METHOD AND INERTIAL DEVICE FOR DETERMINATION OF ROTATION SPEED OF AN AXISYMMETRIC VIBRATING SENSOR

摘要

The invention relates to a method for determining the rotation speed of a second-order axisymmetric vibrating sensor, that comprises the steps of: carrying out an evaluation of the rotation speed consecutively for a number N of the vibration positions relative to the electrodes, the positions being geometrically offset by a predetermined angle and the vibration being moved from one position to another by the application of a precession control using a preset scale factor; calculating an average (15) of the rotation speed estimations in the N positions, the number N of positions and the angle separating the positions being such that the average of the evaluations can be used for removing an amplitude of at least one harmonic of the vibration.
