High-order sliding-mode control of variable-speed wind turbines / Beltran, Brice in IEEE transactions on industrial electronics, Vol. 56 N° 9 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N° 9 (Septembre 2009) . - pp. 3314-3321 Titre : High-order sliding-mode control of variable-speed wind turbines Type de document : texte imprimé Auteurs : Beltran, Brice, Auteur ; Ahmed Ali, Tarek, Auteur ; Benbouzid, Mohamed El Hachemi, Auteur Article en page(s) : pp. 3314-3321 Langues : Anglais (eng) Mots-clés : Commande  de  glissement  Turbine  à  vent  Vitesse  variable Index. décimale : 621 Ingénierie mécanique en général. Technologie nucléaire. Ingénierie électrique. Machinerie Résumé : This paper deals with the power generation control in variable-speed wind turbines. These systems have two operation regions which depend on wind turbine tip speed ratio. A high-order sliding-mode control strategy is then proposed to ensure stability in both operation regions and to impose the ideal feedback control solution in spite of model uncertainties. This control strategy presents attractive features such as robustness to parametric uncertainties of the turbine. The proposed sliding-mode control approach has been validated on a 1.5-MW three-blade wind turbine using the national renewable energy laboratory wind turbine simulator FAST (Fatigue, Aerodynamics, Structures, and Turbulence) code. Validation results show that the proposed control strategy is effective in terms of power regulation. Moreover, the sliding-mode approach is arranged so as to produce no chattering in the generated torque that could lead to increased mechanical stress because of strong torque variations.
