基于Allan方差的MEMS陀螺仪随机误差分析方法
Random Error Analysis Method for MEMS Gyroscope Based on Allan Variance
摘要
Abstract
The random drift error of MEMS gyroscope is the main reason to restrict the precision of inertial navigation.In this paper, the main source of random drift error of MEMS gyroscope and the performance parameters of various errors are obtained by Allan variance analysis.This method lays the foundation for analyzing the performance parameters and improving the precision of inertial navigation.In this paper, the definition of Allan variance and the relationship between the random error and Allan variance are introduced.Finally, the MEMS gyro component is built, and the gyro data is collected by high precision turntable experiment.The Allan variance analysis is used to obtain the performance indexes of MEMS gyro, and the feasibility of the method is verified.关键词
