Zusammenfassung:	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). L'invention porte sur une turbine éolienne qui comprend au moins une pale (5) comprenant à son tour un corps de pale (501), un moyen de régulation de levage (502) apte à effectuer un mouvement par rapport au corps de pale (501) de façon à réguler le soulèvement de la pale, et des moyens de détection de charge (5022, 506) permettant de déterminer une charge agissant sur le moyen de régulation de levage (502), la turbine éolienne comprenant en outre une unité de commande d'actionnement (6) apte à commander le déplacement du moyen de régulation de levage (502) en fonction d'une sortie provenant des moyens de détection de charge (5022, 506). En plus de la sortie provenant des moyens de détection de charge (5022, 506), l'unité de commande d'actionnement (6) est apte à commander le déplacement des moyens de régulation de levage (502) en fonction du déplacement des moyens de régulation de levage (502).
