Frequency-shaped sliding mode control using output sampled measurements / Mehta, A. J. in IEEE transactions on industrial electronics, Vol. 56 N°1 (Janvier 2009) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 56 N°1 (Janvier 2009) . - pp. 28 - 35 Titre : Frequency-shaped sliding mode control using output sampled measurements Type de document : texte imprimé Auteurs : Mehta, A. J., Auteur ; Bandyopadhyay, B., Auteur Année de publication : 2009 Article en page(s) : pp. 28 - 35 Note générale : elecronics Langues : Anglais (eng) Mots-clés : frequency  control;  variable  structure  systems Résumé : In this paper, a method is presented for frequency-shaped sliding mode control using output feedback. A compensator is introduced in the sliding surface to attenuate the certain frequency component of the sliding mode dynamics. The output is measured at a faster rate than the control input to estimate the states of the system. The proposed output feedback frequency-shaped sliding mode controller is designed for the vibration suppression of intelligent structure. The simulation and experimental results show the efficacy of the method.

Reduced-order observer design for servo system using duality to discrete-time sliding-surface design / Mehta, A. J. in IEEE transactions on industrial electronics, Vol. 57 N° 11 (Novembre 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 11 (Novembre 2010) . - pp. 3793 - 3800 Titre : Reduced-order observer design for servo system using duality to discrete-time sliding-surface design Type de document : texte imprimé Auteurs : Mehta, A. J., Auteur ; Bandyopadhyay, B., Auteur ; Inoue, A., Auteur Année de publication : 2011 Article en page(s) : pp. 3793 - 3800 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Duality  between  reduced  order  observer  and  sliding  surface  design  Reduced  order  observer  Servo  system  Variable  structure  systems Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a design method of a discrete-time reduced-order observer using the duality to discrete-time sliding-surface design. First, the duality between the coefficients of the discrete-time reduced-order observer and the sliding-surface design is established, and then, the design method for the observer using the Riccati equation is explained. A discrete-time sliding-mode controller based on the proposed observer is designed and tested on a laboratory-type experimental servo system. The results show the efficacy of the reduced-order observer designed by the duality concept.
