Abstract:

The smaller size and the performance in the low frequency range make active noise control systems an attractive upgrade of purely passive means. As an alternative to the popular adaptive schemes, some controllers designed with robust control tools have been proposed. The appeal of a robust design are the more rigorous stability results. In the work presented here, first some inherent limitations of the traditional robust approach are given. Then a robust, wave-based controller structure is suggested, which overcomes these problems and is, moreover, robust to changes in the plant structure. The controller is implemented on a laboratory duct system. Its robustness is validated by a series of experiments on different plant set-ups.
