Abstract
A control method and a wind turbine for adaptively adjusting the operation of the wind turbine to maintain maximum power production during degraded conditions. The control system has an estimator module that determines a scaling factor based on the current set of control signals and at least the current set of measurement of the operating parameters. The scaling factor is transmitted to a control module which scales at least one aerodynamic property of the rotor based on this scaling factor. The control module further determines the ideal settings for the control signals based on the scaled aerodynamic properties. The present control method scales the aerodynamic properties to provide a better representation of the actual degraded aerodynamic properties.
