Abstract

The application discloses a kind of hemispherical resonator gyro amplitude auxiliary maintenance method and device, hemispherical resonator gyro, amplitude auxiliary maintenance method includes: after the hemispherical resonator gyro is started, the voltage of all electrodes of hemispherical resonator gyro is 0, the output of the amplitude control loop of hemispherical resonator gyro is converted into AC signal and then switched to the high voltage electrode of hemispherical resonator gyro, while the DC signal applied on high voltage electrode remains unchanged.The application multiplexes high voltage electrode as ring electrode to assist in maintaining the amplitude of hemispherical resonator gyro, and the improved circuit structure is simple and the traditional control algorithm can be compatible on software.
