Abstract
This study considers the significance of geometrical configuration on the noise cancellation performance in the three-dimensional linear propagation medium for the compact source, and proposes a Proportional Derivative - Fuzzy Logic Control (PD-like FLC) scheme for active noise control (ANC). There are two contributions 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 nonlinear problem and complex system. The second contribution is to investigate the effect of different distance ratios on cancellation performance or degree of cancellation. Matlab/Simulink bench tests are provided. The simulation results reveal that the TSK-type PD-like FLC performs better and different distance ratios result in different cancellation performance and the difference is significant. The optimal degree of cancellation can be achieved if both transducers placed close to the secondary source.
