Modelling and simulation of a miniaturized gyrometer

Abstract

The paper presents theoretical and numerical study of a MEMS vibration gyro based Coriolis effect. Two configurations of the gyro are modeled and simulated here: 1) with assumed control on the excitation axis (a simplified configuration used to validate the second one); and 2) gyro controlled on the excitation axis. Shown are: general dynamic equations of the gyrometer, mathematical models ant the resulted block diagrams for the two configurations, the control strategy for the second configuration, software implementations of the models and numerical simulations results.
