Effectiveness of active vibration control on smart plate using a PID controller

Abstract

This paper presents design, development and experimental verification of the active vibration control system of aluminum plate. The active structure consists of an aluminum rectangular plate as the host structure, strain gages as the sensor element and piezoceramic patch as the actuation element. Based on characteristics of integrated elements, the completely active vibration control system is designed and developed. The active vibration control system is controlled on PID control strategy. Control algorithm was implemented on PIC23MX440F256H microcontroller platform. The experiment considers active damping control under periodic excitation. Experiments are conducted to verify the effectiveness of the vibration suppression and to compare the damping effect with different adjustment of PID gains. Experimental results corresponding to develop active vibration control system are presented and affirmed effectiveness of vibration active damping on proposed active structure.
