Abstract
This paper deals with active noise control (ANC) in an enclosure on a broadband frequency range. It aims to compare two control strategies: (i) an adaptive control approach namely FxLMS control, (ii) a robust H∞ control, in the SISO (single input single output) case. Only feedback scheme is considered and disturbance sources are assumed to be unknown. For the aim of a fair comparison focusing on the same frequency range of attenuation, a new FxLMS algorithm with a weighting filter is proposed. Finally, achievable performances of each control are analyzed through simulation and experimental results driven on an instrumented setup.
