Public ISBD [article]  inIEEE Transactions on control systems technology > Vol. 18 N° 1 (Janvier 2010) . - pp. 11-21 Titre : Real-time discrete neural block control using sliding modes for electric induction motors Type de document : texte imprimé Auteurs : Alma Y. Alanis, Auteur ; Edgar N. Sanchez, Auteur ; Loukianov, Alexander G., Auteur Année de publication : 2011 Article en page(s) : pp. 11-21 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Discrete time nonlinear systems Electric induction motor Extended Kalman filtering (EKF) learning Neural block control (NBC) Sliding modes Index. décimale : 629.1 Résumé : This paper deals with real-time adaptive tracking for discrete-time induction motors in the presence of bounded disturbances. A high-order neural-network structure is used to identify the plant model, and based on this model, a discrete-time control law is derived, which combines discrete-time block-control and sliding-mode techniques. This paper also includes the respective stability analysis for the whole system with a strategy to avoid adaptive weight zero-crossing. The scheme is implemented in real time using a three-phase induction motor.

Robust trajectory tracking for an electrohydraulic actuator / Loukianov, Alexander G. in IEEE transactions on industrial electronics, Vol. 56 N° 9 (Septembre 2009)  

Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 56 N° 9 (Septembre 2009) . - pp. 3523-3531 Titre : Robust trajectory tracking for an electrohydraulic actuator Type de document : texte imprimé Auteurs : Loukianov, Alexander G., Auteur ; Rivera, Jorge, Auteur ; Orlov, Yuri V., Auteur Article en page(s) : pp. 3523-3531 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : electrohydraulic actuator Robust control H-infinity controls Index. décimale : 621 Ingénierie mécanique en général. Technologie nucléaire. Ingénierie électrique. Machinerie Résumé : Various robust control techniques, such as integral-block, sliding-mode, and H-infinity controls, are combined to design a controller, forcing an electrohydraulic actuator which is driven by a servovalve to track a chaotic reference trajectory. This approach enables one to compensate the inherent nonlinearities of the actuator and reject matched external disturbances and attenuate mismatched external disturbances. The capabilities of the approach are illustrated in a simulation study.
