Active vibration suppression in a flexible cantilever beam using fuzzy logic controllers

This paper presents a novel control system to find suitable solution for addressing the vibration problems in fixed-free cantilever beam system structures. The solution n is generated using fuzzy logic controller (FLC) utilizing single and multiple control actuators. The fuzzy controller employs the error (between a reference model output and the cantilever response) and error change to generate the control input increment in order to preserve the desired reference model performance. The controller is tested within a simulation environment. Results show that an excellent control performance is possible. (author). 14 refs. 3 tab., 15 figs
