Diseño e Implementación de un Sistema de Control Activo de Ruido Acústico de Baja Frecuencia para Compresor Neumático Marshal Inductive Motor 931373.

Abstract

Noise pollution is a problem that has been increasing in the industrial sector, thus have made advances in techniques to help their mitigation and control. Although passive methods have been developed for this purpose, their effective use not cover the entire spectrum of noise, because low frequencies its implementation should be with massive structures usually not fully comply with this function, which have been developed new methods, such as active noise control. Active noise control is the attenuation of noise by overlapping opposite phase pressure waves generated by the noise source and a controller; this technique dates back to the 30s when Paul Lueg patented schemes in which the active noise control is based. This idea has been around for decades in permanent transition phase between the acoustic concept, laboratory experimentation and the transition between the laboratory and the development of systems applicable trade control at any stage of noise cancellation. Currently, these systems have become more important due to technological advances that allow it a few years ago could only be in a theoretical context. The requirement of the problem requires computationally enough resources to run a reliable solution. In this project this issue was addressed and continued with the research of techniques to control and reduce external noise to which a worker is exposed during their work activity, either from the machine operates, or the environment that surrounds. Taking advantage of advances in digital signal processors (DSP) active control of low frequency acoustic noise in the air compressor Marshal inductive motor 931373, which is a noise source often used in the mechanical sector will apply, seeking to optimize active control systems and the management of acoustic principles of these, representing, ultimately, the success of the project.
