Abstract

The invention relates to a force feedback control system and method for a hemispherical resonator gyroscope and belongs to the technical field of control of inertial instruments; the control system and method are applied to a force feedback working mode of the hemispherical resonator gyroscope, and the method is a way to implement a hemispherical resonator gyroscope control method. By using a hemispherical resonator gyroscope force feedback circuit designed by using the method, it is possible to synchronously track the operating frequency of the hemispherical resonator gyroscope, demodulate the amplitude and phase of gyroscope wave node signals, and modulate high-voltage signals of force feedback control signals; in addition, not by modifying the configuration of a controller but just correcting controller parameters, it is possible to meet different environmental application needs of the hemispherical resonator gyroscope.
