Abstract
Good disturbance attenuation levels comparable to those obtainable with adaptive control schemes can be achieved in an active noise control (ANC) system with the linear time invariant (LTI) control design approach. The design approach blends H∞ synthesis and Quantitative Feedback Theory (QFT) design of feedforward and feedback controllers. An initial H∞ design is performed on the nominal identified model with uncertainty due to identification error. The H∞ controller is tuned in the QFT environment using experimental duct frequency response in order to improve performance and to minimize control bandwidth. Design trade-offs are considered between the feedforward and feedback controllers that are transparent within the QFT environment.
