The book "Vibration Control of Active Structures" by André Preumont, published in its 2nd edition, aims to bridge the gap between structural dynamics and control communities. It provides an overview of the potential of smart materials (SMART) for sensing and actuating purposes in active vibration control. The book is designed to be accessible to first-year graduate students and emphasizes fundamental concepts and practical applications. Key topics covered include: - Introduction to active versus passive structures, smart materials, and control strategies. - Concepts of structural dynamics, such as equations of motion, vibration modes, and modal decomposition. - Detailed discussions on actuators, piezoelectric materials, and active structures, including proof-mass actuators, reaction wheels, and piezoelectric shells. - Control strategies such as collocated and non-collocated control, active damping, and active vibration isolation. - State space approach, frequency domain analysis, and optimal control methods. - Controllability and observability, stability analysis, and semi-active control using magneto-rheological fluids. - Applications in digital implementation, active damping of truss structures, plate damping, and cable structures. The author emphasizes the importance of accurate prediction of transmission zeros and open-loop zeros in evaluating control system performance. The book also includes new chapters on active isolation, semi-active control, and the control of cable structures, reflecting recent advancements in the field.The book "Vibration Control of Active Structures" by André Preumont, published in its 2nd edition, aims to bridge the gap between structural dynamics and control communities.
