Abstract : Attaching a piezoelectric transducer to a vibrating structure, and shunting it with an electric circuit, gives rise to different
passive, semi-passive, and semi-active control techniques. This paper attempts to review the research related to structural
vibration control, via passive, semi-passive, and semi-active control methods. First, the existing electromechanical modeling
is reviewed, along with the modeling methods. These range from lumped parameters, to distributed parameters modeling
of piezostructural systems shunted by electrical networks. Vibration control laws are then discussed, covering passive,
semi-passive, and semi-active control techniques, which are classified according to whether external power is supplied to
the piezoelectric transducers, or not. Emphasis is placed on recent articles covering semi-passive and semi-active control
techniques, based upon switched shunt circuits. This review provides the necessary background material for researchers
interested in the growing field of vibration damping and control, via shunted piezostructural systems.
