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

Control of wind turbine blade lift regulating means

The invention relates to a wind turbine blade with at least one control surface and an actuator inside the main body of the wind turbine blade for moving the control surface, wherein the actuator comprises a fluidic muscle, a controller and a pump, and wherein the fluidic muscle is adapted to change in length and width when the pressure of the fluid within the fluidic muscle is varied.
