Provided is a control device configured to control a wind turbine, the wind turbine including a rotor being rotatable about a rotational axis, wherein the rotor has at least one blade, the blade including at least one add-on member which is actuated by a corresponding trim actuator to alter aerodynamic properties of the blade and a pitch actuator to alter a pitch angle of the blade. The control device is configured to determine an idling mode or a self-sustaining mode of the wind turbine; to control the pitch actuator to set a predetermined pitch angle of the blade, if the idling mode or the self-sustaining mode is determined; and to cause a target rotational speed of the rotor by variably controlling the trim actuator of the blade, if the idling mode or the self-sustaining mode is determined.
