... of the DSIM is advantages of the DSIM are their higher torque density, presented. In Section III a vector control of the DSIM is higher efficiency, reduced harmonic content of the DC link introduced. A PI-Fuzzy control of the DSIM is proposed in current [9]. Section IV. The simulation results and their ...

... the saturation due to the lack of effective severe conditions. If saturated, the transformer will overheat direct signal gathering of the magnetic strength or the and generate harmful harmonics to the grid. The measurement of the dynamic magnetic flux is an effective method to observe magnetic flux in transformer iron cores [13-15]. At present ...

... is also known that peak current control offers fast over-current switch protection [15]. In PFC applications, the peak or valley control inherently lead to line current harmonic distortion and several solutions for reducing this distortion have been proposed [10], [11] by biasing the reference waveform. On the other side, ...

... linear. The results obtained are recognize arm gestures with 3D motion primitives made promising, and they show that this approach is robust and invariant to rotation by spherical harmonic basis functions. appropriate for detecting such hand gestures. Furthermore, In [5] a comparison between gesture recognition based on by using this method, we ...
