METHOD OF DETERMINING A SPEED OF ROTATION OF AN AXIALLY SYMMETRICAL VIBRATING SENSOR, AND A CORRESPONDING INERTIAL DEVICE

摘要

The method of determining a speed of rotation of an axially symmetrical vibrating sensor having a vibrating member associated with control electrodes and with detection electrodes for generating vibration presenting an elastic line possessing periodicity of order n and having a position that is variable as a function of the rotation of the sensor, the method comprising the steps of: performing evaluation of the speed of successively for a predetermined number of positions of the vibration relative to the electrodes; the positions being geometrically offset relative to each other and the vibration being moved from one position to another by applying a precession command using a pre-established scale factor; determining a speed of rotation in function of the evaluations. The device for implementing such method.
