APPROACH FOR CONTROL REDISTRIBUTION OF CORIOLIS VIBRATORY GYROSCOPE (CVG) FOR PERFORMANCE IMPROVEMENT

摘要

Disclosed is a Coriolis vibratory gyroscope (CVG). The CVG includes: multiple first operators electrically coupled to a vibratory member and installed around a driving shaft of the CVG, wherein the first operators enable a vibratory member to vibrate in a first oscillation mode and a control unit to obtain a control signal and can operate to provide a sufficient voltage to maintain the vibration; multiple second operators electrically coupled to the vibratory member and arranged around a sensing shaft of the CVG, wherein the second operators detect a voltage based on a second oscillation mode of the vibratory member, which is cause by the rotation of the CVG around a rotation shaft, and providing a sufficient counter-balancing signal to null the voltage based on the second oscillation mode. The control unit can operate to determine a rotation rate of the CVG partially based on the counter-balancing signal.
