Abstract: This paper presents the design and experimental implementation of simultaneous fast output sampling feedback controller to minimise structural vibration using collocated piezoelectric actuator and sensor. The linear dynamic model of piezoelectric bonded cantilever beams is obtained using online recursive least square parameter estimation. A digital control system that consists of simulink modelling software and dSPACE 1104 controller board is used for identification and control. The performance of simultaneous controller is evaluated by considering three structure models. These models are obtained by introducing parameter variation in length and mass of a single cantilever beam structure. The effectiveness of the controller is demonstrated experimentally by exciting the structures at resonance.
