Thin Plate Active Vibration Control

Abstract

This article investigates active vibration control of thin plates using piezoceramic actuators. The piezoceramic actuator is in disc form and is tightened by screws to the centre of plate which is a piece of stainless steel sheet excited by small shaker. Paper describes method of identification of the laboratory model and also creation of approximation mathematical model together with basic algorithm which is designed the first four modes. As the result is presented good effect for first, third and four mode, and zero effect on second mode, which is probably caused by piezoactuator position.
