In this paper, a neural network based reference current computation method for active power filter (APF) control under non-ideal mains voltage with different load condition is proposed. The neural network controller has been designed to extract fundamental frequency components from non-sinusoidal and unbalanced currents. These fundamental frequency components will be used as unit templates. The APF...
This paper presents a new technique for harmonic detection, estimation and elimination in power system. The approach expresses the input signal in the form of Fourier Transformation and adjusts the Fourier coefficients using Linear Adaptive Filters (Adaline). Two of the existing approaches using conventional Fast Fourier transformation (FFT) and FFT with modified W-H learning have been discussed with...
In this paper, a neural network model is proposed which can be used for designing any monopole antenna whose element is square shaped and required to exhibit a wide band characteristics. All the antennas designed using this model shows a wideband response between 4.5 GHz - 5 GHz. This model is prepared using Feed Forward Back Propagation Algorithm. The results given by the prepared model are compared...
