针对MEMS微机械陀螺的零偏随温度变化波动较大的特性,通过建立MEMS陀螺零偏随温度变化之间的误差模型,在温度范围为-20℃~60℃温箱试验下,分析MEMS陀螺的零偏输出变化,经去除野值后使用建立的误差模型对零偏进行补偿,结果表明,MEMS陀螺仪因温度引起的零偏从最大约为160°/h,经补偿后降至约为10°/h。该温度误差模型使MEMS陀螺的全温区零偏特性得到了一定程度的提升,为提高之后的导航精度打下基础,具有一定的工程价值。

For MEMS gyroscopes,biases characteristics always vary with temperature fluctuations. Through establishing error model between the temperature and the MEMS gyroscope biases,the biases outputs of the MEMS gyroscope are studied within a temperature range of -20 ℃ ~60 ℃. Via using the error model after removing outliers,results show that MEMS gyroscope biases caused by temperature have changed from approximately 100 °/h to approximately 10 °/h after compensations. Also biases in the whole temperature range have been improved to some extent,which would lay a foundation for improving the navigation accuracy.
