Objectives

This project applied robust control techniques for the attenuation of mechanical disturbances, including noise and vibrations.

The main conclusions of the project are:

  • Classical control algorithms (FXLMS, FULMS) are effective but face challenges when noise is rich in frequency components.
  • Attenuation of the acoustic field by interference with a secondary acoustic field has significant limitations. It is preferable to act directly on the source to reduce the amplitude of the primary acoustic field (i.e., reducing the primary source emission).
  • Combining passive and active techniques offers greater benefits than applying them separately.

Participating Entities: Polytechnic University of Catalonia.

Departments: Systems Engineering, Automatic Control and Industrial Informatics (ESAII), Electronic Engineering (EE), Optics and Optometry (OO), and Mechanical Engineering (EM).
