Résumé
Flexible mechanical systems experience undesirable vibration in response to environmental and operational forces. The very existence of vibrations can limit the accuracy of sensitive instruments or cause significant errors in applications where high-precision positioning is essential so in many situations control of vibrations is a necessity. Piezoelectric transducers have been used in countless applications as sensors, actuators, or both. When traditional passive vibration control techniques fall to meet requirements, piezoelectric transducers in conjunction with feedback controllers can be used effectively to suppress vibrations. Piezoelectric Transducers for Vibration Control and Damping presents recent developments in vibration control systems that employ embedded piezoelectric sensors and actuators. In particular, it covers various ways in which active vibration control systems can be designed for piezoelectric laminated structures, paying distinct attention to how such control systems can be implemented in real time. The text contains numerous examples and experimental results obtained from laboratory-scale apparatus, with details of how similar setups can be built. Features and topics : An overview of piezoelectricity. Modelling of flexible structures with embedded piezoelectric sensors and actuators. Feedback control of structural vibration using PPF and resonant controllers. A comprehensive treatment of piezoelectric shunt damping systems using systems-theoretic tools. A paradigm for designing active high-performance piezoelectric shunts. Innovative techniques to deal with hysteresis in piezoelectric transducers. Instrumentation for piezoelectric sensors and actuators. Applications in atomic force and scanning tunneling microscope. An essential text and reference for graduates, researchers, and professionals working in mechanical engineering, aerospace engineering and mechatronics disciplines, this book will be a specially useful resource for scientists and engineers engaged in vibration control research. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for- researchers to present an extended exposition of new work in ail aspects of Industrial control.
