基于chirp信号和Multitone信号的频率特性测试方法研究，采用MATLAB仿真，是最新的研究成果。(Based on the chirp signal and the signal frequency characteristics Multitone testing methods study using MATLAB simulation, is the latest research results.)

说明：  图像处理：显示，直方图，尺寸变换，付式变换，滤波，输出图像(Image Processing: Display, Histogram, size change, pay-type transform, filter, output image)

该程序可以计算出混沌系统的李亚普诺夫指数，根据其大小，判断其状态(The program can calculate the Lyapunov index chaotic system, according to their size, to determine its status)

直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)

说明：  基于粒子群算法的PID参数寻优（MATLA程序）.zip(PID parameter optimization based on particle swarm optimization (matla program). Zip)

说明：  四阶累积量MUSIC算法和常规二阶MUSIC算法的性能与阵元数的关系(Fourth-order cumulant MUSIC algorithm and conventional second-order MUSIC algorithm performance and the relationship between the number of array elements)
