As the wind speed is random and uncertain

and the wind power system is nonlinear and strong coupling

only a specific set of parameters in the traditional PID control can hardly achieve the real-time speed tracking for wind turbine at different wind speeds.In the variable speed constant frequency(VSCF)doubly-fed wind power system

the characteristics of wind turbine are nonlinear and the moment of inertia is great.According to the maximum wind energy tracking features

the fuzzy PID control strategy for wind turbine speed tracking below the rated wind speed was presented

so the wind turbine can operate at the best torque.Control effect of the fuzzy PID was verified through the simulation.The results show that it can achieve good control effect in the speed control of wind turbine nonlinear system.
