Multiple mode current flowing passive piezoelectric shunt controller

A method for multiple mode piezoelectric shunt damping will be presented in this paper. The proposed current flowing shunt controller has a number of benefits compared to previous shunt damping schemes; it is simpler to implement and requires small number of passive circuit elements. The passive control strategy is validated through experimentation on two piezoelectric laminated structures. (C) 2002 Elsevier Science Ltd. All rights reserved.
