MORENO-GARCIA, Francisco Ernesto; BECERRA-VARGAS, José Armando  e  CARDENAS-CONTRERAS, Edwin Martín. Implementation of a Fuzzy Adoptive Strategy for Active Vibration Control of Beams. Rev. Fac. ing. [online]. 2014, vol.23, n.36, pp.56-64. ISSN 0121-1129.

This paper proposes an active control of vibrations in a mechanical system type beam cantilever using a Fuzzy controller implemented in LabVIEW. In the step of measuring a capacitive accelerometer is used to detect the displacement introduced in the structure due to a force generated by the impactor instrumented with piezoresistive sensor. For computational implementation is used LabVIEW software operating in conjunction with a DAQ 6009 acquisition card data. For actuation system are located in the sheet bar of piezoelectric material which has the function to attenuate the present vibration through the generation of opposing forces. The experimental results are presented with the objective of to gain experience and demonstrate the efficacy of the active control of vibrations using piezoelectric actuators.
