METHOD FOR CONTROLLING THE PRECESSION OF A VIBRATING GYROSCOPE

摘要

The invention proposes a method for controlling the precession of a gyroscope (1) comprising a support (2) and a resonator (3), the support (2) being movable in a platform reference frame and fixed in a measurement reference frame, the method comprising generating (101) a first control signal suitable for rotating the resonator (3) relative to the support (2) in two opposing directions of rotation during a first period, the method being characterised by the following steps: - receiving (104) data concerning the relative positioning (Tpm) between the measurement reference frame and the platform reference frame, - calculating (105) a second control signal to be generated during a second period from the first control signal and positioning data, the second control signal being chosen in such a way as to minimise a mean of angular errors accumulated in angular measurements acquired by the gyroscope (1) during the whole of the first and second periods, the angular errors being expressed in the platform reference frame.
