摘要：
A control method for controlling load reduction for a wind turbine rotor (3) with rotor blades (5, 7, 9) comprising at least one aerodynamic active element responsive to a control signal for modifying its setting is provided. The method comprising the steps of
- detecting the loads acting on the rotor blades (5, 7, 9) in relation to the rotor's azimuth;
- establishing individual control signals for modifying the settings of the aerodynamic active elements of the rotor blades (5, 7, 9) based on a PI-control system (47); and
- providing the aerodynamic active elements with the individual control signals.
Each individual control signal is a complex number containing an amplitude defining the degree of modification of the respective setting and an angle defining the phase of the modification of the respective setting with respect to the rotor's azimuth. The angle of the complex number is corrected by a phase correction factor.
