PIEZOELECTRIC VIBRATORY RATE SENSOR |
摘要 |
<p>A vibrating rotation rate sensor of the type that includes a generally-planar, H-shaped frame of piezoelectric material such as quartz. A first set of drive electrodes is fixed to a pair of upper tines and a second set of pickoff electrodes is fixed to a pair of lower tines. An array of control electrodes is fixed to the upper tine pair adjacent the cross-piece of the H-shaped frame. The control electrodes permit the application of control signals for nulling coriolisinduced out-of-plane vibration of the upper tines allowing use of a resonant frame.</p> |
