Abstract：Control technology of wind turbines with trailing edge flaps (TEF) has great potential in large wind turbine system. The aerodynamic model of the wind turbines with trailing edge flaps is proposed firstly based on the modified blade element momentum method (BEM) in this paper. Then, the nonlinear controller for the nonlinear model of wind turbines with TEF is designed using backstepping control method, the state variables and control signal are globally bounded and the output power of the wind turbine system can converge to a small region around the rated power. The information of wind speed is not used in the design of nonlinear controller, so the control strategy reduces the difficulty of the implementation on the engineering domain. Finally, simulation of control system are carried out under 12 m/s～15 m/s step wind, wind disturbance based on the four-components wind model, external disturbance and 10%wind turbine rotary inertia uncertain-ty. The simulation results show that the proposed controller is capable of stabilizing the output power of the wind turbine effectively and has strong robustness.
