Public ISBD [article]  inIEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 1015 - 1024 Titre : Development of a nonlinear and model-based online loss minimization control of an IM drive Type de document : texte imprimé Auteurs : Uddin, M.N., Auteur ; Sang Woo Nam, Auteur Année de publication : 2009 Article en page(s) : pp. 1015 - 1024 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Adaptive control  digital signal processing chips  induction motor drives  invertors  machine theory  minimisation  nonlinear control systems Résumé : Among the numerous loss minimization algorithms, a loss-model-based approach offers a fast response without torque pulsations. However, it requires the accurate loss model and the knowledge of the motor parameters. Therefore, a technical difficulty in deriving the loss-model-based controller (LMC) lies in the complexity of the full loss model and the online motor parameter adaptation. In an effort to overcome the drawbacks of LMC, this paper presents a new strategy for inverter-fed induction motors drives aiming for both high efficiency and high dynamic performance. A new LMC incorporating the effect of the leakage inductance and an adaptive-backstepping-based nonlinear controller are designed and combined with each other. Thus, online parameter adaptation of LMC can be obtained with no extra effort. The proposed control scheme is implemented in real time using digital signal processor board DS 1104. The simulation and experimental results demonstrate the effectiveness of the proposed scheme.
