Abstract

This work presents the development of an extremum seeking controller (ESC) based on periodic perturbation for tracking the resonance frequency in HRG gyros. For controller validation, a simulation model based on gyro motion equations is developed in Simulink environment. The behavior is analyzed for systems with one or two resonance peaks and for time-varying resonance frequencies.
