A Study on PD-like Fuzzy Logic Control Based Active Noise Control for Narrowband Noise Cancellation with Acoustic Feedback and Distance Ratio

Abstract

This study considers the significance of geometrical configuration on the point noise cancellation in the three-dimensional linear propagation medium as its background field and proposes a Proportional Derivative—Fuzzy Logic Control (PD-like FLC) scheme for active noise cancellation (ANC). There are two motivations/aims of this study. The first one is to make a comparison between two types of FLC, Mamdani-type and Takagi, Sugeno and Kang (TSK)-type as Mamdani-type is the most common choice for PD-like FLC and TSK-type works better with the nonlinear problem and complex system. The second motivation is to explore the effect of different distance ratios on the degree of cancellation. Matlab/Simulink bench tests are provided. The simulation results reveal that the TSK-type PD-like FLC performs better and the effects of different distance ratios on the degree of cancellation is significant while the optimal configuration is to place both transducers close to the secondary source.
