This book is an integrated treatment of its selected research in nonlinear networked systems and control. It progresses from stabilization and regulation to synchronization, providing a systematic approach connecting work in the field. It covers essential control problems methodically, emphasizing problem formulation, techniques, and their interrelationships. Starting with fundamental concepts, the book builds a solid understanding before delving into advanced research areas, facilitating learning and preparing readers for real-world challenges in robotics, automated vehicles, smart grids, and neural networks. This book balances technical accuracy, difficulty, and depth, to make complex theories accessible. The book supports a rigorous theoretical presentation of control design methods with numerous examples. It addresses cutting-edge research topics and prepares readers for advanced studies. By emphasizing both theoretical foundations and practical relevance, it equips readers to engage critically with current research and, further, to develop their own innovations in nonlinear networks and their control. Graduate students in engineering and applied mathematics and practitioners and academic theorists in electrical, aerospace, mechanical, and chemical engineering will find this book a valuable reference.
