The invention relates to a control device for a wind power converter with adjustable rotor blades. The blade tips are pivotally mounted and under the effect of differing centrifugal forces assume different setting angles in relation to the rotor plane. The rotor shaft carries a displaceable synchronising device which acts against a force. The blade tip is likewise influenced by a force in its direction away from the rotor hub and the two forces are directed in opposition. The adjustment can be influenced by a control element regardless of the centrifugal forces. The blade tip is turned in a guide slot by means of a guide bolt in a plane which is attuned to the differing centrifugal forces. <IMAGE>
