The dynamics of a vibrating ring microgyroscope resonator with open-loop and closed feedback is investigated. We use a mathematical model of forced oscillations for thin elastic resonator, taking into account the nonlinearity coefficient, uneven stiffness, difference in Q-factors and control impact parameters. Using the Krylov–Bogolyubov averaging method, the resonator dynamics in slow variables measured by microgyroscope electronics has been investigated. Formulas with algorithmic compensation of the above defects for determining the angular velocity of the resonator under nonlinear oscillations and without feedback have been obtained. Control signals taking into account the defects are presented for feedback of the microgyroscope operating in the compensation mode of the angular velocity sensor. Numerical modeling of angular velocity determination in the operation modes considered has been carried out.
Keywords: vibrating ring microgyroscope, angular velocity sensor, nonlinear oscillations, drift compensation.
