dc.description.abstractThis paper reports the experimental results in the application of feedback control of acoustic noise in a 2D duct. It is shown that the feedback control of 2D ducts poses peculiar problems compared to simple 1D ducts. The chief amongst them are the need for explicit budgeting of uncertainties and dealing with high model orders. This paper demostrates a practical way to design controllers for such systems using minimax LQG methods. It is shown that an important step in the controller design is the proper choice of a weighting function. The results presented in this paper are impressive and they can be further improved by proper choice of actuator and sensor placements.en
