Control Design of Multiagent Discrete-Time Systems (Studies in Systems, Decision and Control #387)

by MagdiSadek Mahmoud Bilal J. Karaki

This book describes an effective approach to the cooperative and coordinated control of multivehicle systems. This rigorous analytic approach guarantees the stability of coordinated and cooperating vehicles using distributed protocols and uses low-energy, event-triggered mechanisms for networked vehicle control. The text covers: design of a cooperative protocol to achieve consensus for multivehicle systems, allowing cooperation that is resistant to the effects of packet loss and/or adversarial attack; analysis and synthesis of an event-triggering mechanism for cooperative multivehicle systems over uncertain networks; and the problem of distributed leader-following consensus and methods for compelling multivehicle systems to reach consensus. Throughout the book, cooperation problems are transformed into stability problems. Lyapunov theory is used to guarantee cooperation among agents. The distributed approach is applied to triggering mechanisms, the cooperation process, and the impact of cyber-attacks. Discrete-time analysis shows how the event-based structure can be designed to match the performance of continuous-time counterparts. The book details applications and computer simulation with several practical examples. This book is of interest to a wide audience from the graduate student, through the academic researcher to the industrial practitioner, all of them sharing a common interest in the stability and security of multiagent systems.

Control Engineering: From The Basics To The Applications (Advanced Textbooks in Control and Signal Processing)

by László Keviczky Ruth Bars Jenő Hetthéssy Csilla Bányász

This book offers fundamental information on the analysis and synthesis of continuous and sampled data control systems. It includes all the required preliminary materials (from mathematics, signals and systems) that are needed in order to understand control theory, so readers do not have to turn to other textbooks. Sampled data systems have recently gained increasing importance, as they provide the basis for the analysis and design of computer-controlled systems. Though the book mainly focuses on linear systems, input/output approaches and state space descriptions are also provided. Control structures such as feedback, feed forward, internal model control, state feedback control, and the Youla parameterization approach are discussed, while a closing section outlines advanced areas of control theory. Though the book also contains selected examples, a related exercise book provides Matlab/Simulink exercises for all topics discussed in the textbook, helping readers to understand the theory and apply it in order to solve control problems. Thanks to this combination, readers will gain a basic grasp of systems and control, and be able to analyze and design continuous and discrete control systems.

Control Methods for Electrical Machines

by René Husson

The type of control system used for electrical machines depends on the use (nature of the load, operating states, etc.) to which the machine will be put. The precise type of use determines the control laws which apply. Mechanics are also very important because they affect performance. Another factor of essential importance in industrial applications is operating safety. Finally, the problem of how to control a number of different machines, whose interactions and outputs must be coordinated, is addressed and solutions are presented. These and other issues are addressed here by a range of expert contributors, each of whom are specialists in their particular field. This book is primarily aimed at those involved in complex systems design, but engineers in a range of related fields such as electrical engineering, instrumentation and control, and industrial engineering, will also find this a useful source of information.

Control of Complex Nonlinear Systems with Delay (Springer Theses)

by Philipp Hövel

This research addresses delay effects in nonlinear systems, which are ubiquitous in various fields of physics, chemistry, biology, engineering, and even in social and economic systems. They may arise as a result of processing times or due to the finite propagation speed of information between the constituents of a complex system. Time delay has two complementary, counterintuitive and almost contradictory facets. On the one hand, delay is able to induce instabilities, bifurcations of periodic and more complicated orbits, multi-stability and chaotic motion. On the other hand, it can suppress instabilities, stabilize unstable stationary or periodic states and may control complex chaotic dynamics. This thesis deals with both aspects, and presents novel fundamental results on the controllability of nonlinear dynamics by time-delayed feedback, as well as applications to lasers, hybrid-mechanical systems, and coupled neural systems.

Control of Crop Diseases

by W. R. Carlile A. Coules

Thoroughly revised and updated to reflect current and emerging practices, this book explores modern methods of disease control in field and glasshouse crops. It outlines the major crop diseases, with a particular emphasis on those features of symptomology and life cycle that are most relevant to the development of control measures. Modern diagnostic techniques are considered, focusing on developments in nucleic acid and immunological based procedures and their use in plant quarantine and certification schemes. The potential impact of these advances in molecular technology on plant breeding and disease resistance is also covered. Fungicides are a central part of disease control in the EU and, as such, a comprehensive account of their use forms an important part of the text, along with strategies to minimise the incidence of fungicide resistance in pathogen populations. Looking to the future, the book also addresses legislative, environmental and food safety concerns.

The Control of Drugs and Drug Users: Reason or Reaction?

by Ross Coomber

Informed debate on how, why, or even if, drugs and those that use them should be controlled needs an insight into the background of such controls, how effective they have been and what reasonable alternatives there may be. This book seeks to provide such an insight. Reviewing important aspects of past and current drug control policies in Britain and America, the international compliment of expert contributors seek to explore the rationality of the reasoning which produced the initial controls, the continuing relevance of those currently employed, and provide alternative scenarios for future policy.

Control of Fuel Combustion in Boilers (Studies in Systems, Decision and Control #287)

by Artur O. Zaporozhets

This book examines key issues in improving the efficiency of small and medium power boiler units by adding control systems for the fuel combustion process. The original models, algorithms, software and hardware of the system developed for controlling the fuel combustion process are presented. In turn, the book presents a methodology for assessing the influence of climatic factors on the combustion process, and proposes new methods for measuring the thermophysical characteristics, which require taking into account the concentration of oxygen in the air. The system developed here was implemented on a boiler of the NIISTU-5 type, which is widely used for heat power engineering in Ukraine and other Eastern European countries. Given its scope, the book offers a valuable asset for researchers and engineers, as well as lecturers and graduate students at higher education institutions dealing with heat engineering equipment.

Control of Innate and Adaptive Immune Responses during Infectious Diseases

by Julio Aliberti

Upon infection the host needs to mount vigorous immune response against pathogen in order to successfully control its replication. However, once the infectious agent is controlled or eliminated, host cells need to signal the immune system to slow or cease its activities. While vast knowledge has been accumulated through the years on the mechanisms involved in the initiation and effector phases of the immune responses, the pathways triggered in order to modulate or end innate and acquired immunity are becoming more evident as evidence for its relevance comes to surface. Due to its biological power, evidence has surfaced indicating that eventually pathogens may take advantage of such regulatory pathways in order to escape effector mechanisms and progress to persistence. This book will discuss several cellular pathways involved in controlling immune response in the context of infectious diseases, their biological consequences and potential "hijack" of these pathways for the benefit of pathogen leading towards pathogen persistence as opposed to clearance.

Control of Magnetotransport in Quantum Billiards: Theory, Computation and Applications (Lecture Notes in Physics #927)

by Christian V. Morfonios Peter Schmelcher

In this book the coherent quantum transport of electrons through two-dimensional mesoscopic structures is explored in dependence of the interplay between the confining geometry and the impact of applied magnetic fields, aiming at conductance controllability. After a top-down, insightful presentation of the elements of mesoscopic devices and transport theory, a computational technique which treats multiterminal structures of arbitrary geometry and topology is developed. The method relies on the modular assembly of the electronic propagators of subsystems which are inter- or intra-connected providing large flexibility in system setups combined with high computational efficiency. Conductance control is first demonstrated for elongated quantum billiards and arrays thereof where a weak magnetic field tunes the current by phase modulation of interfering lead-coupled states geometrically separated from confined states. Soft-wall potentials are then employed for efficient and robust conductance switching by isolating energy persistent, collimated or magnetically deflected electron paths from Fano resonances. In a multiterminal configuration, the guiding and focusing property of curved boundary sections enables magnetically controlled directional transport with input electron waves flowing exclusively to selected outputs. Together with a comprehensive analysis of characteristic transport features and spatial distributions of scattering states, the results demonstrate the geometrically assisted design of magnetoconductance control elements in the linear response regime.

The Control Of Nature

by John Mcphee

These three essays center around man's influence on nature and how it (nature) fights back. The First essay centers on New Orleans and how man's influence has contributed to it's now demise. Though written in 1989, Mcphee's research pretty much describes how Katrina, or in the case of the book, a theoretical storm, could have been made much less destructive had development been much less. The second article discusses efforts in Iceland to cool lava with saltwater and stop the destruction of a town. The third describes Los Angeles's expansion and possible demise due to run off and mud slides from the San Gabriel mountains. His premise in all three articles basically is, nature will ultimately have the last word in it's ultimate design.

by Enrique Zuazua Jérôme Le Rousseau Roger Brockett Olivier Glass Jean-Michel Coron Fatiha Alabau-Boussouira Piermarco Cannarsa

The term "control theory" refers to the body of results - theoretical, numerical and algorithmic - which have been developed to influence the evolution of the state of a given system in order to meet a prescribed performance criterion. Systems of interest to control theory may be of very different natures. This monograph is concerned with models that can be described by partial differential equations of evolution. It contains five major contributions and is connected to the CIME Course on Control of Partial Differential Equations that took place in Cetraro (CS, Italy), July 19 - 23, 2010. Specifically, it covers the stabilization of evolution equations, control of the Liouville equation, control in fluid mechanics, control and numerics for the wave equation, and Carleman estimates for elliptic and parabolic equations with application to control. We are confident this work will provide an authoritative reference work for all scientists who are interested in this field, representing at the same time a friendly introduction to, and an updated account of, some of the most active trends in current research.
