1. A method of controlling a wind turbine, the wind turbine comprising a plurality of rotor blades, a first controller for controlling an adaptive flow regulating system having a plurality of individually controllable adaptive flow regulating devices arranged on the rotor blades, and a second controller for controlling a pitch regulating system for regulating a pitch angle of each rotor blade, the method comprising:
determining a diagnostic value indicative of an operational efficiency of the adaptive flow regulating system;
determining a first gain value for the first controller and a second gain value for the second controller based on the diagnostic value;
applying the first gain value to control signals for the adaptive flow regulating system generated by the first controller; and
applying the second gain value to control signals for the pitch regulating system generated by the second controller.
