Abstract
A method for wind turbine tower damping is disclosed, as well as an associated controller and wind turbine. The method comprises determining, using one or more sensor signals, dynamic state information for a tower of a wind turbine during power production, wherein the dynamic state information comprises a tower frequency. The method further comprises determining at least one control loop gain value using the tower frequency, and generating, using the at least one control loop gain value, one or more control signals for controlling a rotational speed of a rotor of the wind turbine.

A method comprising:
- determining, using one or more sensor signals, dynamic state information for a tower of a wind turbine during power production, wherein determining the dynamic state information comprises:
- determining, using the one or more sensor signals, a velocity and a position of a reference location of the tower;
- and
- determining a tower frequency based on the one or both of the velocity and the position;
- determining, using the tower frequency, a first control loop gain value and a second control loop gain value;
- and
- generating, one or more control signals for controlling a rotational speed of a rotor of the wind turbine by applying the first control loop gain value to the velocity and the second control loop gain value to the position.
A controller for a wind turbine, the controller comprising:
- one or more computer processors;
- and
- a non-transitory memory comprising computer-readable code that, when executed using the one or more computer processors, performs an operation comprising:
- determining, using one or more sensor signals, dynamic state information for a tower of a wind turbine during power production, wherein determining the dynamic state information comprises:
