Abstract
This paper presents a novel approach for nonlinear active noise control (ANC) systems that addresses the limitations of traditional linear ANC systems, which fail to consider nonlinear factors. A nonlinear ANC system is proposed for non-stationary noise with a nonlinear secondary path using the improved filtered-s least mean square/fourth (IFSLMS/F) algorithm. This system utilizes the real-time complementary ensemble empirical modal decomposition (CEEMD) for noise decomposition, trigonometric functional expansions of the functional link artificial neural network (FLANN) filter, and adaptive weight updating. The IFSLMS/F algorithm uses the fast convergence of the variable step size algorithm to efficiently reduce error perturbation by performing power normalization on the error signal. The performance and robustness of the system have been validated by simulations and experiments.
期刊介绍：
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
