Abstract:

Networked sensing and control has attracted significant interest in recent years due to its wide applications. For example, sensor networks, especially wireless sensor networks, have found important applications in environmental monitoring, agriculture, building and industrial automation, machine condition monitoring, intelligent transportation systems, health care, surveillance, and defense. On the other hand, due to the flexibility and significant cost-saving, there has been an increasing trend for control systems to utilize digital communication networks for exchanging information between sensor and controller and/or controller and actuator, as well as between subsystems or systems sharing the same communication networks. Furthermore, networked multiagent systems, where the collective behavior of a system is realized through interactions among dynamically decoupled systems, have also been the focus of many recent research efforts. In networked systems, the network is an important component with constraints and uncertainties, such as the limited bandwidth, random transmission-delays, possible packet-losses, out-of-sequence measurements, etc. The uncertainties and constraints become more significant in wireless networks because of its limited resources of communication and computation, and the fading that changes the throughput of communication channels. As a result, there is an imperative need of new tools for analysis and synthesis, and new algorithms for control, estimation and decision-making, to take these uncertainties and constraints into consideration and handle the interplay among communication, computation and control. In the past few years, a lot of research efforts have been devoted to this field and significant advancement has been made. This special issue intends to reflect part of those achievements. Indeed, the special issue consists of 17 papers among which 8 discuss the control over communication networks, 1 investigates the traffic control in communication networks, 3 are concerned with multiagent systems, and 5 deal with wireless sensor networks. All papers were selected from numerous submissions and carefully reviewed.We hope that the special issue will promote the research interest in networked sensing, actuation and control systems, and foster new applications of networked systems.
