Titre : Low-speed and standstill operation of a sensorless direct torque and flux controlled IPM synchronous motor drive Type de document : texte imprimé Auteurs : Foo, G., Auteur ; Sayeef, S., Auteur ; Rahman, M.F., Auteur Année de publication : 2010 Article en page(s) : pp. 25 - 33 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : PI control closed loop systems machine vector observers permanent magnet motors synchronous motor drives torque control Résumé : This paper investigates a sensorless direct torque and flux control scheme for interior permanent magnet synchronous motor drives at low speeds, including standstill. Closed-loop control of both torque and stator flux linkage are achieved by using two proportional-integral controllers. The reference voltage vectors are generated by a space vector modulation unit. A high-frequency signal injection technique is adopted at low speeds to obtain the rotor position information. A hybrid current-voltage model flux observer with a smooth handover algorithm estimates the stator flux linkage over the whole speed range. Experimental results confirm the effectiveness of the proposed method. En ligne : http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=5409657&sortType%3Das [...]
