Abstract

This paper studies the primary control problem of a vibrating MEMS gyroscope. A nonlinear robust adaptive control scheme is proposed for the drive axis of a vibrating MEMS gyroscope with parametric uncertainties and exogenous disturbances. By combining the dynamic surface control (DSC) method with H_∞ disturbance attenuation technique, a simpler systematic design procedure is developed. The derived controller can drive the drive axis to resonance, regulate the output amplitude of drive axis to a desired value, and attenuate the generalized disturbances. The features of derived controller are discussed and illustrated by the simulation on close-loop system.
