Abstract

This paper presents to define a vibration modelling of a PEA using MATLAB-Simulink software based on a single degree freedom mechanical model. The experimental vibration displacement values of PEA have been carried out utilizing the swept-sine signal excitation following the peak values in the signal response measured as contactless by the laser displacement sensor. Harmony between the mathematical modelling and experimental values have been observed from 96.6 to 81.4 % between excitation amplitudes of 0.5 and 3.0 V when the vibration modelling of PEA is normally taken into consideration with a linear working range. Therefore, obtained this vibration modelling could be used as training-testing tool for estimating vibration characterization of an actuator under any excitation voltages.
