介绍了一种融合滚转率和偏航率两种信息的微机械陀螺（角速率传感器）的工作原理。输出正弦波频率是旋转载体滚转率，这是很容易检测到的，但幅度取决于滚转率和偏航率。否则，不可避免地会存在制造缺陷，这就导致不同陀螺的标度因数不可能完全相同。为了解决这些问题，提出了一种简单的方法。结果表明，输出信号与横摆角速度呈线性关系，减小了横滚角速度变化对输出信号的影响。此外，不同的陀螺仪具有相同的比例因子。
This paper reports the principle of an micro-machined gyroscope (angular rate sensor), whose output signal is fuse both roll rate and yaw rate two information. The output sine wave frequency is the rotating carrier roll rate, which is easily detected, but the amplitude depends on the roll rate and yaw rate. Otherwise, fabrication defects are always inevitably present, which gives rise to the scale factor of different gyroscope can not be identical. In order to solve these problems, a simple method is presented. The results show that the relationship between output signals and yaw rate is linearity and thus reduce the effect of the roll rate variety on the output signal. Further, different gyroscopes have the same scale factor.
