The model used for creating the reference voltage is shown in Fig. 4. First, photovoltaic output current (Ipv) and output voltage (Vpv) are passed through a first order low pass filter with a magnitude of G = 1 and a time constant of T = 0.01 seconds in order to filter out the high frequency components or harmonics from these signals as shown in Fig. 5 and Fig. 6. The filtered current and voltage signals (Ipv_F and Vpv_F) are then fed into the MPPT control block that uses the Incremental Conductance Tracking Algorithm. An algorithm that is based on the fact the slope of the PV array power curve shown in Fig. 7 is zero at the Maximum Power Point (MPP), positive on the left of the MPP, and negative on the right. The MPP can thus be tracked by comparing the instantaneous conductance (I/V) to the incremental conductance (∆ I/∆ V) [11] as in (1):

SIMULINK MODELS OF POWER SYSTEMS

利用MATLAB来实现离散傅里叶变换和离散傅里叶逆变换，N为离散傅里叶变换长度，形式为xk=IDFT（xn，N）(To achieve the discrete Fu Liye transform and discrete Fu Liye transform by using MATLAB, N as the discrete Fu Liye transform length, form xk=IDFT (xn, N))

In this paper, we describe a novel approach for reducing the power consumption and complexity of a multiband orthogonal frequency-division multiplexing (MB-OFDM) ultrawideband (UWB) system by applying ideas from pulsed UWB ystems. The approach is quite general and applicable to many other systems. Unlike the MB-OFDM system, the enhancement that we propose uses pulses with duty cycles of less than 1 as the amplitude shaping pulse of orthogonal frequency-division multiplexing (OFDM) modulation.

Utilisation des certaines critères comme les textures ,la couleur et la forme ,donc en peut associer un vecteurs de caractéristiques pour l’image qui se trouve dans notre base des données , Nous utilisons les maxima de courbure de passage a zéros contours de Curvature Scale Space (CSS) sur l’image comme un vecteur de caractéristiques , l’approche consiste a calculer l’image CSS de chaque frontière et ensuite trouver les maxima des contours CSS comme un discripteur de forme pour comparer des images , les propriétés de base da la representation CSS qui rendent presque unique pour la recherche de similarité sont les suivant  : - Il est robuste par rapport au bruit, l’échelle et l’orientation de l’objet - Il conserve les informations locales de la forme d’entrée. Chaque concavité ou convexité de la forme a ses propres correspondants contour sur l’image CSS, chaque point dans l’axe horizontal de l’image de CSS à son correspondant sur les limites réelles.
