BPN779: Rate Integrating Gyroscope (RIG)

Abstract The goal of the project is to implement a rate-integrating gyroscope. Rate integrating gyroscope (RIG) measures the change in angle directly unlike rate gyroscope (RG) in which angular rate is measured. The benefit of measuring angle directly is elimination of integrating the angular rate output to obtain 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. Control algorithms should be developed to eliminate these errors.
