摘要

研究了窄带噪声的主动控制问题。结果表明，先前提出的基于l2范数性能度量最小化的反馈控制算法SONIC(自优化窄带干扰抵消)可以使用Li方法重新导出。所得到的鲁棒SONIC算法对重尾测量噪声(如非稳态噪声)的鲁棒性优于原SONIC算法。

Robust algorithm for active feedback control of narrowband noise

The problem of active control of narrowband acoustic noise is considered. It is shown that the proposed earlier feedback control algorithm called SONIC (self-optimizing narrowband interference canceller), based on minimization of the L2-norm performance measure, can be re-derived using the Li approach. The resulting robust SONIC algorithm is more robust to heavy-tailed measurement noise, such as the a-stable noise, than the original SONIC.
