A speed-adaptive reduced-order observer for sensorless vector control of doubly fed induction generator-based variable-speed wind turbines / Sheng Yang in IEEE transactions on energy conversion, Vol. 25, N° 3 (Septembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 3 (Septembre 2010) . - pp. 891 - 900 Titre : A speed-adaptive reduced-order observer for sensorless vector control of doubly fed induction generator-based variable-speed wind turbines Type de document : texte imprimé Auteurs : Sheng Yang, Auteur ; Ajjarapu, V., Auteur Année de publication : 2011 Article en page(s) : pp. 891 - 900 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Angular  velocity  control;  asynchronous  generators;  machine  vector  control;  observers;  sensitivity  analysis;  sensorless  machine  control;  wind  turbines Résumé : In this paper, a speed-adaptive reduced-order observer for sensorless vector control of doubly fed induction generators (DFIGs) is proposed. The observer is a simulation of the rotor current dynamic model with feedback of the estimation error and a speed-adaptation loop. Feedback and adaptation gains are designed based on the closed-loop observer model. A parameter sensitivity analysis reveals that this observer is robust against machine parameter variations in the normal operating regions. Simulation results demonstrate desired steady-state and dynamic performance of this sensorless control approach for DFIG-based variable-speed wind turbines.
