加速度计温度补偿模型的研究

Research on Temperature Compensating Model for Accelerometer

研究了加速度计的温度特性.通过温度实验,分别得到了加速度计的零偏、标度因子和IF转换电路的温度补偿模型,并在捷联系统中得到应用.结果表明,得到的模型可以有效地补偿加速度计温度误差,通过温度补偿,缩短了系统的预热时间,提高了系统的精度.

Based on temperature experiment, the temperature characteristic of accelerometer has been studied. The temperature compensation model of accelerometer＇s output has been gained, and it has been applied to SINS. It has been shown that these models can compensate error of the accelerometer effectively. The SINS＇s precision can be improved, and the warm-up time can be shortened by temperature compensation.
