Improvement in the Method for Bias Drift Compensation in Micromechanical Gyroscopes

Abstract

In this paper an improvement in method is proposed for the compensation of the bias drift in micromechanical gyroscopes by a change in the sign of the measured quantity. A general model of external factors of influence is proposed that must be taken into account when the method is applied. An information-measurement system is developed and experimental data are taken from two commercial sensors. The derived results are showing considerable improvement in the long-term bias stability when the proposed improvement in method is applied.
