A periodic output feedback vibration control system for flexible smart cantilever beam is designed by bonding piezoelectric as a sensor/actuator to the structure. The entire structure is modelled by finite element method using piezoelectric beam element which includes sensor/actuator dynamics and a regular beam element. By retaining the first two vibratory modes the reduced order model is obtained in state space form. The effect on vibration modes for various sensor/actuator locations along the beam is observed. The periodic output feedback controller is designed and its performance for various sensor/actuator locations is done.
