Abstract
This paper presents a newly developed aero-servo-elastic platform, which was built by improving FAST/Aerodyn codes with the integration of an external deformable trailing edge flap PID controller into the Matlab/Simulink software. Based on the platform, the effect of smart rotor control on aerodynamic load reduction on NREL/Upwind 5 MW reference wind turbine was investigated under various operating wind conditions in accordance with the IEC standard. Results showed that, irrespective of Normal Turbulence Model(NTM) and Extreme Turbulence Model(ETM) cases, aerodynamic load in terms of blade fiapwise root moment and tip deflection were effectively reduced.
