Abstract
This paper introduces a new approach to self-calibration of
Coriolis-based vibratory gyroscopes that does not require the
use of any additional moving parts or a calibration stage.
Instead, the effect of the Coriolis force on the device is
mimicked by the application of a rotating excitation to the
device drive and sense modes. This calibration method is
based on the theoretical analysis of an equivalent 2‑DOF
mass-spring model, which can be used to describe the behavior
of a variety of MEMS gyroscopes. The method is validated both
by the results of finite-element simulations and by experimental
measurement.
