An Improved Drive Circuit for Vibratory Microgyroscopes

JIANG Qing-hua,YUAN Wei-zheng,CHANG Hong-long,CUI Jin-qiang(Micro&Nano System Laboratory,Northwestern Polytechnical University,Xi'an 710072,China)  
Making vibratory microgyroscopes based on Coriolis principles vibrate at those nature frequency is the directly way to enhance those sensitivity and stability.The phase-lock loop is the widely used control scheme.Each part of the phase-locked loop including the micro-gyroscope has been modeled and linearized.Then the system transfer function deriven shows that there is a constant error between the input and the output.So an calibration module was added to the control loop to enhance the control accuracy.The experiments using a tuning fork vibratory microgyroscope was carried out.The results indicate that the sensitivity of the gyro was better than before.
