Study of variable-pitch wind turbine based on fuzzy control

First, the analysis of developing status of wind turbine control strategy has been made; Second, some mathematical models about aerodynamic parts are established according to the principle of the wind power generating units various parts. At the same time, some sub-modules of the wind turbine are established in MATLAB. At last, the control strategy based on Fuzzy controller is design and simulated by MATLAB/simulink. Both in the low wind speed and high speed the power output of the generator can quickly reached a stability (about 4s), which improve the control system respondent time.
