The vast majority of control systems built today are embedded; that is, they rely on built-in, special-purpose digital computers to close their feedback loops. Embedded systems are common in aircraft, factories, chemical processing plants, and even in cars-a single high-end automobile may contain over eighty different computers. In such settings, controllers often use shared networks to communicate with each other and with large numbers of sensors and actuators scattered throughout the system. The design of embedded controllers and of the intricate, automated communication networks that support them raises many new questions-practical, as well as theoretical-about network protocols, compatibility of operating systems, and ways to maximize the effectiveness of the embedded hardware.

The Handbook of Networked and Embedded Control Systems, the first of its kind, provides engineers, computer scientists, mathematicians, and students a broad, comprehensive source of information and technology to address many questions and aspects of embedded and networked control. A carefully organized collection of important results, tools, software, and technology, this work unifies into a single reference many scattered articles, websites, and specification sheets-information that might otherwise be difficult to find.

Key topics and features include:

Self-contained, sharply-focused articles; readers have easy access to specific answers to questions without having to read hundreds of pages
Clear structure and presentation of concepts in intuitive order
Separation of material into six main sections-Fundamentals, Hardware, Software, Theory, Networking, and Applications
Case studies, experiments, and examples that provide a multifaceted view of the subject, encompassing computation and communication considerations
Information about commercially availabletools and hardware
Comprehensive bibliographies and index This is an indispensable text for anyone interested in knowing more about embedded and networked control systems. Researchers will appreciate the handbook's up-to-date results in the theory of embedded control; developers and users will value its information on special-purpose computer hardware and operating systems modifications that support real-time control; students will find the systematic organization and wide coverage useful for learning and reference.

Résumé
Thishandbookwasmotivatedinpartbyourexperience(andthatofothers)in performing research and in teaching about networked and embedded control systems (NECS) as well as in implementing such systems. Although NECS along with the technologies that enable themhave become ubiquitous, there are few, if any, sources where a student, researcher, or developer can gain a su?ciently broad view of the subject. Oftentimes, the needed information is scattered in articles, websites, and speci?cation sheets. Such di?culties are perhaps to be expected, given the relative newness of the subject and the diversity of its constitutive disciplines. From control theory and communi- tions, to computer science and electronics, the variety of approaches, tools, and language used by experts in each ?eld often acts as a barrier to und- standing how ideas ?t within the broader context of networked and embedded control. With the above in mind, we have gathered a collection of articles that provide at least an introduction to the important results, tools, software, and technologies that shape the area of NECS. Our goal was to present the most important knowledge about NECS in a book that would be useful to anyone who wants to learn about any aspect of the subject. We hope that we have succeeded and that every reader will ?nd valuable information in the book. Wethanktheauthorsofeachofthechapters.
