Abstract
The invention involves a wind turbine comprising at least one blade (5) in turn comprising a blade body (501), lift-regulating means (502) adapted for movement in relation to the blade body (501) so as to regulate the lift of the blade, and load sensing means (5022, 506) for determining a load acting on the lift-regulating means (502), the wind turbine further comprising an actuation control unit (6) adapted to control the movement of the lift-regulating means (502) based on output from the load sensing means (5022, 506). In addition to output from the load sensing means (5022, 506), the actuation control unit (6) is adapted to control the movement of the lift-regulating means (502) based on the movement of the lift-regulating means (502).
