英文摘要	A novel electrostatic force feedback approach is presented for extending the bandwidth of a mode-matching vibratory microgyroscope. A 0.02 Hz mode-mismatch gyroscope is achieved by applying a DC voltage of 26 V to the squeeze-film combs to adjust the stiffness of the sense mode. Sweep-frequency tests demonstrate that the open loop frequency response is close to a one-order system with a bandwidth of 7.9 Hz, which agrees well with the theoretical simulation. Moreover, both experiment and simulation results show that the bandwidth can be extended to about 94Hz from 7.9Hz after adopting an electrostatic force feedback control. ? 2012 IEEE.; EI; 0
