We report on a new approach allowing parameters identification of a closed loop controlled microelectromechanical Coriolis Vibratory Gyroscopes (CVG) driven in a nonlinear regime. Since the drive mode amplitude and phase of the gyro module are both controlled, common nonlinearity identification tech...
