Fuzzy active control of a distributed broadband noise source

摘要

This paper describes the use of fuzzy logic for the active control of a distributed broadband noise source modelled by multiple primary sources with low correlation between them. The early signals are collected from several early microphones placed near the sources. In addition to its ease of implementation and to making explicit the heuristic rules of control, the fuzzy logic approach localizes the control for each early microphone/loudspeaker pair, making it work as an independent unit. The use of several, independent central units offers improved computational efficiency, which is critical for situations when the source is non-stationary, and offers the potential for parallelization.
