Method for electronically tuning the readout vibration of a coriolis gyroscope
First Claim
1. A method for electronic tuning of the frequency of the read oscillation to the frequency of the stimulation oscillation in a coriolis gyro, wherein the resonator of the coriolis gyro has a disturbance force applied to it such that a) the stimulation oscillation remains essentially uninfluenced, and b) the read oscillation is changed such that a read signal, which represents the read oscillation, contains a corresponding disturbance component, wherein the frequency of the read oscillation is controlled such that the magnitude of the disturbance component, which is contained in the read signal, is as small as possible:

Abstract
In a method for electronic tuning of the frequency of the read oscillation to the frequency of the stimulation oscillation in a Coriolis gyro, the resonator of the Coriolis gyro has a disturbance force applied to it such that the stimulation oscillation remains essentially uninfluenced. The read oscillation is changed so that a read signal that represents the read oscillation contains a corresponding disturbance component. The frequency of the read oscillation is controlled so that the magnitude of the disturbance component contained in the read signal is a minimum.
