Optimal Location of Piezoelectric Sensors on a Beam by Using Its Response Model

Abstract

The placement of the piezoelectric sensor at the optimal location has a significant influence on the response of the structures to control the vibration of structures. In the current research work, the optimal location of the piezoelectric sensor is determined by studying the response model of a beam with boundary conditions. The formulation of the beam is done in MATLAB software. Then the modal analysis of the beam is obtained. The optimal location of the piezoelectric sensor can be predicted by seeing the natural frequency peaks on the frequency response function curve of the beam. Also, it can be concluded that the location of the piezoelectric sensor cannot be at the nodal point where displacement is zero as it will not provide any effect.
