Abstract
An oscillator is oscillated at a predetermined oscillation frequency. A detecting unit exerts Coriolis force on the oscillator. A repetitive control system applies an external force to the oscillator so as to cancel out the Coriolis force to achieve an angular velocity measuring operation at a high sensitivity and a high S/N ratio.
