BladedDLLInterface
This source file contains example PitchCntrl(), UserHSSBr(),
! UserVSCont(), and UserYawCont() routines that are used to interface
! FAST with a master controller implemented as a dynamic-link-library
! (DLL) in the style of Garrad Hassan s Bladed wind turbine software
! package. All four routines call routine BladedDLLInterface(), which
! contains a call to the Bladed-style DLL that evaluates as DISCON().
! Routine BladedDLLInterface() USEs a MODULE named
! BladedDLLParameters(), which stores values of PARAMETER constants
! used in the interface.

test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。
signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as the system output signal. signal_analyzer.m first test1.txt data read workspace, and then proceed to FFT, analysis of the two signals in the frequency, the output for input amplitude attenuation (db), the output of the input phase difference.)

MYFEM
有限元求解柏松方程。本文采用FORTRAN语言编制程序。程序中大部分变量采用有名公共区存储方式存储，这样可以减少内存占用量。
IFG：生成有限元网格信息，即元素节点局部编码与总体编码对照表，节点实际坐标，边界节点编码与边界点上的已知值
GKD：生成总刚一维存储对角元的地址，计算总刚一维存储长度
FIXP：设置已知节点函数值
GK(NI,NJ,ADJ,AIJ)：单元刚度矩阵计算
GF(NI,N,M,LE,YI,FE)：单元列阵的计算
AK(I,J,AIJ)：总刚度矩阵元素迭加
QEB：总刚度矩阵和总列阵合成
BDE：边界条件处理
SOLGS：Gauss-Seidel迭代法求解方程组
UDIFF(NI,NFLAG,UDIF,LE,ADJ)：标准元素内形状函数导数计算
DIFF：节点上 ， 加权平均
(In this program, FEM was used to solve the possion equation. It is implemented through FORTRAN)
