Abstract: Wind energy generated by using wind as a fuel is clean and non-polluting as a result it has become more widespread today. However, the uncertainty in the aerodynamic parameters makes the wind energy to cost more. Many researches have been done to increase the wind turbine efficiency, but they fail to consider this uncertain aerodynamic parameters. In this paper an adaptive control technique, which resembles the existing quadratic controller used by the wind industry for variable speed wind turbines below rated power, is designed to reduce the negative effects of this uncertainty. This adaptive controller uses a simple, highly intuitive extremum seeking scheme designed to seek out the optimal gain for maximizing the turbine’s energy capture. The adaptive controller has been tested and validated using MATLAB simulation
