Abstract
Whirl in a drilling system may be identified and mitigated by monitoring signals from a plurality of sensors positioned at various axial locations along a drill string of the drilling system, determining a respective frequency component and a respective amplitude component for each of the signals, identifying whirl in the drill string based on at least two of the respective frequency components and their respective amplitude components, and mitigating the whirl by introducing noise into the drilling system to reduce or eliminate the whirl without removing the drill string from a bottom of a borehole and without terminating all rotation of the drill string.
