Laypunov 指数计算，用于判断系统的定性及稳定性分析(The index of Laypunov calculation used to determine the qualitative and stability analysis of)

IEEE39节点动态系统参数，其中各节点的数据准确性都经过校验检查。(IEEE39 node dynamic system parameters, data accuracy check each node have been checked.)

说明：  该code读出naca4412.txt中基本balde坐标，在读取data1.txt中设计要求，生成FinalCoordinates.txt文件，包含所有生成balde airfoil所需coordinates。(this matlab code read the blade coordinates in naca4412.txt, and then read the design requirements in data1.txt. Finally, it will generate the FinlCoordinates.txt which include all the coordinates of blade airfoil.)

主要内容(signal_analyzer.rar)如下： 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。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)
