Abstract
In a gyroscopic system, a vibrating gyroscope is controlled in gyrometer mode in a control loop. The control loop corresponds to at least one current control for an operating parameter. In the control loop, a modified control to be applied to the gyrometer for said operating parameter is obtained () by introducing a sinusoidal interference into the current control. Then, the modified control is applied () to the gyrometer as the current control. A resulting measurement value () is determined. A sinusoidal interference () is calculated as a function of said measurement value. Lastly, on the basis of the measurement value, it is decided () whether to repeat the previous steps on the basis of the sinusoidal interference last determined.
