求出laguerre滤波器的分子分母系数，绘出其幅频响应图并与FIR滤波器作比较。该程序为19阶Laguerre低通滤波器和22阶带通滤波器(obtained laguerre filter coefficient of molecular denominator, chart its amplitude frequency response plans with the FIR filter for comparison. The procedure for the 19-Laguerre low-pass filter and 22 band pass filter)

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):
