Abstract :
We present an adaptive controller for tuning the natural frequency of the drive axis of a vibrational gyroscope. This is an attractive alternative to a phase-locked loop, since it introduces feedback, which can reduce the effects of imprecise fabrication. We also operate the gyroscope at a fixed frequency, chosen by the designer, which can simplify signal processing.
