Adaptive feedback noise attenuation in the presence of plant uncertainties -A Dual Youla-Kucera approach
Résumé
This paper presents an adaptive algorithm forattenuation of tonal and narrow band noise in the case of largeuncertainties of the compensatory path. This scheme implementsthe Internal Model Principle (IMP) for canceling disturbances,combined with the Youla Kucera (YK) parametrizationwhich allows to directly tune the disturbance compensationfilter. Plant uncertainties are represented by means of the Dual-Youla-Kucera parameterization, and an overparametrization ofthe adaptive disturbance compensation filter is proposed to copewith the uncertain plant. In addition, a frequency condition hasto be satisfied by an appropriate design of the central controller.The experimental validation of the design is done on a relevantactive noise control test bench.
