This book offers a comprehensive overview of vibration control and energy harvesting based on the synchronized switch of piezoelectric transducers, which has been a hot research topic in the past decade. With a self-contained and single-source style, it discusses aspects ranging from the fundamental concepts of electro-mechanical coupling, and energy conversion and damping effects in structures with integrated piezoelectric transducers, to advanced methodologies for their modeling, analysis and experimental validation. Starting from an elementary level of modeling for electro-mechanical systems, this book describes the underlying principle of the synchronized switch damping (SSD) method; its advanced variants, such as SSD with adaptive voltage source and SSD based on negative capacitance; and their application in multi-modal vibration control. It also illustrates the principle of energy harvesting based on piezoelectric materials and enhanced methods of synchronized switch harvesting. As such, it offers a valuable resource for researchers and graduate students working on advanced piezoelectric-based vibration-suppression systems, and for senior undergraduate students interested in the fundamentals of vibration damping and smart structures.
