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 fail 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.
