Abstract
A method of optimizing the power recovered by a wind turbine by reducing the mechanical impact on the structure is disclosed. A first angle of inclination of the blades allowing the recovered power to be optimized is determined. The aerodynamic force produced on the nacelle when the blades are directed with a first angle is determined. A second angle of inclination of the blades allowing obtaining an aerodynamic force setpoint value is then determined by inverting the aerodynamic force model and using a wind velocity measurement, a rotor velocity measurement and the aerodynamic force setpoint value. Finally, the blades are directed to the second angle.
