A straight composite beam under the action of lateral forces is considered. A piezoelectric layer is used to control the excited motion of the beam. A nonlinear initial-boundary-value problem for the deยฏection is derived, which is approximated by a set of nonlinear ordinary dierential equations. The
This paper presents an actuator with a sensor for controlling vibrations of machines. It consists of a voice coil-type electromagnetic actuator connected to a piezoelectric sensor and a coil spring. The actuator is used for controlling a motor laid on the beam. The sensor detects the disturbance for
A robust design methodology is presented for the control of ยฏexible structures by the use of piezoelectric actuators. The ยฎnite element modeling and analysis of the piezoelectric media are carried out via Hamilton's principle. Finite element equations are utilized for the piezoelectric control of ยฏe
Active control of structural acoustic pressure in a rectangular cavity with a flexible beam is simulated numerically. The wave equation of the acoustic pressure and the equation of motion of the beam are approximated via the series expansions, and is then expressed in state space form. The control o
