Research of the Read-out Circuit for the Microgyroscope Using Double Modulating Sine Wave

XIAO Ding-bang,WU Xue-zhong,HOU Zhan-qiang,CHEN Zhi-hua,LI Sheng-yi(School of Mechatronic Engineering and Automation,National University of Defense Technology,Changsha 410073,Hunan,China)  
The vibration signals of the microgyroscope's mass on the driving axis as well as the detecting axis were modulated by two sine carrier waves with different high frequencies,so they were distinguished with the sine driving wave on the frequency spectrum,and finally the coupling noise could be reduced.That mass was exciting to oscillate with fixed amplitude on the driving mode by phase control and DC auto gain control.The oscillations on the driving and detecting axis were picked up by synchronous demodulator,and then the angular rate was obtained through secondary demodulation.A microgyroscope with this read-out circuit was tested and the results show that its scale factor is 38 mV/(°)·s-1,and its linearity is 0.8%.
