This book provides a broad overview of state-of-the-art research at the intersection of the Koopman operator theory and control theory. It also reviews novel theoretical results obtained and efficient numerical methods developed within the framework of Koopman operator theory. The contributions discuss the latest findings and techniques in several areas of control theory, including model predictive control, optimal control, observer design, systems identification and structural analysis of controlled systems, addressing both theoretical and numerical aspects and presenting open research directions, as well as detailed numerical schemes and data-driven methods. Each contribution addresses a specific problem. After a brief introduction of the Koopman operator framework, including basic notions and definitions, the book explores numerical methods, such as the dynamic mode decomposition (DMD) algorithm and Arnoldi-based methods, which are used to represent the operator in a finite-dimensional basis and to compute its spectral properties from data. The main body of the book is divided into three parts: theoretical results and numerical techniques for observer design, synthesis analysis, stability analysis, parameter estimation, and identification; data-driven techniques based on DMD, which extract the spectral properties of the Koopman operator from data for the structural analysis of controlled systems; and Koopman operator techniques with specific applications in systems and control, which range from heat transfer analysis to robot control. A useful reference resource on the Koopman operator theory for control theorists and practitioners, the book is also of interest to graduate students, researchers, and engineers looking for an introduction to a novel and comprehensive approach to systems and control, from pure theory to data-driven methods.

This book introduces a comprehensive and mathematically rigorous controller design for families of nonlinear systems with time-varying parameters and unstructured uncertainties. Although the presented methodology is general, the specific family of systems considered is the latest, NextGen, unconventional fixed-wing unmanned aircraft with circulation control or morphing wings, or a combination of both. The approach considers various sources of model and parameter uncertainty, while the controller design depends not on a nominal plant model, but instead on a family of admissible plants. In contrast to existing controller designs that consider multiple models and multiple controllers, the proposed approach is based on the 'one controller fits all models' within the unstructured uncertainty interval. The book presents a modeling-based analysis and synthesis approach with additive uncertainty weighting functions for accurate realization of the candidate systems. This differs significantly from existing designs in that it is capable of handling time-varying characteristics. This research monograph is suitable for scientists, engineers, researchers and graduate students with a background in control system theory who are interested in complex engineering nonlinear systems.

This book serves as an introduction to cryocooler technology and describes the principle applications of cryocoolers across a broad range of fields. It covers the specific requirements of these applications, and describes how the advantages and disadvantages of different cryocooler systems are taken into consideration. For example, Stirling coolers tend to be used only in space applications because of their high coefficient of performance, low weight and proven reliability, whilst Gifford-McMahon coolers are used for ground applications, such as in cryopumps and MRI shield cooling applications. Joule-Thomson cryocoolers are used in missile technology because of the fast cool down requirements. The cryocooler field is fast developing and the number of applications are growing because of the increasing costs of the cryogens such as Helium and Neon. The first chapter of the book introduces the different types of cryocoolers, their classification, working principles, and their design aspects, and briefly mentions some of the applications of these systems. This introductory chapter is followed by a number of contributions from prominent international researchers, each describing a specific field of application, the cooling requirements and the cryocooler systems employed. These areas of application include gas liquefaction, space technology, medical science, dilution refrigerators, missile systems, and physics research including particle accelerators. Each chapter describes the cooling requirements based on the end use, the approximate cooling load calculations, the criteria for cryocooler selection, the arrangement for cryocooler placement, the connection of the cooler to the object to be cooled, and includes genuine case studies. Intended primarily for researchers working on cryocoolers, the book will also serve as an introduction to cryocooler technology for students, and a useful reference for those using cryocooler systems in any area of application.

While monitoring of computer-controlled systems is widespread, it is critically important in the cockpit of current passenger aircraft. Such monitoring requires special vigilance for those rare untoward events, which may be new to the pilot and which can have devastating consequences. This book uses a multidisciplinary approach to address this problem of sustaining attention while monitoring. It outlines and explains alternative ways of viewing the processes needed to prevent Human Factors accidents; it examines the use and limitations of cockpit resource management programmes in inducing behavioural and attitudinal changes appropriate for highly automated flight decks. The author's approach deals rigorously with the physiological mechanisms underlying vigilance, arousal and stress, delineating clearly those that are relevant to the monitoring function. The three parts cover: monitoring problems and processes; monitoring measurement and alerting systems; and monitoring management. In the last part the author details management plans and guidance for monitoring assisted systems based on his understanding of the problems of continued human vigilance. Readership: pilots and training pilots; cockpit resource management groups; monitoring management specialists; university aviation departments; road and rail transport groups; those operating nuclear and large process installations.

This book addresses the need to support decision-makers across Africa by promoting awareness of the importance of space technologies and data to African development through the presentation of existing examples where space supports education and healthcare, and by making recommendations for further roll-out of these efforts. This is necessary because of the enduring misconception that space-related research and expenditure competes with other, more pressing, needs on the continent, when in truth space can play a major role in meeting these needs. Accordingly, the book unpacks the United Nations Sustainable Development Goals (SDGs) 2030 and the critical needs they address in the African context. Secondly, it provides an analysis of the African higher education landscape and considers the network of higher education-related SDGs, their targets, and their indicators. Africa's own development plan, Agenda 2063, is also explored. The African higher education landscape is then assessed by way of three models - the Space-Education Equation (SEE), the Benefits to Education by Space Transection (BEST), and the Enhanced Education for Sustainable Development Access and Success (EESDAS) model. The critical role of educational technologies and e-learning in bridging the educational access and success gap is appraised, as is the role of the space sector, and its technologies, applications, and data in African higher education. Finally, it explores e-health and provides an analysis of pertinent technologies required by e-health, past and present, and the opportunities and challenges it presents. Space technology can play a critical role in eliminating the barriers that are currently preventing e-health from playing a more significant role in a developing region such as sub-Saharan Africa.

This book systematically discusses nonlinear interval optimization design theory and methods. Firstly, adopting a mathematical programming theory perspective, it develops an innovative mathematical transformation model to deal with general nonlinear interval uncertain optimization problems, which is able to equivalently convert complex interval uncertain optimization problems to simple deterministic optimization problems. This model is then used as the basis for various interval uncertain optimization algorithms for engineering applications, which address the low efficiency caused by double-layer nested optimization. Further, the book extends the nonlinear interval optimization theory to design problems associated with multiple optimization objectives, multiple disciplines, and parameter dependence, and establishes the corresponding interval optimization models and solution algorithms. Lastly, it uses the proposed interval uncertain optimization models and methods to deal with practical problems in mechanical engineering and related fields, demonstrating the effectiveness of the models and methods.
