The main aim of the paper is study on flexural vibration reduction of a laminated cantilever beam by Macro Fiber Composite active element embedded to its surface. The numerical simulations of the system using the Finite Element Method (FEM) are performed. The Abaqus software package is applied. The time-domain analysis using the implicit method is carried out. The excitation of the system by concentrated load as a periodic force is defined. The beam response recorded by the sensor is used in the proportional control (P). In this application the MFC element is activated with a voltage signal, which is directly proportional to the measured displacement. A subroutine UAMP is prepared for implementation of the control algorithm. The resonance curves for the beam with and without control system are determined. Next, the experimental studies are performed and both results are compared. It was found that the proportional control algorithm of the MFC element can be used to change the stiffness of the thin-walled beam.
