Presents
Modal Tuning and Noise Analysis of MEMS Vibratory
Gyros

Mechanical and Aerospace Engineering - UCLA
Friday, April 9, 2010, 3:00 4:00pm WEBB 1100
Abstract:
Vibratory gyros rely on the Coriolis-coupling of two lightly damped modes when the sensor's equations
of motion are written in case-fixed coordinates. The highest sensor signal-to-noise ratio is achieved
when the two modes are degenerate, i.e. the modal frequencies are equal. The first portion of the
seminar will discuss various systematic tuning methods using stiffness and mass matrix perturbation
to achieve, for all intents and purposes, modal degeneracy. The remainder of the talk will discuss the
noise analysis of the closed-loop mode of operation and dispel the myth that closing the loop leads to
inferior performance of the integrated rate when compared to the open-loop case.
