Research on the Temperature Compensation Method for Micro Inertial Measurement Unit

Abstract:

In this paper, the temperature characteristics of Micro Inertial Measurement Unit (MIMU) were studied for improving its stability. The temperature error model was built on the basis of analyzing its temperature characteristics. The model combined zero bias and calibration factors for MEMS accelerometers and gyros with multiple variables and it was optimized by the stepwise regression method. Meanwhile, combined with Kalman filtering theory, using Kalman filtering to reduce the noise of the temperature measurement could further improve the compensation accuracy and measurement accuracy.
