Abstract
In one aspect, a method for controlling the amplitude modulation of noise generated by a wind turbine is disclosed. The method may generally include determining an angle of attack of a rotor blade of a wind turbine and maintaining the angle of attack at a substantially constant value during rotation of the rotor blade in order to reduce the amplitude modulation of the noise generated by the wind turbine.
