案例为运用最优控制理论，实现对吊车数控系统的仿真。运用matlab仿真实现。(Case for the use of optimal control theory, to achieve the crane CNC system simulation. Use matlab simulation.)

说明：  利用双线性变换法设计一个级联型的椭圆IIR滤波器，对一段含噪语音信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。本课程设计仿真平台为MATLAB7.0，开发工具是M语言编程。首先在Windows下用录音机工具录制一段语音信号，并人为加入一单频噪声，然后对信号进行频谱分析以确定所加噪声频率，并设计滤波器进行滤波去噪处理，最后比较滤波前后的波形和频谱并进行分析。(Bilinear transformation method is used to design a cascade elliptic IIR filter, for a period of noise speech signal filtering denoising processing and according to the waveform and spectrum analysis of filtering performance before and after filtering. This course design simulation platform for the MATLAB7.0, development tools is M language programming. First under Windows tool to record a voice signal, a tape recorder and deliberately added a single frequency noise, and then the signal to determine the added noise frequency spectrum analysis, and design the filter for filtering denoising processing, finally compared before and after the waveform and spectrum of filtering and analyzed. )

变压器故障诊断三比值法，可以调节比值范围(IEC threerate)

说明：  最大类间方差算法可以有效地进行相应的图像分割(Otsu algorithm can make the appropriate image segmentation)

基于matlab的工具箱，应用模糊控制系统方法设计实现PID控制。(Based on Matlab toolbox, the application of fuzzy control system design method achieves the PID control.)

PCA-SIFT算法中用于训练矩阵的程序(training matrix in PCA-SIFT)

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several correction factors for other propagation conditions, such as: Antenna height and carrier frequency Suburban, quasi-open space, open space, or hilly terrain areas Diffraction loss due to mountains Sea or lake areas Road slope Hata derived empirical formulas for the median path loss (L50) to fit Okumura curves.

用减谱法进行语音增强，效果还不错。 读入语音，调整噪声水平即可。(Spectral method used by speech enhancement, the effect was not bad. Read into the voice, the noise level can be adjusted.)

Summary: The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file. MATLAB Release: R12 Description: MPEG is an ISO standard movie encoding format. The MPEG converter for MATLAB takes a MATLAB movie matrix and writes the movie to disk as an MPEG file with file extension .mpg (MPGWRITE). It also takes an MPEG file and converts it into a MATLAB movie matrix (MPGREAD). (Summary: The MPEG converter takes a MATLAB movie matrix and writes the movie to disk as an MPEG file.
