EXPERIMENTAL STUDY ON ACTIVE VIBRATION CONTROL OF A PIEZO-BEAM STRUCTURE WITH FUZZY LOGIC CONTROLLER

In this study, it has been shown that active vibration control of the beam can be provided using the fuzzy logic controller. The test setup consists of a cantilever beam which illustrates a wing of airplane or a blade of helicopter, piezoelectric patches pasted on both sides near the fixed end in order to make the beam smart. This piezo-beam system is intended to be suppressed a disturbing signal at the first resonance frequency by the controller signal. As a controller, fuzzy logic controller is preferred instead of conventional ones. It is shown through the simulated and the experimental result that the vibration given to the system has been damped with fuzzy logic controllers developed by taking advantage of experience and references
