A method of compensating for a zero error of a Coriolis gyro is provided to distinguish misalignments of stimulating forces between a real read oscillation and a real stimulating oscillation causing a read oscillation signal the subject of zero error when the read oscillation signal is extracted by controlling a compensation signal to minimize an auxiliary signal. A method of compensating for a zero error of a Coriolis gyro comprises the steps of: modulating the frequency of a read oscillation; demodulating the output signal from a rotary rate control loop or from a quadrature control loop of the Coriolis gyro at the same time the read oscillation is modulated to obtain a zero error measuring auxiliary signal; and generating a compensation signal and transmitted to an input of rotary rate control loop or to an input of the quadrature control loop, and the compensation signal is controlled so as to minimize the size of the auxiliary signal as much as possible.
