"Vibration Control of Active Structures" is a second edition textbook that bridges the gap between structural dynamics and control theory, focusing on the potential of smart materials for vibration control. The book provides a clear and accessible overview of the fundamentals of vibration control, emphasizing the use of collocated actuator/sensor pairs, which are often underestimated in control theory. It covers key concepts in structural dynamics, actuator technologies, control strategies, and the application of active control in various engineering fields. The text is written for first-year graduate students, with some chapters accessible to final-year undergraduates, and emphasizes readability and clarity. The book includes chapters on structural dynamics, smart materials, control strategies, active damping, vibration isolation, state-space methods, frequency domain analysis, optimal control, controllability and observability, stability, semi-active control, and applications. It also discusses the use of smart materials in vibration control, including piezoelectric actuators and sensors, and explores various control techniques such as feedback, feedforward, and optimal control. The second edition includes three new chapters on active isolation, semi-active control, and cable structure control, as well as additional material on piezoelectric structures and distributed sensors. The author, André Preumont, emphasizes the importance of accurate prediction of transmission zeros in control system performance and highlights the challenges of predicting open-loop zeros. He also discusses the impact of model truncation and local effects on control performance. The book is written with the aim of providing a practical and comprehensive guide to vibration control, with a focus on real-world applications and the use of smart materials. The second edition builds on the success of the first edition, incorporating new material and expanding on key topics in the field of active vibration control."Vibration Control of Active Structures" is a second edition textbook that bridges the gap between structural dynamics and control theory, focusing on the potential of smart materials for vibration control.
