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.

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.

Machinerie Résumé : The design problem of networked control systems (NCS) with constant and random network delay in the forward and feedback channels, respectively, is considered in this paper. A novel networked predictive control (NPC) scheme is proposed to overcome the effects of network delay and data dropout. Stability criteria of closed-loop NPC systems are presented. The necessary and sufficient conditions for the stability of closed-loop NCS with constant time delay are given. Furthermore, it is shown that a closed-loop NPC system with bounded random network delay is stable if its corresponding switched system is stable. Both simulation study and practical experiments show the effectiveness of the control scheme.

On propose un arrangement prédictif géré en réseau de la commande de roman (NPC) pour surmonter les effets du réseau retardent et du renvoi de données. Des critères de stabilité des systèmes en circuit fermé de NPC sont présentés. Les conditions nécessaires et suffisantes pour la stabilité de NCS en circuit fermé avec du temps constant retardent sont données. En outre, on lui montre qu'un système en circuit fermé de NPC avec le réseau aléatoire lié retardent est stable si son système commuté correspondant est stable.

Titre : Packet-based deadband control for internet-based networked control systems Type de document : texte imprimé Auteurs : Yun-Bo Zhao, Auteur ; Liu, Guo-Ping, Auteur ; Rees, David, Auteur Année de publication : 2011 Article en page(s) : pp. 1057-1067 Note générale : Génie Aérospatial Langues : Anglais (eng) Mots-clés : Deadband control Internet-based test rig Networked control systems Packet-baded control Stability Index. décimale : 629.1 Résumé : A packet-based deadband control approach is proposed for networked control systems (NCSs). Compared with previously reported packet-based control approaches to NCSs, the approach proposed in this paper takes full advantage of the packet-based data transmission in NCSs, and thus considerably reduces the use of the communication resources in NCSs whilst maintaining the system performance at a satisfactory level. A stabilized controller design method is obtained using time delay switched system theory, which has not been achieved in previously reported packet-based control approaches. The proposed deadband control strategy and the stabilized controller design method are verified using a numerical example as well as practical experiments based on an Internet-based test rig for NCSs.
