Experimental Considerations on the Piezoelectric Vibratory Gyrosensor Using a Trident Tuning-Fork Resonator

This paper concerns the piezoelectric vibratory gyrosensor using a trident tuning-fork resonator characterized by high stability. In the first part of this paper, the methods of adjusting the resonance frequencies are discussed. Then the investigations to compensate the imbalance in a trident tuning-fork resonator are shown. Moreover, we constructed an experimental gyrosensor based on these results, using differential detection to eliminate the leakage output signals. A miniature piezoelectric vibratory gyrosensor with superior linearity could be achieved.
