代码说明:

灰色图像在matlab中以矩阵形式存在,灰度级为k的话,矩阵元素大小为0——2的k次方-1,为了减小视觉的分辨不清图像的缺陷,想到对灰色图像进行彩色处理,这就叫做灰度图像的伪彩色处理,而伪彩色处理经常用的三种方法是灰度级分割、灰度级——彩色变换、频域变换法

    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):
