FIELD: gyroscope engineering. ^ SUBSTANCE: method comprises exciting vibration along the axis of primary vibration by feeding alternative voltage to the electrodes of the comb motor, generating the first signal proportional to the velocity of movement of the movable mass along the axis of the primary vibration, generating the second signal from the signal of the velocity pickup along the axis of the secondary vibration proportional to the movement of the movable mass along the axis of the secondary oscillation, multiplying the second signal by the signal that is in phase with the first signal, extracting the third signal proportional to the low-frequency component of the production of these signals, extracting the fourth signal proportional to the amplitude of the first signal, and generating fifth signal by normalizing the third signal by the fourth signal. The micromechanical gyroscope comprises movable mass mounted on the two-axle resonance suspension, capacitive transducers arranged along the axes of the primary and secondary vibrations, comb motor, device for exciting vibration of the movable mass, amplifier connected with the output of the capacitive pickup located at the axis of the secondary vibration, phase rotator, demodulator whose inputs are connected with the output of the amplifier and output of the phase rotator, amplitude detector whose input is connected with the output of the capacitive pickup arranged along the axis of the primary vibration, and divider whose outputs are connected with the output of the demodulator and output of the amplitude detector. ^ EFFECT: enhanced precision. ^ 5 cl, 8 dwg |
