Experimental Model for Active Vibration Control on Lattice Structure

Abstract

Experimental activities are necessary parts of scientific work in active vibration control to investigate functionality and quality of the designed control algorithm. Current research is motivated on the usage of smart materials and novel control approaches. This study is focused on the presentation of the laboratory test model, designed for the experiments with active vibration control on the beam structure. The structure is connected to the moving platform and equipped with piezoelectric actuator, which is placed in one main leg of this construction, and with piezoelectric accelerometer, which senses the acceleration of the top of this assembly. Electrodynamic shaker is also a part of the device. It is connected to the moving platform and excites the whole structure. In the paper, there is also a part dedicated to the identification procedure of the laboratory model as well as the creation of corresponding mathematical model. At the end, the control algorithm is presented and evaluated in the simulation and on the real structure.
