This paper introduces a utility algorithm to reduce the permanent frequency mismatch of the primary wineglass modes in a disk resonator gyroscope via stiffness perturbation. In this algorithm, each tuning electrode is regarded as two rows of radial springs with negative stiffness. On the basis of the tuning model for a ring with radial springs, we can obtain the functional relation between equivalent...
This paper reports a novel honeycomb-like disk resonator for gyroscopic application. Compared with the state of the art nested-rings disk resonator, the honeycomb-like disk resonator can provide more than two-fold higher immunity to the fabrication error, which means that structure imperfection could cause less relative frequency error. The honeycomb-like disk resonator also shows much higher resonant...
