Robust Sensor-less SMC under Variable-Speed Wind Turbine Systems of DFIG based on FKE

This paper study the robust nonlinear sensor-less sliding mode control (SMC) of the wind turbine chain associated with doubly fed induction generator (DFIG), the energy transfer between the grid and stator of DFIG, a reversible signal converter is used to apply to the rotor. The extended Kalman filter (EKF) is used the error between the estimated and measured voltages/currents to the production of estimation speed and position values. The simulations of results confirmed the performance of the control (SMC) of a DFIG sensor-less speed based on extended Kalman filter and validate a good dynamic performance.
