MEMS陀螺漂移误差抑制方法研究
A Research on Method of MEMS Gyroscope Drift Error Inhibition
摘要
Abstract
Drift error of MEMS gyroscope has a great effect on the accuracy of Inertial measurement system.In order to solve this problem to introduce rotation modulation error suppression method and Kalman filter method,the constant drift error is inhibited by using rotation modulation and the random drift error is reduced by using Kalman filtering. From simulation and experimental verification the attitude Angle error of inertial measurement system,before and after the modulation and the filter are compared,it is show that rotation modulation and Kalman filtering can reduce constant drift error and random drift error,and the attitude angle error caused by two of this kind decrease obviously. The measurement accuracy of the inertial navigation system has a distinct improvement.关键词
