Dynamic control of kinematically excited laminated, thin-walled beam using macro fibre composite actuator

Abstract

In this study, the problem of vibration reduction in a cantilever beam under kinematic excitation is considered. Numerical studies and laboratory tests are performed on a composite beam with an embedded macro fibre composite actuator. Select methods of vibration reduction, that is, proportional (P), derivative (D), and PD controls, are presented. The properties of the control system are described using the first-order inertial term. The experimental results are used to identify the time constant and verify the proposed concept. Finally, the possibility of vibration control is demonstrated numerically using the finite element model.
