数据包络的程序，解决多目标决策，程序中有部分正文的注释，很适合初学者使用。(DEA procedure to solve multi-objective decision-making, program notes, some text, it is suitable for beginners.)

基于混沌理论的图像解密算法，希望对研究图像加密解密的人员有帮助。(Based on chaos image decryption algorithm ,i hope it will be helpful. )

使用matlab实现OFDM系统功能并仿真验证其功能 (Use matlab to realize the OFDM system simulation)

说明：  双馈感应电机的矢量控制仿真模型，用的是定子磁链定向(The vector control simulation model of doubly fed induction motor uses stator flux orientation)

说明：  混凝土结构弯矩曲率，适用于各种混凝土，包括纤维混凝土(Moment curvature of concrete structure)

谱分析的源程序，适合通信等专业的初学者学习使用，希望给需要的人帮助(Spectral analysis of the source, suitable for beginners to learn communication and other professional use, I hope to those who need help)

DC Motor Thermal Circuit The demo illustrates how the thermal behavior of a motor can be simulated in lumped parameters.

This project consists of two back to back pwm converters used for simulation of traction load in normal operating mode. The first side is connected to a single phase network and uses hysteresis current control. The second side is connected to a three phase network and uses space vector modulation for controlling its inverter.

说明：  it is to rotat the imag n reg it

输入信号为方波信号+高斯白噪声，方波信号基 频为1kHz，幅值为1，高斯白噪声方差为0.2， 均值为0，采样频率为20kHz。试用周期图法和 ARMA谱估计法(SVD-TLS)估计此信号的功率 谱，并分析比较其结果(The input signal is a square wave signal+ Gaussian white noise, square wave signal fundamental frequency 1kHz, amplitude is a Gaussian white noise variance is 0.2, the mean is 0, the sampling frequency is 20kHz. Try periodogram and ARMA spectral estimation method (SVD-TLS) estimate the power spectrum of this signal, and the analysis and comparison of the results)
