利用自抗扰控制器理论，提出了一种新颖的永磁同步电动机无位置传感器矢量控制系统 的转速估计方法。(A novel speed estimation approach to sensorless vector control of Permanent Magnet Synchronous Motor (PMSM) based on Active Disturbance Rejection Controller (ADRC) was proposed. )

关于matlab 的信号产生器的源码，希望对大家有用，这是我们的实验内容，绝对是一手资料(On the signal generator matlab source code, useful for all of us hope that this is the content of our experiments, it is first-hand information)

说明：  基于泰勒级数的灰度预测，这个里面的好多东西都写成了函数(Taylor series based on the gray prediction, the inside of a lot of things written in the function)

进行雷达测速的频谱分析，主要是对实际信号分析得到多普勒频率，进而求出车运行的速度(Spectrum analysis of radar speed。The Doppler frequency of the actual signal analysis, and then calculate the running speed of the car)

ANALYSIS OF TUMOUR GROWTH MODEL IN MATLAB

LMS自适应滤波算法实现信道均衡，估计逆系统(LMS adaptive channel equalization filter algorithm, it is estimated inverse system)

Character recognization

说明：  余成波《数字图像处理及Matlab实现》,对学习用matlab做图像处理有很大帮助(digital image processing,use matlab)

该算法把计算出的图像不变质心作为对其进行对数极坐标变换的原 点, 再作傅立叶变换, 取出中频段幅值作为水印嵌入域。该算法具有较好的鲁棒性、可检测性, 能同时抵抗几何攻击和信号 处理攻击, 它在数字图像的版权保护等领域有广泛的应用前景。(The algorithm to calculate the heart of the image does not degenerate as the number of its polar transformation of the origin, further Fourier transform, remove the watermark embedding in the frequency domain as amplitude. The algorithm has better robustness, detectability, can also resist geometric attacks and signal processing attacks, which in the digital image copyright protection and other fields have a wide range of applications.)
