The advanced filters require high computing power, but result in a rather moderate improvement as compared to the general EKF [2]. For model-based approaches, the accuracy of SOC estimation is directly related to the accuracy of the battery model. Battery performance is strongly influenced by ...
As a result, STFT is not appropriate for analysis of non-stationary signals or signals with fast-changing frequency like LFM signals. As an alternative to the traditional Fourier Transform, Xia et al. [2–4] proposed the widely linear model for frequency estimation in three-phase power systems...
By grouping the stand ages, it can be found that the year-round change trend of the stand LAI curve is almost the same between different stand ages. Therefore, this study concluded that the annual change trend in the LAI is not related to the age of the stand. The annual LAI extracted...
This causes uncertainty in a battery model parameter determination and may result in an unavoidable perturbation in a SOC estimation. Therefore, online battery modelling has attracted considerable research attention because it not only estimates the SOC precisely under different conditions and aging levels...
Introduction As fossil fuel reserves continue to decrease, new means of transportation that are independent of traditional fuels have to be found to meet the requirements of our daily life. Consequently, electrical vehicles (EV) have been regarded as a potential solution. In order to increase the...
When the channel length ranges from 20 cm to 40 cm, the channel characteristics curves have similar outlines, which indicates that there is not a linear relation between channel length and attenuation. The trend of the estimation channel characteristics g(f ) does agree with the measured result ...
output of the j-th neuron corresponds to the j-th value of the estimation result yj, as described by Equation (11). yj = Snj SD = n i =1 Yi exp - -(X - Xi )T 2δ (X 2 - Xi ) , i n =1 exp - -(X - Xi )T 2...
However, on the other hand, using OH concentration corresponding to aged (and thus, dispersed) plumes is likely to result in overestimation of the photochemical age. A comparison of the photochemical age estimated using Equation (1) with the duration of daylight on the days when the AERONET ...
