SOLID-BODY WAVE GYROSCOPE Russian patent published in 2003 - IPC

FIELD: gyroscopic instrument engineering, applicable for measurement of angles in control systems. SUBSTANCE: gyroscope has a resonator in the form of an axially symmetric thin-walled component, at least one electrode of the resonator, secured on the resonator in the form of an axially symmetric thin-walled component, at least one electrode of the resonator, secured on the resonator surface, case attached to which is the resonator and a great number of transducer electrodes, control electrodes positioned in close vicinity of the resonator electrodes, electronic control unit containing devices for stabilization of the oscillations amplitude, suppression of quadrature oscillations, calculation of the angle. The electronic unit has master and input units. The master unit is connected to the control electrodes and comprises a device for generation of the reference voltage being a time function of square pulses with a constant component equal to zero. The device for generation is connected to the resonator electrode. The input unit is connected to the electrodes of the transducers and has devices for reversal of the polarity of the output signals, synchronized with the reversal of the sign of the reference voltage. EFFECT: enhanced precision of the gyroscope. 2 cl, 2 dwg
