The present disclosure is directed to a system 100 and method 200 for reducing vibrations of a tower 12 (e.g. a tubular steep tower or a lattice tower structure) of a wind turbine 10. The method includes continuously determining a torsional movement of the tower 12 based at least in part on measurements obtained from one or more sensors. Another step includes continuously determining, via a controller 25, a control command for one or more pitch drive mechanisms 38 of the wind turbine 10 based on the torsional movement. Thus, the method also includes operating the one or more pitch drive mechanisms 38 based on the control command so as to dampen the torsional movement of the tower 12. |
