Abstract
This paper deals with a vibration control of a thin cylindrical shell, which is one of the fundamental elements in machines and structures. Piezoelectric films are used as sensors and actuators in order to obtain high performance vibration control in low order modes. The optimal length for a piezoelectric film is conducted by finite element analyses, to gain efficiency in a vibration control system developed by using the direct output feedback control scheme. The control effect in vibration experiments are estimated by investigating the sensor output, along with the visual confirmation by using a laser-holographic interferometer.
