ABSTRACT:
A control device is provided which is adapted for controlling at least one operational parameter of a wind turbine including a machine nacelle and a rotor having at least one rotor blade. The control device includes an input adapted for inputting a signal which is indicative of environmental data of the wind turbine, an evaluation unit adapted for generating at least one control signal on the basis of currently acquired environmental data and on the basis of previously acquired environmental data, and an output adapted to output the control signal adapted for adjusting the at least one operational parameter of the wind turbine.
