Dealing with irregular data in soft sensors / Khatibisepehr Shima ; Biao Huang in Industrial & engineering chemistry research, Vol. 47 n°22 (Novembre 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°22 (Novembre 2008) . - p. 8713–8723 Titre : Dealing with irregular data in soft sensors : bayesian method and comparative study Type de document : texte imprimé Auteurs : Khatibisepehr Shima, Auteur ; Biao Huang, Auteur Année de publication : 2008 Article en page(s) : p. 8713–8723 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Irregular  Data Résumé : The main challenge in developing soft sensors in process industry is the existence of irregularity of data, such as measurement noises, outliers, and missing data. This paper is concerned with a comparative study among various data-driven soft sensor algorithms and the Bayesian methods. The algorithms to be considered for a comparative study in this paper include ordinary least-squares, robust regression, error-in-variable methods, partial least-squares, and the Bayesian inference algorithms. Methods for handling irregular data are reviewed. An iterative Bayesian algorithm for handling measurement noise and outliers is proposed. Performance of the Bayesian methods is compared with other existing methods through simulations, a pilot-scale experiment, and an industrial application.

Steady-state analysis of a dual-winding reluctance generator with a multiple-barrier rotor / Fukami, T. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 492 - 498 Titre : Steady-state analysis of a dual-winding reluctance generator with a multiple-barrier rotor Type de document : texte imprimé Auteurs : Fukami, T., Auteur ; Momiyama, M., Auteur ; Khatibisepehr Shima, Auteur Année de publication : 2008 Article en page(s) : pp. 492 - 498 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Magnetic  leakage;  reluctance  generators Résumé : This paper presents the modeling and steady-state performance of a novel dual-winding reluctance generator (DWRG) that uses a multiple-barrier (MB) rotor. A simple mathematical model was developed, and the effects of external parameters (speed, field current, and load) on the steady-state performance were analyzed. Experimental results conducted on a prototype machine were also provided to justify the theoretical approach and performance calculations. The developed model takes into account the magnetic saturation and core loss and enables a quantitative prediction of load characteristics from the no-load test data.
