伺服电机控制系统，02年开始积累，效果好，速度快，PI控制，经典控制，fuzzy PID，自适应控制，速度位置控制等等，欢迎大家参考。(Servo motor control system, in 2002 began to accumulate, effective, fast, PI control, classical control, fuzzy PID, adaptive control, speed position control, etc., we welcome the reference.)

数字滤波器设计实例，里面包含VERILOG语言和MATLAB语言写的代码。(Digital filter design example, which contains the VERILOG language and MATLAB language to write code.)

利用模糊PI控制器对空调室温对象进行控制，给出具体的室温模型及其对应的控制代码。(fuzzy PI controller targets for air-conditioning control room temperature, give a specific room temperature model and the corresponding control code.)

小波神经网络的训练和预测，隐含层采用morlet小波基函数，包含简单的函数拟合算例。(Training and prediction of wavelet neural network. Hidden layer uses morlet wavelet function with a simple example.)

说明：  稀疏傅立叶算法，matlab实现仿真，并对SFFT和FFT算法对同一数据的处理时间进行了对比。(Sparse Fourier algorithm, matlab to achieve the simulation, and the SFFT and FFT algorithm for the same data processing time were compared.)

QPSO和FDTD相结合的英文文章，费了好大劲找到的(FDTD combined QPSO and English articles, and with great enthusiasm to find)

本文算法是将24 位真彩图的亮度分量分块 DCT ,然后利用DCT 量化系数的奇偶特性嵌入8 位灰度水印图,并通过PN 序列加密来保证水印的 安全性。算法中,将灰度图像转换为二进制数据 流,置乱后扩频调制,隐藏在宿主DCT 系数量化值 中,提取时不需要宿主信号,实现水印信号的盲提 取。(This algorithm is 24-bit true color pictures of the luminance component of block DCT, quantization DCT coefficients and then use the parity properties of 8-bit grayscale watermark embedding map, and through the PN sequence of encryption to ensure the security of the watermark. Algorithm, the gray image into binary data stream, scrambling after the spread spectrum modulation, hidden in the host DCT coefficient quantization values, the extraction does not require the host signal, the blind watermark extraction.)

说明：  主成分分析算法，有大量数据，初学者可以根据数据看程序，并且可以出现图像(Principal component analysis algorithm, there is a large amount of data, beginners can look at program according to the data, and can appear the image)
