Supervisory Control of Discrete-Event Systems
Author: W. Murray WonhamPublisher: Springer
ISBN: 3319774522
Category : Technology & Engineering
Languages : en
Pages : 487
Book Description
This book shows how supervisory control theory (SCT) supports the formulation of various control problems of standard types, like the synthesis of controlled dynamic invariants by state feedback, and the resolution of such problems in terms of naturally definable control-theoretic concepts and properties, like reachability, controllability and observability. It exploits a simple, abstract model of controlled discrete-event systems (DES) that has proved to be tractable, appealing to control specialists, and expressive of a range of control-theoretic ideas. It allows readers to choose between automaton-based and dually language-based forms of SCT, depending on whether their preference is for an internal-structural or external-behavioral description of the problem. The monograph begins with two chapters on algebraic and linguistic preliminaries and the fundamental concepts and results of SCT are introduced. To handle complexity caused by system scale, architectural approaches—the horizontal modularity of decentralized and distributed supervision and the vertical modularity of hierarchical supervision—are introduced. Supervisory control under partial observation and state-based supervisory control are also addressed; in the latter, a vector DES model that exploits internal regularity of algebraic structure is proposed. Finally SCT is generalized to deal with timed DES by incorporating temporal features in addition to logical ones. Researchers and graduate students working with the control of discrete-event systems or who are interested in the development of supervisory control methods will find this book an invaluable aid in their studies. The text will also be of assistance to researchers in manufacturing, logistics, communications and transportation, areas which provide plentiful examples of the class of systems being discussed.

Supervisory Control of Concurrent Systems

ISBN: 0817644881
Category : Technology & Engineering
Languages : en
Pages : 289
Book Description
This book addresses the design of such tools for correct-by-construction synthesis of supervisors for systems and specifications represented in the discrete-event framework. The approach employed uses Petri nets as discrete-event models and structural methods for the synthesis of supervisors, and may lead to significant computational benefits. Highlighting recent progress in the design of supervisors by structural methods, the book represents a novel contribution to the field. One of the main features of the presentation is the demonstration that structural methods can address a variety of supervisor specifications under diverse supervision settings.
Supervisory Control: Problems, Theory and Experiment for Application to Human-Computer Interaction in Undersea Remote Systems

Book Description
This technical report provides an overview of a four-year theoretical and experimental research project on human-computer cooperation in remote control of undersea manipulators and vehicles. The report puts forth a theoretical framework for viewing supervisory control in terms of a hierarchical interaction of three fundamentally different types of control loops: (1) interaction of a human supervisor with a high level computer; (2) interaction between the high level and one or more low level computers; and (3) interaction of the low level computers with the environment as mediated through artificial sensors and effectors. The perspective is one of coordinated allocation of human and artificial resources to various functions at various levels and times within given tasks. Numerous problems are discussed in conjunction with human and computer cognition, display, command and control, matching capabilities to tasks and evaluation aspects. Experiments performed in our laboratory on human supervisory control of remote undersea manipulators, vehicles and dynamic processes are reviewed briefly in relation to the theoretical constructs. These draw upon already published detailed reports of each experiment. (Author).

Book Description
The Internet plays a significant and growing role in real-time industrial manufacturing, scheduling and management. A considerable research effort has led to the development of new technologies that make it possible to use the Internet for supervision and control of industrial processes. Internet-based Control Systems addresses the challenges that need to be overcome before the Internet can be beneficially used not only for monitoring of but also remote control industrial plants. New design issues such as requirement specification, architecture selection and user-interface design are dealt with. Irregular data transmission and data loss and, in extreme cases, whole-system instability may result from Internet time-delay; this book guards against such phenomena from both computer science and control engineering perspectives. Security breaches and safety risks in an Internet-based control system could have very serious consequences and the author gives specific advice for avoiding them. This book is unique in bringing together multiple strands of research, mainly from computer science and control engineering, into an over-arching study of the entire subject. Practical perspectives are explored both through case studies in several chapters and through real applications including: · robot arm control; · web-based simulator for a catalytic reactor; · virtual supervision parameter control of a water tank system; · model predictive control for a process control unit; · remote control performance monitoring and maintenance; · remote control system design and implementation; Internet-based Control Systems is a useful introduction and guide for researchers in control engineering and computer science and developers of real-time Internet-enabling software. It can also be used for teaching a final year option or elective on Internet-enabled real-time system design, or as an advanced example of real-time software design for graduates.
Frontiers in Robotics Research

Book Description
Robotics began as a science fiction creation which has become quite real, first in assembly line operations such as automobile manufacturing, aeroplane construction etc. They have now reached such areas as the Internet, ever-multiplying-medical uses and sophisticated military applications. Control of today's robots is often remote which requires even more advanced computer vision capabilities as well as sensors and interface techniques. Learning has become crucial for modern robotic systems as well. This book brings together leading research in this exciting field.
