本文报道了一种全差分调频陀螺，其中叠加的顺时针（CW）和逆时针（CCW）模式在单个谐振器上独立控制。CW和CCW模式检测器被开发用于同时控制谐振器上的两个模式。提出了一种频率和品质因数失配补偿方法，使这两种模式完全正交化。提出了一种具有良好的角速率与频差线性关系的调频陀螺工作原理。标度因子的温度系数小至-52 +/-136 ppm/℃。标度因子和偏倚在700小时内保持稳定，漂移分别小于0.062 +/- 0.100 ppm/hr和31 +/- 121 ppm/hr。
This paper reports a fully differential frequency modulated (FM) gyroscope where the superposed clockwise (CW) and counter clockwise (CCW) modes are independently controlled on a single resonator. The CW and CCW mode detectors were developed to control both modes simultaneously on the resonator. A frequency and quality factor mismatch compensation method was developed to perfectly orthogonalize these two modes. A FM gyroscope operation with excellent linearity between applied angular rate and frequency difference was demonstrated. The temperature coefficient of scale factor was as small as -52 +/- 136 ppm/degrees C. The scale factor and bias were stable over 700 hours with the drift less than 0.062 +/- 0.100 ppm/hr and 31 +/- 121 ppm/hr, respectively.
