Abstract

The stability and accuracy of the drive mode are important for the performance of vibrating MEMS gyroscope. At present, the PI-like controller is always used in the control of the drive mode of vibrating MEMS gyroscope. The PI-like control has good effect on rejecting the literal disturbance, but it can’t reject the time-dependent disturbance well. The disturbance for the MEMS gyroscope is so uncertain that the stability and accuracy of the PI-like control for the gyro are comparatively low. In this paper, an ADRC method for vibrating MEMS gyroscope drive is introduced, and it is proved that this method can rapidly and stably control the MEMS gyro drive mode by simulation and comparing with the PI-like method.
