Abstract

A fuzzy logic controller is designed to suppress the vibrations of flexible beams. The distributed forces are used as control input. The Euler-Bernoulli beam and the Timoshenko beam are employed as simulation models. The uncertainties in the material properties of the beam are included in the PDEs describing the vibrations of the Euler-Bernoulli beam and the Timoshenko beam. The cantilever beam is subjected to a large initial displacement which results in uncotrolled vibrations. A fuzzy logic controller is designed to control these vibrations. The results show that the fuzzy logic controller is robust and adaptive and is suitable for the control of nonlinear as well as time-variant systems.
