Influence of external shocks and internal noises on the resonant frequency tracking system in Coriolis vibratory gyroscope

Abstract

Resonant frequency tracking system that ensures rapid capture and track of frequency when switching on the gyro at any temperature from the working temperature range in Coriolis vibratory gyro are proposed and analyzed in this work. The problems of external shocks and internal noises influence suppression on the performance of resonant frequency tracking system, built on the basis of phase lock loop by tuning PIDF controller coefficients, used in feedback control loop of the tracking system are investigated.
