Abstract: The invention provides a method for determining angular position of a generator shaft of a wind turbine. The method includes receiving a position signal, from an encoder position sensor of the wind turbine, indicative of an angular position of the generator shaft. The method includes determining a compensation signal to compensate for a disturbance signal in the received position signal indicative of an imperfection associated with the encoder position sensor. The method includes modifying the position signal by applying the determined compensation signal to the received position signal to determine angular position.
