说明：  人工神经网络在数模混合电路故障诊断中的应用(Artificial Neural Networks in mixed digital-analog circuit fault diagnosis)

该程序是一个振荡相位噪声模型。相位噪声是衡量频率标准源(高稳晶振、原子频标等)频稳质量的重要指标，随着频标源性能的不断改善，相应噪声量值越来越小，因而对相位噪声谱的测量要求也越来越高。(The program is a model of phase noise oscillator. Phase noise is a measure of frequency standard source (high stability crystal oscillator, atomic frequency standard, etc.) an important indicator of the quality of the frequency stability, with the frequency standard source performance continues to improve, the corresponding noise value smaller, and thus the phase noise spectrum of the measurement requirements higher and higher.)

个人找的一个电子书，主要介绍matlab的入门知识，讲解很详细，有例证，个人觉得很好用！(Books about matlab！)

兔子繁殖问题，好累啊 重要的是画出曲线，而不是柱状图(Rabbit breeding problems, tired. what important is to draw the curve, rather than the histogram)

协同PSO算法是运用协同组合方法，采用K均值来分类，PSO辅助来实现聚类分析(PSO algorithm is the use of collaborative synergistic combination of methods, the use of K-means to classify, PSO assisted to achieve clustering analysis)

pwm整流器的建模仿真以及可以实现双闭环控制，并已经验证可以成功(controllable PWM Rectifier pwm rectifier modeling and simulation can achieve double-loop control, and validation can)

模糊PID 调试成功 先运行fuzzypid.m,在运行fuzzypiduse.m(Fuzzy PID successful commissioning of power function and simulink simulation)

根据已给ecg数据文件，画出心电图波形，并自动标记出特征点位置，并计算P-R时间间隔 等参数。 附件是.dat为数据文件，为二进制文件，每2个字节代表一个采样点，采样频率1000hz。依 次为1-12导联的第一个采样点，其次是1-12导联第二个采样点，.... .hea头文件是文本格式说明文件，可以看到十二导联存放的先后顺序。 (According to the data file has to ecg, draw the ECG waveform, and automatically mark the feature points, and calculate parameters such as PR interval. The attachment is. Dat for data files, binary files, each 2 bytes represent a sampling point, the sampling frequency 1000hz. Followed by a 1-12 lead in the first sampling point, followed by 1-12 second sampling point lead ,..... Hea header file is a text file format that you can see the sequence)

基于matlab工作平台的使用ITD法进行模态参数识别，程序中使用最小二乘法进行减缩计算。(a method of modal parameter identification)
