概要

A smart structure was tested for active microvibration control of a beam which was horizontally suspended by coil springs at both ends and excited by ambient floor vibrations through the springs. A pair of piezoelectric actuators of stack type were embedded in the top and bottom surfaces of the beam near its middle point, and used to control bending moment of the beam. The purpose of the vibration control was to suppress flexural vibration modes of the beam, and rigid body vibration modes of the system were not targets of the control. The controller was designed using the H^∞ control theory. The tests showed that vibrations of the first three flexural modes could be effectively suppressed by the smart structure using a pair of the actuator and an accelerometer.
