Robust Sensor-less Backstepping of DFIG based on SMO in System of Wind Turbine

Abstract

This study presents the control (sensor-less Backstepping Control) of DFIG (doubly fed induction generator) associated with the system of wind turbine, the sliding mode observer (SMO) is used the error between the estimated and measured voltages/currents to produce surfaces of the sliding mode, the observed position/speed values are pushed to converge to the sliding surfaces. Results of simulation confirmed the performance and robustness of the sensor-less backstepping control of a DFIG associated with SMO.
