Fuzzy Sliding Mode Control Applied To A Doubly Fed Induction Generator For Wind Turbines, Sid Ahmed El Mehdi Ardjoun, Mohamed Abid
Fuzzy Sliding Mode Control Applied To A Doubly Fed Induction Generator For Wind Turbines, Sid Ahmed El Mehdi Ardjoun, Mohamed Abid
Turkish Journal of Electrical Engineering and Computer Sciences
In this paper an indirect vector control using fuzzy sliding mode control is proposed for a double-fed induction generator (DFIG), applied for a wind energy conversion system in variable speed. The objective is to independently control the active and reactive power generated by the DFIG, which is decoupled by the orientation of the flux. The sliding mode control finds its strongest justification for the problem concerning the use of a robust nonlinear control law for the model uncertainties. As far as the fuzzy mode control is concerned, it aims at reducing the chattering effect. The obtained results show the increasing …

The aim of this work is to developing sliding mode control of active and reactive stator powers produced by a wind energy conversion system (WECS), based on doubly fed induction generator (DFIG). A flux estimation model and rotor current sensor are no longer required. The controller is developed from the DFIG nonlinear-coupled model. Moreover, the global stability and the DFIG states' boundedness when our low-cost sliding mode control is applied are established analytically. It is revealed that the $(dq)$ components of the rotor flux remain near their nominal values. Our approach is validated via simulation in the case of a …
