A controller for maximum wind energy capture of wind power system according to the theory of auto disturbance rejection controller has been presented. The uncertainties in the torque of turbine and friction are both considered as the unknown disturbance to the system. The expending state observer can evaluate the unknown disturbance. With the nonlinear state error feedback control law, the disturbance can be compensated. The control law is only related with the reference and the output. So the control is simplified with fewer variables detected. The maximum energy capture is achieved through the design of tracking differentiator. The feasibility, adaptability and robustness of the control is testified by this result.
