dc.description.abstract | Active vibration control of intelligent laminated composite plates is performed experimentally. Laminated composite plate is modeled by the system identification method. For the system identification process, the laminated composite plate is excited by two piezoelectric actuators with PRBS signals. At the same time, the displacement of the laminated composite plate is measured by a gap sensor. From these excited PRBS signals and the measured displacement sequence, system parameters of the laminated composite plate are estimated using a recursive prediction error method. Model of the laminated composite plate with two piezoelectric actuators is assumed to be the form of ARMAX. From the estimated ARMAX model, a state space equation of the observable canonical form is obtained. With this state space equation, a controller and an observer for active vibration control is designed using the optimal control method. Controller and observer are implemented on a digital system. Experiments on the vibration control are performed with changing the outer layer fiber orientation of intelligent composite plates. | - |
