Beschreibung
Zusammenfassung:	A control method for controlling a wind turbine comprising a rotor hub with a shaft and at least two blades, and a nacelle rotatably coupled to the tower through a yaw system, is provided. The control method includes steps for measuring a first periodic variable relating to the nacelle, measuring a second periodic variable relating to the shaft, estimating a yaw moment based on the data obtained from the first variable, processing the signal corresponding to the estimated yaw moment to extract a 1P frequency component from the signal, calibrating the yaw moment estimated, and adjusting the pitch angle of the corresponding blade to counteract the 1P frequency component of the estimated signal of the yaw moment after calibration, in turn comparing it with the signal of the second variable, is also provided.
