Abstract: In this paper vibration of beam are controlled using LQR controls. Smart beam is modeled using piezoelectric patches. Harmonic and modal analysis is done in a finite element tool (ANSYS 14.5). The dynamic behavior of smart beam is obtained using a system identification technique. The feedback control algorithm is implemented using National Instrument CRIO 9022 controller. It is observed that with this controller of 30% reductions are obtained in vibration amplitude. The presented control method is effective to suppress the vibration of the beam smart beam.
