Delay-dependent stabilization of discrete-time systems with time-varying delay via switching technique / Zhang Hui in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 134 N° 4 (Juillet 2012) 

Public ISBD [article]  in Transactions of the ASME . Journal of dynamic systems, measurement, and control > Vol. 134 N° 4 (Juillet 2012) . - 05 p. Titre : Delay-dependent stabilization of discrete-time systems with time-varying delay via switching technique Type de document : texte imprimé Auteurs : Zhang Hui, Auteur ; Shi, Yang, Auteur Année de publication : 2012 Article en page(s) : 05 p. Note générale : Dynamic systems Langues : Anglais (eng) Mots-clés : Discrete-time  systems  Randomly  time-varying  delays  Occurence  probability  Switching  controllers  Exponential  meansquare  stability  Linear  matrix  inequality Index. décimale : 629.8 Résumé : In this paper, we investigate the stabilization problem of time-delay discrete-time systems with occurrence probabilities for time delays. Using an augmenting technique, we convert random time-delay discrete-time systems to delay-free systems with stochastic variables. We propose to design a sequence of delay-dependent controllers. The implemented controller is chosen according to the measured time delay at each sampling instant. When the delay is randomly time-varying, the implemented controller is switched in a designed controller set. An example is provided to illustrate the effectiveness of the stability condition and another example is offered to show the applicability of the proposed design algorithm.

Modified generalized predictive control of networked systems with application to a hydraulic position control system / Yu, Bo in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 133 N° 3 (Mai 2011) 

Public ISBD [article]  in Transactions of the ASME . Journal of dynamic systems, measurement, and control > Vol. 133 N° 3 (Mai 2011) . - 09 p. Titre : Modified generalized predictive control of networked systems with application to a hydraulic position control system Type de document : texte imprimé Auteurs : Yu, Bo, Auteur ; Shi, Yang, Auteur ; Huang, Ji, Auteur Année de publication : 2011 Article en page(s) : 09 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : Netorked  control  systems  (NCSs)  Generalized  predictive  control  (GPC)  Time  delays  Packet  droputs  Markov  chains  Stochastic  stability Index. décimale : 629.8 Résumé : This paper is concerned with the design of networked control systems using the modified generalized predictive control (M-GPC) method. Both sensor-to-controller (S-C) and controller-to-actuator (C-A) network-induced delays are modeled by two Markov chains. M-GPC uses the available output and prediction control information at the controller node to obtain the future control sequences. Different from the conventional generalized predictive control in which only the first element in control sequences is used, M-GPC employs the whole control sequences to compensate for the time delays in S-C and C-A links. The closed-loop system is further formulated as a special jump linear system. The sufficient and necessary condition to guarantee the stochastic stability is derived. Simulation studies and experimental tests for an experimental hydraulic position control system are presented to verify the effectiveness of the proposed method.
