This paper proposes a new method for obtaining the maximum power output of a doubly fed induction generator (DFIG) wind turbine. This scheme does not require the precise parameters of the wind turbine or any information about the wind speed or wind sensor. The maximum power point tracking (MPPT) ability of the proposed method is theoretically proven under some certain assumptions. To obtain the required control performance, several control parameters may be adopted. Particularly, the control method is constructed on the basis of the Lyapunov function. The quality of the proposed method is verified by the numerical simulation of a 1.5-MW DFIG wind turbine. The simulation results show that the wind turbine implemented with the proposed method can track the optimal operation point. Furthermore, the energy output of the DFIG wind turbine using the proposed method is higher compared to conventional methods under the same conditions. © 2016 Elsevier Ltd
