Abstract	In variable pitch control, the wind speed in the axis of the blade is used as the reference wind speed for wind blade synchronous control. In fact, the wind speed is changing with the height. With the increasing of the wind turbine capacity, the difference of the blade wind speed in different spin high degree is gradually increasing, making the loads of the blades tend to gradually increase, which has seriously affected the wind turbine life. This paper implemented the independent variable pitch control based on the traditional variable pitch control and obtained the amended pitch angle on the use of the state feedback control, which plus the collective pitch is the independent pitch. Through the simulation of the wind turbine at the step and the random wind, it follows that the independent variable pitch control of the wind power generation system can reduce the loads of blades and extend the service life of wind turbines, on condition that the output power is kept stable.
