Active Noise Control in Pardis Coach using Different Fuzzy Controllers

In recent years, need to increase the convenience of trips in railway vehicles causes that train operators and manufacturers focus on reducing the noise level which is sensed by passengers. In this paper, first the state of modeling acoustic noise in cab train is discussed and natural frequencies and acoustic mode shapes are derived and then formulation of acoustic pressure in the cab will be o...

Modified FxAFA Algorithm Using Dynamic Step Size for Active Noise Control Systems

In this paper, a modification in the existing FxAFA algorithm by varying step size dynamically is proposed. The introduction of a dynamically varying parameter at the denominator of the step size, improves the convergence rate of the system. This new step size is calculated for every value of the error signal. The proposed algorithm gives faster convergence as compared to that of FxAFA algorithm.

A Hybrid Data Clustering Algorithm Using Modified Krill Herd Algorithm and K-MEANS

Data clustering is the process of partitioning a set of data objects into meaning clusters or groups. Due to the vast usage of clustering algorithms in many fields, a lot of research is still going on to find the best and efficient clustering algorithm. K-means is simple and easy to implement, but it suffers from initialization of cluster center and hence trapped in local optimum. In this paper...

Active Noise Cancellation using Online Wavelet Based Control System: Numerical and Experimental Study

Reaction wheels (RWs) used for attitude control of space vehicle systems usually encounter with undesired wide band noises. These noises which significantly affect the performance of regulator controller must tune the review or review rate of RWs. According to wide frequency band of noises in RWs the common approaches of noise cancellation cannot conveniently reduce the effects of the noise. Th...

An Efficient Algorithm for Active Noise Control

Active noise control (ANC) systems have been increasingly researched and developed [1]. The use of the modified filtered-x structure for ANC using finite impulse response (FIR) adaptive filtering [2] will be assumed in the rest of this paper (Fig. 1). The multichannel versions of the filtered-x least-mean-square (FX-LMS) and the modified FX-LMS (MFX-LMS) algorithms are the benchmarks to which m...
