Evaluation of the Performance of an Active Noise Control System in an Aircraft Mock-up
Responsible organisation
2000 (English)Conference paper, (Refereed) Published
Abstract [en]

This paper treats the convergence behavior and robustness of a narrowband twin-reference feedforward active control system using different kinds of actuators and control sensors, and various actuator/sensor configurations. Results from a practical experiment carried out in a fuselage section of a SAAB 340 aircraft, using beating and non-beating sound fields, are presented. The results show that the proposed multiple-reference controller based on the actuator-individual normalizedjfiltered-x LMS algorithm exhibits high performance with respect to robustness and noise suppression, for the different configurations as well as for beating and non-beating sound fields. A slight degradation of the performance was noticed for beating sound fields.
