《有限单元法教学实习程序汇编》内容简介
汇编了四个有限单元法程序（平面刚架计算程序FEM2.FOR、平面三结点三角形单元计算程序FEM3.FOR、平面四结点等参数单元计算程序FEM4.FOR和空间八结点等参数单元计算程序FEM8.FOR）。其中FEM2.DAT、FEM3.DAT、FEM4.DAT和FEM8.DAT为四个算例的输入数据文件。为了便于读者读懂程序，对每个程序做了详细注解。(A compilation of four finite element method program (plane frame calculation program FEM2.FOR, flat three node triangular element calculation program FEM3.FOR, flat four nodes and other parameters and space unit calculation program FEM4.FOR eight nodes, etc. parameter unit calculation program FEM8.FOR). Which FEM2.DAT, FEM3.DAT, FEM4.DAT and FEM8.DAT four examples of input data files. To help readers understand the program, for each program in detail annotations.)

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):
