Guaranteed cost control for networked control systems based on an improved predictive control method / Rui, Wang in IEEE Transactions on control systems technology, Vol. 18 N° 5 (Septembre 2010) 

Public ISBD [article]  in IEEE Transactions on control systems technology > Vol. 18 N° 5 (Septembre 2010) . - pp. 1226-1232 Titre : Guaranteed cost control for networked control systems based on an improved predictive control method Type de document : texte imprimé Auteurs : Rui, Wang, Auteur ; Liu, Guo-Ping, Auteur ; Wang, Wei, Auteur Année de publication : 2011 Article en page(s) : pp. 1226-1232 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Guaranteed  cost  control  Linear  matrix  inequalities  (LMIs)  Networked  control  system  (NCS)  Predictive  control  Switched  systems Index. décimale : 629.1 Résumé : This brief deals with the problem of guaranteed cost control for a class of uncertain networked control systems with time-varying delay. An improved predictive controller design strategy is proposed to compensate for the delay and data dropout in both the forward and backward channels to achieve the desired control performance. The varying controller gains which are designed to vary with delays can lead to less conservative results. Meanwhile, an algorithm involving a convex optimization problem is presented to achieve a suboptimal guaranteed cost. Furthermore, a numerical simulation and a practical experiment are given to illustrate the effectiveness of the proposed method.

H [infinity] control for networked predictive control systems based on the switched Lyapunov function method / Rui, Wang in IEEE transactions on industrial electronics, Vol. 57 N° 10 (Octobre 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 10 (Octobre 2010) . - pp. 3565 - 3571 Titre : H [infinity] control for networked predictive control systems based on the switched Lyapunov function method Type de document : texte imprimé Auteurs : Rui, Wang, Auteur ; Liu, Guo-Ping, Auteur ; Wang, Wei, Auteur Année de publication : 2011 Article en page(s) : pp. 3565 - 3571 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : H[infinity]  control  Networked  control  systems  (NCSs)  Predictive  control  Switched  Lyapunov  function  Switched  systems Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper investigates the problem of H∞ control for a class of networked control systems (NCSs) with time-varying delay in both forward and backward channels. Combined with the switched Lyapunov function technique, an improved predictive controller design strategy is proposed to compensate for the delay and data dropout to achieve the desired control performance. Based on these methods, the controllers can be designed to guarantee that the closed-loop system is asymptotically stable with an H∞-norm bound in terms of nonlinear matrix inequalities. An iterative algorithm is presented to solve these nonlinear matrix inequalities to obtain a suboptimal minimum disturbance attenuation level. Numerical simulations and a practical experiment are given to illustrate the effectiveness of the proposed method.

Prediction of the upper flammability limits of organic compounds from molecular structures / Yong Pan in Industrial & engineering chemistry research, Vol. 48 N° 10 (Mai 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 10 (Mai 2009) . - pp. 5064–5069 Titre : Prediction of the upper flammability limits of organic compounds from molecular structures Type de document : texte imprimé Auteurs : Yong Pan, Auteur ; Juncheng Jiang, Auteur ; Rui, Wang, Auteur Année de publication : 2009 Article en page(s) : pp. 5064–5069 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Organic  compounds  Upper  flammability  limits  Genetic  algorithm  Multiple  linear  regression Résumé : A quantitative structure−property relationship (QSPR) study is performed to develop mathematical models for prediction of the upper flammability limits (UFL) of organic compounds from their molecular structures. The structural features of the compounds are numerically represented by various kinds of calculated molecular descriptors such as topological, charge, and geometric descriptors. The genetic algorithm combined with multiple linear regression (GA-MLR) is used to select an optimal subset of descriptors that have significant contribution to the overall UFL property from the large pool of calculated descriptors. The best resulted model is a four-variable multilinear model with a defined applicability range. The average absolute error and root-mean-square error obtained for the external test set are 1.75 vol % and 2.77, respectively. The proposed model can be used to predict the UFL of organic compounds with only four preselected theoretical descriptors which can be directly calculated from molecular structure alone.
