Paper Abstract

Using dirct and inverse piezoelectric effects of distributed piezoelectric films simultaneously, active flexible structures which posess vibration damping ability can be able to construct. However, conventional studies are limited to the control of relatively small (micron-order) displacements of thin flexible structures as well as numerical studies by handling controller design of software aspects. In this paper, several fundamental active vibration control principles, which will be valid in actual implementation, of smart flexible structures using piezoelectric films as distributed sensor/actuator have been developed. By applying each of these methods, it was verified that the enough vibration control effects were actually obtained and the theory agrees well with the experiment.
