This paper gives a description of a robust active noise control design procedure. Here, the weighting matrices Q and R are optimized to meet the robust performance and robust stability requirements of the active noise system. The experimental validation of the method has shown that the noise reduction is significantly improved. Moreover, if an estimation of the uncertainty is known, a robust design can be performed. This robust design provides a smaller variation of the noise reduction and guaranties the stability of the system. The worst-case performance of the robust design can be higher than the worst-case performance of the nominal design. These findings suggest that individual weighting parameters for each transducer and frequency may be a promising method to improve the active noise control performance. Moreover, the consideration of the uncertainties is a further significant step towards an industrial application.
