Active Noise Control Proposal for Rotating Machines
Jesús A. Calderón, Julio C. Tafur, Eliseo B. Barriga, John H. Lozano
Rotating machines are absolutely used in many engineering tasks, such as “Energy transmission” given by compressors, turbines, pumps. However, these machines produce high decibels of noise, for this reason is necessary to attenuate noise by many mechanisms as passive criterion, but that can not get good response under low frequencies domain or under disturbances.
Therefore, in this research is proposed an active mechanism supported by “Least Mean Square” (LMS) strategies to get noise attenuation in 3-dimension space, furthermore a “Vibration Control Analysis” by sensors based in nanostructures.
