代码说明:

说明:  一个用于求圆周率pi的matlab算法。题目背景:取一长面积为1平方米的正方形白纸,在白纸的内部画一个直径为1米的圆,如下图所示。此圆恰好与正方形的四条边分别切于一点,它的面积是 pi*(1/2)^2 =pi/4 ,然后,你可以抓一大把芝麻,一粒一粒地随便地扔到白纸上。在你扔麦子的过程中可以请一位朋友帮助记录:一共扔了几次?有几次是扔在圆里面? 实验结束后,你只须用“芝麻落在圆里的次数”除以“一共扔的次数”得到的结果就是圆的面积。则pi就是“圆的面积*4”了 当然,你扔的次数越多,结果就越精确!()

    说明:  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):
