The impact hammer test is performed on the glass-epoxy cantilever beam at different temperatures. Experimentally recorded impact hammer force signals and piezoelectric accelerometer time-domain signals are processed through a system identification toolbox in MATLAB to obtain transfer functions of the plant models. A robust fuzzy logic controller is developed to accomplish the effective vibration control of a cantilever composite beam operating at different temperatures. The fuzzy logic controller with two inputs and one output is designed using the 20 if-then rules. The results are presented in both frequency and time domain, keeping the vibration attenuation of the fundamental frequency as the point of interest. The results indicate the proposed fuzzy logic control strategy can attenuate the vibrations of a cantilever composite beam for a wide temperature range. © The Author(s) 2022.Cantilever beamsComposite beams and girdersComputer circuitsControllersFuzzy logicHammersLaminatingNanocantileversTime domain analysisVibration controlCantilever composite beamsComposite cantilever beamsEffects of temperatureExperimental techniquesFree-vibration testsFuzzy logic controllersImpact hammer testsLaminated composite beamNumerical techniquesThermal environmentLaminated composites
