Control of Wave and Beam PDEs: The Riesz Basis Approach (Communications and Control Engineering)
by Bao-Zhu Guo Jun-Min WangControl of Wave and Beam PDEs is a concise, self-contained introduction to Riesz bases in Hilbert space and their applications to control systems described by partial differential equations (PDEs). The authors discuss classes of systems that satisfy the spectral determined growth condition, the problem of stability, and the relationship between fulfillment of the condition and stability. Using the (fundamental) Riesz-basis property, the book shows how controllability, observability, stability, etc., can be derived for a linear system. The text provides a crash course in the mathematical theory of Riesz bases so that a reader can quickly understand this powerful method of dealing with linear PDEs. It introduces several important methods for achieving the Riesz basis property through spectral analysis, as well as new approaches including treatment of systems coupled through boundary weak connections. The book moves from a discussion of mathematical preliminaries through bases in Hilbert Spaces to applications to Euler–Bernoulli and Rayleigh beam equations and hybrid systems. The final chapter expands the use of the book’s methods to applications in other systems. Many typical examples, representing physical systems, are discussed in the text. The book is suitable not only for applied mathematicians seeking a powerful tool to understand control systems, but also for control engineers interested in the mathematics of PDE systems.
Control of the Gravitational Wave Interferometric Detector Advanced Virgo (Springer Theses)
by Julia Casanueva DiazThis book focuses on the development and implementation of the longitudinal, angular and frequency controls of the Advanced Virgo detector, both from the simulation and experimental point of view, which contributed to Virgo reaching a sensitivity that enabled it to join the LIGO-Virgo O2 run in August 2017. This data taking was very successful, with the first direct detection of a binary black hole merger (GW170814) using the full network of three interferometers, and the first detection and localization of a binary neutron star merger (GW170817). The second generation of gravitational wave detector, Advanced Virgo, is capable of detecting differential displacements of the order of 10–21m. This means that it is highly sensitive to any disturbance, including the seismic movement of the Earth. For this reason an active control is necessary to keep the detector in place with sufficient accuracy.
Control over Communication Networks: Modeling, Analysis, and Design of Networked Control Systems and Multi-Agent Systems over Imperfect Communication Channels (IEEE Press Series on Control Systems Theory and Applications)
by Lihua Xie Liang Xu Qinglei Hu Jianying ZhengControl over Communication Networks Advanced and systematic examination of the design and analysis of networked control systems and multi-agent systems Control Over Communication Networks provides a systematic and nearly self-contained description of the analysis and design of networked control systems (NCSs) and multi-agent systems (MASs) over imperfect communication networks, with a primary focus on fading channels and delayed channels. The text characterizes the effect of communication channels on the stability and performance of NCSs, and further studies the joint impact of communication channels and network topology on the consensus of MASs. By integrating communication and control theory, the four highly-qualified authors present fundamental results concerning the stabilization of NCSs over power-constrained fading channels and Gaussian finite-state Markov channels, linear-quadratic optimal control of NCSs with random input gains, optimal state estimation with intermittent observations, consensus of MASs with communication delay and packet dropouts, and synchronization of delayed Vicsek models. Simulation results are given in each chapter to demonstrate the developed analysis and synthesis approaches. The references are comprehensive and up-to-date, enabling further study for readers. Topics covered in Control Over Communication Networks include: Basic foundational knowledge, including control theory, communication theory, and graph theory, to enable readers to understand more complex topics The stabilization, optimal control, and remote state estimation problems of linear systems over channels with fading, signal-to-noise constraints, or intermittent measurements Consensus problems of MASs over fading/delayed channels, with directed and undirected communication graphs Control Over Communication Networks provides a valuable unified platform for understanding the analysis and design of NCSs and MASs for researchers, control engineers working on control systems over communication networks, and mechanical engineers working on unmanned systems. Preliminary knowledge of linear system theory and matrix analysis is required.

Control: The Dark History And Troubling Present Of Eugenics
by Adam RutherfordHow did an obscure academic idea pave the way to the Holocaust within just fifty years? Control is a book about eugenics, what geneticist Adam Rutherford calls “a defining idea of the twentieth century.” Inspired by Darwin’s ideas about evolution, eugenics arose in Victorian England as a theory for improving the British population, and quickly spread to America, where it was embraced by presidents, funded by Gilded Age monopolists, and enshrined into racist American laws that became the ideological cornerstone of the Third Reich. Despite this horrific legacy, eugenics looms large today as the advances in genetics in the last thirty years—from the sequencing of the human genome to modern gene editing techniques—have brought the idea of population purification back into the mainstream. Eugenics has “a short history, but a long past,” Rutherford writes. The first half of Control is the history of an idea, from its roots in key philosophical texts of the classical world all the way into their genocidal enactment in the twentieth century. The second part of the book explores how eugenics operates today, as part of our language and culture, as part of current political and racial discussions, and as an eternal temptation to powerful people who wish to improve society through reproductive control. With disarming wit and scientific precision, Rutherford explains why eugenics still figures prominently in the twenty-first century, despite its genocidal past. And he confronts insidious recurring questions—did eugenics work in Nazi Germany? And could it work today?—revealing the intellectual bankruptcy of the idea, and the scientific impossibility of its realization.
Control: The Dark History and Troubling Present of Eugenics
by Adam Rutherford* FROM THE SUNDAY TIMES BESTSELLING AUTHOR OF HOW TO ARGUE WITH A RACIST *Throughout history, people have sought to improve society by reducing suffering, eliminating disease or enhancing desirable qualities in their children. But this wish goes hand in hand with the desire to impose control over who can marry, who can procreate and who is permitted to live. In the Victorian era, in the shadow of Darwin's ideas about evolution, a new full-blooded attempt to impose control over our unruly biology began to grow in the clubs, salons and offices of the powerful. It was enshrined in a political movement that bastardised science, and for sixty years enjoyed bipartisan and huge popular support. Eugenics was vigorously embraced in dozens of countries. It was also a cornerstone of Nazi ideology, and forged a path that led directly to the gates of Auschwitz. But the underlying ideas are not merely historical. The legacy of eugenics persists in our language and literature, from the words 'moron' and 'imbecile' to the themes of some of our greatest works of culture. Today, with new gene editing techniques, very real conversations are happening - including in the heart of British government - about tinkering with the DNA of our unborn children, to make them smarter, fitter, stronger. CONTROL tells the story of attempts by the powerful throughout history to dictate reproduction and regulate the interface of breeding and society. It is an urgently needed examination that unpicks one of the defining and most destructive ideas of the twentieth century. To know this history is to inoculate ourselves against its being repeated.

Controllability and Minimum Energy Control (Studies in Systems, Decision and Control #162)
by Jerzy KlamkaThe book offers a comprehensive overview of controllability problems and minimum energy control for broad classes of dynamical systems, including linear, semilinear and nonlinear systems, which are important for modeling systems in automatic control, electrical engineering, mechanics and informatics. It develops the theory of controllability for both finite and infinite dimensional dynamical systems described by differential state equation, and studies in detail functional analysis and matrix algebra, which provide essential and effective tools for the new solutions of a number of important controllability problems. The theoretical results are illustrated by examples throughout the book. Primarily intended for academic researchers working in mathematical control theory, the self-contained text is easily accessible and particularly interesting for control engineering and applied mathematics graduates.
Controllability and Stabilization of Parabolic Equations (Progress in Nonlinear Differential Equations and Their Applications #90)
by Viorel BarbuThis monograph presents controllability and stabilization methods in control theory that solve parabolic boundary value problems. Starting from foundational questions on Carleman inequalities for linear parabolic equations, the author addresses the controllability of parabolic equations on a variety of domains and the spectral decomposition technique for representing them. This method is, in fact, designed for use in a wider class of parabolic systems that include the heat and diffusion equations. Later chapters develop another process that employs stabilizing feedback controllers with a finite number of unstable modes, with special attention given to its use in the boundary stabilization of Navier–Stokes equations for the motion of viscous fluid. In turn, these applied methods are used to explore related topics like the exact controllability of stochastic parabolic equations with linear multiplicative noise. Intended for graduate students and researchers working on control problems involving nonlinear differential equations, Controllability and Stabilization of Parabolic Equations is the distillation of years of lectures and research. With a minimum of preliminaries, the book leaps into its applications for control theory with both concrete examples and accessible solutions to problems in stabilization and controllability that are still areas of current research.
Controllability of Singularly Perturbed Linear Time Delay Systems (Systems & Control: Foundations & Applications)
by Valery Y. GlizerThis monograph provides a comprehensive analysis of the control of singularly perturbed time delay systems. Expanding on the author’s previous work on controllability of linear systems with delays in the state and control variables, this volume’s comprehensive coverage makes it a valuable addition to the field. Each chapter is self-contained, allowing readers to study them independently or in succession.After a brief introduction, the book systematically examines properties of different classes of singularly perturbed time delay systems, including linear time-dependent systems with multiple point-wise and distributed state delays. The author then considers more general singularly perturbed systems with state and control delays. Euclidean space controllability for all of these systems is also discussed, using numerous examples from real-life models throughout the text to illustrate the results presented. More technically complicated proofs are presented in separate subsections. The final chapter includes a section dedicated to non-linear time delay systems.This book is ideal for researchers, engineers, and graduate students in systems science and control theory. Other applied mathematicians and researchers working in biology and medicine will also find this volume to be a valuable resource.

Controllable Nonlinear Waves in Graded-Index Waveguides (SpringerBriefs in Applied Sciences and Technology)
by Thokala Soloman RajuThis book highlights the dynamical behavior of self-similar waves in graded-index waveguides in (1+1)-dimensions and (2+1)-dimensions. The mechanism to control these optical similaritons by tailoring the tapering profile is presented. Various nonlinear waves like rogons, butterfly-shaped, and dromion-like waves and their controllable behavior are discussed in detail. The phenomenon of unbreakable Parity-Time symmetry of some of these waves has been delineated for different variety of solvable potentials. Compression of these exotic waves has been demonstrated for dispersion decreasing fiber and periodic management of dispersion and nonlinearity parameters. Competing cubic-quintic nonlinearity scenario and its potential implication on the dynamics of these similaritons has been described in detail. Symbiotic self-similar rogue waves have been discussed in (2+1)-dimensional garded-index waveguide. The book also includes numerical simulations that complement these analytical insights.

Controlled Atmosphere Transmission Electron Microscopy: Principles and Practice
by Thomas Willum Hansen Jakob Birkedal WagnerThis book illustrates the practical workings of environmental transmission electron microscopy (ETEM) from history and instrument design through to solving practical problems. Aspects of instrument design, performance, and operating procedures are covered, together with common problems and pitfalls of the technique. Not only will a properly operated instrument and a carefully set up experiment provide new insight into your specimen, but the ability to observe the specimen in its natural habitat will be essential to meeting specific design criteria for the development of the next generation of materials. Over the past five decades, transmission electron microscopy (TEM) under environmental conditions relevant to a particular sample has been of increasing interest. Symposia dealing with the topic are now among the best attended at international microscopy conferences. Since typical operating modes for the ETEM require the sample be subjected to a harsh environment consisting of corrosive gases and high temperatures, the challenges of adapting and operating the instrument for observation under dynamic operating conditions are numerous. However, careful consideration of the interaction of the electrons with the gases and sample, as well as the gases with the microscope components, can lead to highly rewarding results. In Controlled Atmosphere Transmission Electron Microscopy, leading experts help you to perform successful experiments using the ETEM, and to interpret and understand the results.

Controlled Environment Horticulture: Improving Quality of Vegetables and Medicinal Plants
by Christoph-Martin GeilfusAn understanding of crop physiology and ecophysiology enables the horticulturist to manipulate a plant’s metabolism towards the production of compounds that are beneficial for human health when that plant is part of the diet or the source of phytopharmaceutical compounds. The first part of the book introduces the concept of Controlled Environment Horticulture as a horticultural production technique used to maximize yields via the optimization of access to growing factors. The second part describes the use of this production technique in order to induce stress responses in the plant via the modulation of these growing factors and, importantly, the way that this manipulation induces defence reactions in the plant resulting in the production of compounds beneficial for human health. The third part provides guidance for the implementation of this knowledge in horticultural production.
