Active Vibration Control of Piezoelectric Material Using Fuzzy Logic Controller

Active control of vibration has been the subject of a lot of research in recent years. This study presents a fuzzy logic controller (FLC) to minimize structural vibration using collocated piezoelectric actuator/sensor pairs. The proposed fuzzy controller increases the damping of the structures to minimize certain responses. The PID controller is used as a contrast controller to the FLC. The numerical simulation results show that the fuzzy approach is much portable than PID method. In summary, a novel vibration absorption scheme using fuzzy logic has been demonstrated to significantly enhance the performance of a flexible structure with resonant response.
