An Experimental Identification Method for Piezoelectric Shunt Damping

Abstract

This paper considers a method to identify the parameters for the piezoelectric shunt damping. Employing the self-sensing actuator methodology, the proposed method uses the piezoelectric element for shunt damping as a sensor/actuator, and only a simple circuit is required for the experimental setup. From the frequency response obtained from the voltage signals of the circuit, the parameters are calculated simply by the linear least squares method. The experimental results demonstrate the efficiency of the proposed method.
