A wind turbine system is presented. The wind turbine system includes a wind turbine comprising a plurality of blades and a tower, and a processing subsystem configured to shut down the wind turbine by non-linearly pitching out the plurality of blades in the wind turbine towards a feather position at a pitch rate determined based upon a tower-fore-aft velocity of a top-portion of the tower during oscillations of the tower.
