Aerodynamic load over the rotating wind turbine blade is modeled by Beddies-Leishman model. The flutter issue of the blade caused by unsteady loads has been addressed by the design of Adaptive Controller. The robustness and effectiveness of designed controller are shown by good performance in suppressing the blade vibration and reaching the desired pitch angle required by wind turbine operation for open-loop and closed-loop simulation tests. The ability of Microtabs in active flow control is revealed by the response of gurney flap within 5% of chord length and reasonable rate. Experiments are implemented to demonstrate the superior ability of Adaptive Controller in flutter suppression for a wide range of aerodynamic loads.
