摘要

本文报道了一种利用独立控制的连续波和连续波模式振荡实现全角陀螺仪虚旋转的方法。该方法不需要任何额外的虚旋转机制，而只改变两个锁相环的目标相位值。将约0.163 Hz的虚拟旋转成功应用于WAG，解决了锁角现象。观察到的偏置不稳定性小至1.1°/hr。

Virtually rotated MEMS whole angle gyroscope using independently controlled CW/CCW oscillations

This paper reports a method to apply virtual rotation to a whole angle gyroscope (WAG) using independently controlled CW and CCW mode oscillations. The method does not require any additional mechanisms for the virtual rotation, but only changes the target phase values of two phase locked loops (PLLs). The virtual rotation at about 0.163 Hz was successfully applied to the WAG, and the angle locking phenomenon could be resolved. The bias instability as small as 1.1°/hr was observed.
