<p>PURPOSE: A vibration control method of a dual mass gyroscope is provided to control the fixed frequency of two mass devices and to have the two mass devices of the uniform amplitude and resonant frequency and vibrate reversely. CONSTITUTION: A first mass element between two mass elements(41a) vibrates with resonant frequency having the constant amplitude. The power, in which the size is same as the size of power to operate the first mass element and the phase is opposite, is applied in the second mass element. The power applied in the second mass element and the oscillation frequency of the second mass element due to the same are compared. The resonant frequency of the second mass element is adjusted based on a comparison result and the resonant frequency of the first mass element is corresponded with the second mass element. The amplitude of the first mass element and the amplitude of the second mass device are corresponded.</p> |
