Paper Abstract

An experimental study for the active vibration control of intelligent structures subject to external excitations using piezoelectric sensors and actuators is presented. A simply supported piezoelectric intelligent plate is used as the controlled structures. The transfer function model of intelligent plates is derived and an analogy for modal control between the piezoelectric structures and general ones is established. Based on this concept and by experiment development, a "quasi-independent modal control" technique is presented, attempting to approach, with hardware as simple as possible, independent modal control. The experiment progress and results for multiple modal damping control show its effectiveness and practicality.
