annihilation or reduction of each kind of noise blended in correct data signals is a field that has attracted many researchers. it is a fact that fuzzy theory presents full capability in this field. fuzzy filters are often strong in smoothing corrupted signals, whereas they have simple structures. in this paper, a new powerful yet simple fuzzy procedure is introduced for sharpness reduction in ...

The Digital notch filter and Digital comb filter most useful in eliminating annoying frequency components. In this paper the cost analysis and resource analysis of both the filters has been done with different interpolation factor. The low pass filter is used to recover original signal from its samples. This is also known as interpolation filter. The result shows that Comb filter provides an 85...

Power generation from Renewable Energy Sources (RESs) is unpredictable due to climate or weather changes. Therefore, more control strategies are required maintain the proper power supply in entire microgrid. This paper presents a simulation scheme utilizing solar system instanced by Photovoltaic (PV) panels coupled grid, loads, and an energy storage device. At first, modeling PV cell their oper...

In recent years, active filters have been considered and developed for elimation of harmonics in power networks. Comparing with passive, they are smaller and have better compensating characteristics and resistance to line distortions. In this paper, a novel idea based on adaptive filter theory in presented to develop an active filter to eliminate the distortions of an arbitrary signal. Using th...

The composite material flywheel rotor of a energy storage system (FESS) has low natural frequency. When the suffers from noise interference, magnetic bearing generates force with same frequency as and causes vibration to occur. Thus, it is necessary suppress suspended (MS) FESS. LMS adaptive notch filter generally adopted for suppression. suppression performance different when insertion positio...
