Abstract
A vibration damping technique for a wind turbine system is described. The wind turbine system includes a vibration damper, which provides a variable signal to control torque produced by a generator of the wind turbine system. The variable signal is based on generator speed and has a first local peak value based on a resonant frequency of tower side-to-side oscillation.
