Abstract
This paper describes the study of active noise control schemes using t wo-degree-of-freedom control based on model matching for a one-dimensi onal exhaust duct. In this study, at first, the models are identified using measured frequency responses. Then the feedback controller is de signed by using H-infinity control theory and the feedforward controll er is designed by using model matching theory. Simulations and experim ents are carried out using the designed controllers. The experimental results show a good agreement with the simulation results, and noise r eduction of more than 15 dB is obtained over the frequency range from 100 Hz to 500 Hz at the microphone location.
