In order to realize the independent variable pitch control and each blade with wind speed varies, the acceleration weight coefficient assigned to control each blade individually. Then, according to the theory of feedforward compensation of knowledge to compensate the whole controlling process. The pitch control mode of permanent magnet direct-drive wind power system is built and simulated by MATLAB/Simulink simulation system. The simulation results show that not only the proposed strategy has such advantages as str
