The dynamic response of a carbon fibre reinforced plastic [0/+45/-45/0]_s active laminated beam covered by piezoelectric layers is considered. simple collocated displacement control strategy is implemented by letting the active layers work as actuators and sensors and by constructing an analogue control circuit the characteristics of which are given in some detail. The open- and closed-loop steady-state response of the cantilever beam are then experimentally tested in the range of 40-2000 Hz and the effectiveness of the control mechanism is successfully demonstrated.
