Micro Rate-Integrating Gyroscope [BPN603]
The goal of this project is to realize a micro rate-integrating gyroscope that
produces an output signal proportional to rotation angle rather than rotation rate. This
device would eliminate the need of integrating the gyroscope's rate output to obtain the
angle. Gyroscope resonators have at least two resonant modes that can be coupled by Coriolis
force. Difference in damping coefficients and stiffness of the resonant modes of the MEMS
resonator known as anisodamping and anisoelasticity are main sources of error in RIG. So
realizing a micro rate-integrating gyroscope can be achieved by having highly symmetrical
gyroscopes with extremely close frequency matching (delta f < 1 Hz) and high time constant
(high quality factor). Control algorithms should be developed to eliminate the residual
anisodamping and anisoelasticity errors.
