Abstract

This paper investigates the performance of robust control for broadband disturbance using acoustic pressure minimization over space and frequency. The theory and simulations of the acoustic pressure minimisation using H2 control for two-channel and three-channel systems are presented. Constrained minimisation of the pressure is introduced, to achieve control over the pressure in both space and frequency. The results show that good attenuation is achieved at the desired range over space and frequency using a two-channel system. However better performance could be achieved using a three-channel system. The shape and the location of the attenuation area could also be controlled using a three-channel system. The work presented in this paper is the first part of the study and only concerns a plane wave primary field with two and three secondary sources for simplicity. In the next part of the study a more realistic sound field like a diffuse field will be investigated and some experiments will also be carried out.
