A differential state-space approach to simultaneous emulation of uncertainties and disturbances in voltage-controlled brushless motors / Kuperman, Alon in IEEE transactions on industrial electronics, Vol. 57 N° 2 (Fevrier 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 2 (Fevrier 2010) . - pp. 727 - 734 Titre : A differential state-space approach to simultaneous emulation of uncertainties and disturbances in voltage-controlled brushless motors Type de document : texte imprimé Auteurs : Kuperman, Alon, Auteur ; Horen, Yoram, Auteur ; Tapuchi, Saad, Auteur Article en page(s) : pp. 727 - 734 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Brushless  motors  Digital  signal  processor  (DSP)  Hardware-in-the-loop  (HIL)  Simulation Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A method that allows emulation of parameter uncertainties and external disturbances without any mechanical and electrical parts supplementary to the electric drive is proposed. The emulating signal reflecting the desired changes is created in software and added to the nominal controller output, forcing the unperturbed motor output to resemble the output of a motor with actual uncertainties and disturbances. The proposed method allows simultaneous emulation of any combination of parameter variations and unpredicted disturbances. The method can be related to a class of advanced hardware-in-the-loop simulations, where the nominal hardware is present in the test bed in addition to the controller. The technique can be used to thoroughly test the performance of advanced control algorithms before mass production or for didactic purposes in an educational laboratory using motion control kits found on the market. Simulation and experimental results are reported to prove the feasibility of the proposed approach.

Uncertainty and disturbance estimator–based control for uncertain LTI-SISO systems with state delays / Stobart, R. K. in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 133 N° 2 (Mars 2011) 

Public ISBD [article]  in Transactions of the ASME . Journal of dynamic systems, measurement, and control > Vol. 133 N° 2 (Mars 2011) . - 06 p. Titre : Uncertainty and disturbance estimator–based control for uncertain LTI-SISO systems with state delays Type de document : texte imprimé Auteurs : Stobart, R. K., Auteur ; Kuperman, Alon, Auteur ; Qing-Chang, Zhong, Auteur Année de publication : 2011 Article en page(s) : 06 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : uncertainty  and  disturbance  estimator  (UDE)  Time-delay  systems  Uncertainty  Robust  control  Time-delay  control Index. décimale : 629.8 Résumé : In this paper, a robust control strategy based on the uncertainty and disturbance estimator (UDE) is proposed for uncertain Linear Time Invariant-Single Input Single Output (LTI-SISO) systems with state delays. The knowledge of the bounds of uncertainties and disturbances is not needed during the design process although it is required for the stability analysis. Both the cases with known and unknown delays are considered. In the case of unknown delays, the terms involving the delays are treated as additional disturbances to the system. The robust stability of the closed-loop system is analyzed in detail, and a stability condition is proposed. Simulations are given to demonstrate the excellent tracking and disturbance rejection capabilities of the UDE-based control strategy.
