Zusammenfassung:	Improved wind turbine control methods and systems. The invention relates to a method for the operation of a variable speed wind turbine having pitch and torque control means that include additional steps for providing to the pitch control means in case of a wind gust a pitch angle reference increment D¸ref in the amount needed for avoiding that the aerodynamic torque added by the wind gust exceeds a predetermined limit. The present invention also relates to a wind turbine comprising a control system arranged for performing an additional regulation in case of wind gust
