说明: 出一种新
的SVPWM 算法。采用SPWM 中调制波与载波相比较的规则采样思路,通过在静止坐标系下直接
计算每个参考电压矢量所对应的三相调制波的函数值,进而得到每相电压在一个PWM 周期中的占空比。(A new SVPWM algorithm. SPWM modulation used in the carrier wave, compared with the rules of sampling ideas, through the static coordinate system directly calculated for each reference voltage corresponding to the three-phase vector modulation wave function, which has been in a phase voltage of each PWM cycle accounting air ratio.)

ECG
The early detection of arrhythmia is very important
for the cardiac patients. This is done by analyzing the
electrocardiogram (ECG) signals and extracting some features
from them. These features can be used in the classification of
different types of arrhythmias. In this paper, we present three
different algorithms of features extraction: Fourier transform
(FFT), Autoregressive modeling (AR), and Principal Component
Analysis (PCA). The used classifier will be Artificial Neural
Networks (ANN). We observed that the system that depends on
the PCA features give the highest accuracy. The proposed
techniques deal with the whole 3 second intervals of the training
and testing data. We reached the accuracy of 92.7083
compared to 84.4 for the reference that work on a similar
data.
