Структура и характеристики волнового микромеханического датчика угловой скорости с кольцевым резонатором
Abstract
The features of dynamics and oscillation control of the ring resonator in a micromechanical gyroscope are considered. Inert properties of elastic vibrations are used in this gyro. The case when the resonator oscillations are excited according to the scheme of a self-excited oscillator with additional contour to stabilize amplitude of elastic vibrations is under study. In order to reach the required dynamic characteristics of the gyro, it is suggested that the feedback by the speed of the resonator ring radial travels in the zone, where readings are taken, be used in the measuring chan-nel. The procedure for getting a model of envelopes of physical oscillations in the form of differential equations is presented. This model is a convenient instrument to study characteristics of direct-measurement and compensatory type gyros.
