Abstract :
We propose an adaptive control scheme to tune the natural frequency of a microelectromechanical (MEMS) resonator for a vibrational gyroscope to a desired frequency. This is an attractive alternative to the phase locked loop, since it introduces feedback, which can reduce the effects of imprecise fabrication. In particular, we use adaptive control to set the natural frequency of the drive axis
