In this study, active vibration control of a smart beam equipped with piezoelectric patches which are used as both sensor and actuator is investigated by using linear quadratic regulator (LQR) method. Frequency response function that includes the first natural frequency of the smart beam is obtained by applying exponential sine wave within the specified frequency range to the piezoelectric actuator patch and measuring the response of the system from another piezoelectric patch as a sensor. Then, by using the obtained frequency response function and MATLAB software, an analytic model which characterize the dynamic system of the smart beam is determined. Free and forced vibration control performances of the linear quadratic controllers which are obtained by using different Q and R parameters are tested and compared on Simulink software. Furthermore, by using the best controller which is obtained by considering the output voltage of the controller, an experimental study is conducted. Finally, the experimental results are compared with the simulation outputs.

In this study, vibration characteristics of a smart beam are investigated by using piezoelectric patches as sensors. Smart beam is excited by either impact hammer or piezoelectric patch and the frequency response of the system to these excitations are obtained from a piezoelectric patch used as sensor. The effect of the location of the piezoelectric sensor on frequency response of the system is also presented by choosing different piezoelectric patches along the smart beam. In order to investigate the perfo...
