Additive Manufacturing of Continuous Fiber Reinforced Polymer Composites the additive manufacturing of continuous fiber reinforced polymer composites (CFRPCs), discussing their mechanical behavior, manufacture, structure, performance, and application. The raw materials involved, manufacturing processes for specific CFRPCs (thermoplastic, thermosetting, self-reinforcing), modeling, design, and failure analysis of these materials are each covered at length. An entire chapter is dedicated to their performance based on their structure and design, with lightweight composite structure, shape-morphing composite structure, and electromagnetic wave manipulating structure each studied. Embedded sensing by CFRPCs, mechanical metamaterials, and the applications of CFRPCs in aerospace, consumer products, and industrial tooling are each covered as well.Covers the mechanical behaviors, processing techniques, performance, and applications of additively manufactured continuous fiber reinforced polymer compositesOutlines multi-scale modeling techniques, design considerations, and failure analysis approaches for CFRPCsDiscusses 3D printing of Performance and functions oriented innovative structure, and more

Significant progress has been made on nonlinear control systems in the past two decades. However, many of the existing nonlinear control methods cannot be readily used to cope with communication and networking issues without nontrivial modifications. For example, small quantization errors may cause the performance of a "well-designed" nonlinear control system to deteriorate. Motivated by the need for new tools to solve complex problems resulting from smart power grids, biological processes, distributed computing networks, transportation networks, robotic systems, and other cutting-edge control applications, Nonlinear Control of Dynamic Networks tackles newly arising theoretical and real-world challenges for stability analysis and control design, including nonlinearity, dimensionality, uncertainty, and information constraints as well as behaviors stemming from quantization, data-sampling, and impulses.Delivering a systematic review of the nonlinear small-gain theorems, the text: Supplies novel cyclic-small-gain theorems for large-scale nonlinear dynamic networksOffers a cyclic-small-gain framework for nonlinear control with static or dynamic quantizationContains a combination of cyclic-small-gain and set-valued map designs for robust control of nonlinear uncertain systems subject to sensor noisePresents a cyclic-small-gain result in directed graphs and distributed control of nonlinear multi-agent systems with fixed or dynamically changing topologyBased on the authors’ recent research, Nonlinear Control of Dynamic Networks provides a unified framework for robust, quantized, and distributed control under information constraints. Suggesting avenues for further exploration, the book encourages readers to take into consideration more communication and networking issues in control designs to better handle the arising challenges.

Practical tools and techniques to achieve objectives in safety-critical control This book offers a systematic framework for the safety-critical control of nonlinear uncertain systems, with key contributions such as the development of novel small-gain synthesis and feasible-set reshaping techniques to address interactions between the nominal controlled system and dynamic uncertainties. Incorporating recent advancements in the field, this book showcases the strengths of the proposed framework by tackling key theoretical challenges in safety-critical control across multiple benchmark systems. It further highlights the real-world impact of the developed methods and algorithms through practical applications involving vehicles, quadrotors, and robotic manipulators. All results are supported by laboratory experiments with clear explanations. Written by a team of highly qualified authors, Robust Safety-Critical Control includes: Insights into the challenges of designing controllers that maintain safety while achieving desired objectives, in the presence of uncertainties, nonlinear dynamics, and multiple constraintsA mathematical foundation for robust safety-critical control, presented in the appendices covering quadratic optimization, Lyapunov stability theory, input-to-state stability, and the nonlinear small-gain theoremChapter-by-chapter problem formulations and detailed, rigorous developments of the theory and methods, guiding the reader through the process of addressing the fundamental challengesComprehensive system setups for safety-critical control simulations and experimentsReady-to-use code implementations for key algorithms, including the feasible-reshaping technique and small-gain control methodsRobust Safety-Critical Control is an excellent reference for researchers and graduate students in systems and control, robotics, transportation and AI seeking to expand their knowledge bases. The text is also highly valuable for engineers and practitioners in control engineering, civil and urban engineering, robotics, and manufacturing.
