Classical Feedback Control with Nonlinear Multi-Loop Systems describes the design of high-performance feedback control systems, emphasizing the frequency-domain approach widely used in practical engineering. It presents design methods for high-order nonlinear single- and multi-loop controllers with efficient analog and digital implementations. Bode integrals are employed to estimate the available system performance and to determine the ideal frequency responses that maximize the disturbance rejection and feedback bandwidth. Nonlinear dynamic compensators provide global stability and improve transient responses. This book serves as a unique text for an advanced course in control system engineering, and as a valuable reference for practicing engineers competing in today's industrial environment.

Aviation safety and astronautics safety are taught as technical subjects informed, for the most part, by quantitative methods. Here, as in other fields, safety is often framed as an engineering problem requiring mathematics-informed solutions. This book argues that the socio-technical approach, encompassing theories grounded in sociology and psychology - such as active learning, high-reliability organising, mindfulness, leadership, followership and empowerment - has much to contribute to the safety performance of these vital industries. It sets out to inspire professionals to embed the whole-system approach into design and operation regimen and describes the reputational and financial benefits to manufacturers and operators that accrue from adopting a whole-system approach to design and operation. The book defines the socio-technical approach to risk assessment and management in aviation and astronautics (astronautics is taken to mean "the design and operation of vehicles for use beyond the earth's atmosphere"), then demonstrates the strengths and weaknesses of this approach through case studies of, for example, the Boeing 737MAX-8 accidents and the loss of the SpaceShipTwo orbiter. Grounding the discourse in familiar case studies engages busy aviation and astronautics professionals. The book's arguments are explained in such a way that they are readily comprehensible to non-experts. Key concepts are defined within a glossary. Photographs, charts and diagrams illustrate key points. Written for a practitioner audience, specifically aviation and astronautics professionals, this book provides a valuable and accessible social sciences perspective on safety that will be directly relevant to their roles.

The author offers practical coverage of vibration stresses and stress-induced displacements, isolation of sensitive components, and evaluation of elastic instability, fatigue and fracture as potential failure modes that arise in mechanical designs and aerospace. The approach taken is particularly useful in the early design stage - the physical problem is defined via known parameters, and a methodology is given for determining the unknown quantities and relating them to specified limiting values and failure modes to obtain an acceptable design. Many of the calculations can be performed on a PC or programmable calculator.

Discrete and continuous isospectral systems are discussed using a simple multi-degree of freedom spring-mass system followed by illustration of isospectral beams and their solution through evolutionary computing. Next, it addresses axially loaded Euler-Bernoulli beams and aims to find isospectral counterparts of these systems. The practical application of these isospectral systems for vibration testing and for finding new closed form solutions is discussed. A considerable part of the book is devoted to isospectral rotating beams and their non-rotating analogs including Rayleigh beams.

This book studies the dynamics of 2D objects moving through turbulent fluids. It examines the decay of turbulence over extended time scales, and compares the dynamics of non-spherical particles moving through still and turbulent fluids. The book begins with an introduction to the project, its aims, and its relevance for industrial applications. It then discusses the movement of planar particles in quiescent fluid, and presents the numerous methodologies used to measure it. The book also presents a detailed analysis of the falling style of irregular particles, which makes it possible to estimate particle trajectory and wake morphology based on frontal geometry. In turn, the book provides the results of an analysis of physically constrained decaying turbulence in a laboratory setting. These results suggest that large-scale cut-off in numerical simulations can result in severe bias in the computed turbulent kinetic energy for long waiting times. Combining the main text with a wealth of figures and sketches throughout, the book offers an accessible guide for all engineering students with a basic grasp of fluid mechanics, while the key findings will also be of interest to senior researchers.

For over 80 years, the National Society of Professional Engineers (NSPE) has been a leader in the promotion of ethical practice within the field of engineering. One of the Society's greatest contributions is the formation and adoption of the NSPE Code of Ethics. But the code, with its six "Fundamental Canons," is only truly instructive if engineers can bridge the gap between principles and action. Here there is no substitute for personal reflection on the ethical and philosophical issues that underlie the code. If done well, such reflection provides an indispensable basis for moral problem solving. Beyond the Code: A Philosophical Guide to Engineering Ethics is designed to complement the NSPE Code of Ethics by helping readers "go beyond" in their understanding of the philosophical issues bound up in the code. Each chapter addresses one of the Fundamental Canons of the NSPE code, and provides a philosophical analysis of the various parts of each canon by employing contemporary and classical texts. This unique approach to engineering ethics guides students and professionals in their readings of the appended selections to refine their understanding of the code in order to apply it to the practical challenges of today's engineers. Key Features: Is the first introduction to engineering ethics that helps students understand and apply the NSPE Code of Ethics to engineering practice Includes a Preface from Arthur E. Schwartz, NSPE Deputy Executive Director and General Counsel, and NAFE Executive Director As a hybrid text, includes primary philosophical texts with extensive introductions and guided reading questions from the book's three authors Offers case studies from the NSPE Board of Ethical Review, allowing students to see a direct connection between the issues discussed in the text and real-world engineering practice Includes the following pedagogical aids: "Key Terms and Concepts" for each chapter "Preparing to Read" sections before each primary source reading "Guided Reading Questions" after each primary source reading "Going Beyond-Our Questions for a Deep Dive" after each case study.
