A FUZZY ACTIVE VIBRATION CONTROL OF BEAM WITH PIEZOELECTRIC

This paper presents a study concerning the active vibration control of a smart cantilever beam that is excited by transverse vibrations of the structure that it is clamped to; and the clamped end of the beam is experiencing base motion. It has been used fuzzy method in the purpose of designing controller. The electromechanical equations have acquired from energy methods and with Euler-Bernoulli beam theory. In continuation, numerical results have been obtained from an aluminum beam with simulating in MATLAB software. The obtained results show that fuzzy control,in addition to considerable reducing of calculations capacity, has satisfactory function too.
