Tubes à rayons X Résumé : This paper considers joint problems of control and communication in wireless sensor and actuator networks (WSANs) for building-environment control systems. In traditional control systems, centralized control (CC) and distributed control (DC) are two major approaches. However, little work has been done in comparing the two approaches in joint problems of control and communication, particularly in WSANs serving as components of control loops. In this paper, we develop a CC scheme in which control decisions are made based on global information and a DC scheme which enables distributed actuators to make control decisions locally. We also develop methods that enable wireless communications among system devices compatible with the control strategies, and propose a method for reducing packet-loss rate. We compare the two schemes using simulations in many aspects. Simulation results show that the DC can achieve a comparable control performance of the CC, while the DC is more robust against packet loss and has lower computational complexity than the CC. Furthermore, the DC has shorter actuation latency than the CC under certain conditions.

Distributed collaborative control for industrial automation with wireless sensor and actuator networks / Jiming, Chen in IEEE transactions on industrial electronics, Vol. 57 N° 12 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 12 (Décembre 2010) . - pp. 4219 - 4230 Titre : Distributed collaborative control for industrial automation with wireless sensor and actuator networks Type de document : texte imprimé Auteurs : Jiming, Chen, Auteur ; Xianghui, Cao, Auteur ; Peng, Cheng, Auteur Année de publication : 2011 Article en page(s) : pp. 4219 - 4230 Note générale : Génie électrique Langues : Anglais (eng) Mots-clés : Distributed  collaborative  control  (DCC)  Distributed  estimation  Industrial  automation  Wireless  sensor  and  actuator  networks  (WSANs) Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : Wireless sensor and actuator networks (WSANs) bring many benefits to industrial automation systems. When a control system is integrated by a WSAN, and particularly if the network scale is large, distributed communication and control methods are quite necessary. However, unreliable wireless and multihop communications among sensors and actuators cause challenges in designing such systems. This paper proposes and evaluates a new distributed estimation and collaborative control scheme for industrial control systems with WSANs. Extensive results show that the proposed method effectively achieves control objectives and maintains robust against inaccurate system parameters. We also discuss how to dynamically extend the scale of a WSAN with only local adjustments of sensors and actuators.
