Short summary
This work presents a new fully automated method to correct for pitch misalignment imbalances of wind turbine rotors. The method has minimal requirements, as it only assumes the availability of a sensor of sufficient accuracy and bandwidth to detect the 1P harmonic to the desired precision and the ability to command the pitch setting of each blade independently from the others. Extensive numerical simulations are used to demonstrate the new procedure.
