The life of an engineering structure in each industry is a major factor for maintenance of
equipment. The structure can be a beam, plate, shell, panel, or truss. The life of engineering
structures reduces due to vibration amplitude or the design for mechanical system can be far
from the goals of designers. In this study, a cantilever beam, which is turbulent based on
Timoshenko theory modeling and under external flexural force, simulates. In order to obtain
displacement of the beam, piezoelectric sensor is installed as a patch at bottom of the structure
and sends the incoming signal to the fuzzy controller. This controller is optimized based on
single objective genetic algorithm (GA). Then, the best signal is sent from controller to
piezoelectric actuator at the top and at the exact coordinate where the sensor is installed and
completes the control loop for vibration attenuation.
