In this paper a technique for ''instantaneous'' reconstruction of state variables of a flexible beam is proposed. The reconstructor uses spline shape functions to interpolate the available measurements and to take into account the boundary conditions. Unlike usual dynamic observers, this technique d

A finite element model based on third order laminate theory is developed for the active position control and vibration control of composite beams with distributed peizoelectric sensors and actuators. The direct peizoelectric equation is used to calculate the total charge created by the strains on th
Vibration of a laminated composite plate is controlled by passive and active control methods. Stiffness change in composite structures by changes in laminate orientation is used as an example of a passive control method, negative velocity feedback control with the piezoelectric sensor/actuator is us
The "nite element method (FEM) is combined with the Golla}Hughes}McTavish (GHM) model of viscoelastic materials (VEM) to model a cantilever beam with active constrained layer damping treatments. This approach avoids time-consuming iteration in solving modal frequencies, modal damping ratios and resp
This paper addresses the controllability aspect in vibration control of beam structures with piezoelectric actuators. First, we model the beam structure with piezoelectric actuators and establish the corresponding state-coupled equation. Based on the state equation, we propose a controllability inde
