Abstract
A method for generating a blade pitch angle control signal for controlling a blade pitch angle of a rotating rotor blade for damping a rotor blade vibration, in particular an edgewise rotor blade vibration, of the rotating rotor blade is disclosed. The blade pitch angle control signal is generated such that it varies in accordance with a rotor blade vibration motion. A controller and a wind turbine are also disclosed.

A method for generating a blade pitch angle control signal for controlling a blade pitch angle of a rotating rotor blade for damping a edgewise-rotor-blade vibration of the rotating rotor blade, the method comprising:
- generating a blade pitch angle control signal that varies in accordance with a rotating-rotor-blade-vibration motion.
The method according to claim 22, wherein the radially inner portion of the rotor blade comprises a fixing portion via which the rotor blade is connected to a rotor shaft.
A controller for generating a blade pitch angle control signal for controlling a blade pitch angle of a rotating rotor blade for damping a rotor blade vibration, in particular an edgewise rotor blade vibration, of the rotating rotor blade, wherein the controller is adapted to
- generate the blade pitch angle control signal such that it varies in accordance with a rotor blade vibration motion.
