺的零偏进行补偿,可以提高陀螺的精度。
For the sake of compensating the bias of mechanically dithered RLG（ring laser gyro）, the relation between PZT（Piezoelectricity） voltage and temperature has been studied. It has been shown that PZT voltage is proportional linearly to the temperature in the help of the method of least square via lots of highlow temperature experiment repeated, and the linear expression is achieved, and the compensating effect of PZT voltage to bias. Because the RLG＇s bias is affected by the temperature. The RLG＇s precision can be improved by temperature compensation using PZT voltage.
