1. A method of automatically controlling a wind turbine, comprising: determining a time-series of measurement values of an aerodynamic flow property of a wind turbine rotor blade; generating a predictive wind field model representing a structure of a wind field acting on the wind turbine rotor blade based on the time-series of measurement values; generating, based on the wind-field model, a control value to produce a desired operational condition of the wind turbine rotor blade; and adjusting the wind turbine rotor blade according to the control value.
