说明：  人脸区域检测，对图像中的人脸区域进行检测并用矩形框标记。(Face region detection, face image in the region to detect and mark with a rectangular box.)

短时傅里叶变换的例子，matlab语言,简洁实用(shot time Fourier transform using matlab)

包括随机梯度算法，相对梯度算法，DC-DC部分采用定功率单环控制，调试通过可以使用，快速扩展随机生成树算法，基于chebyshev的水声信号分析，IMC-PID是利用内模控制原理来对PID参数进行计算，有PMUSIC 校正前和校正后的比较。( Including stochastic gradient algorithm, the relative gradient algorithm, DC-DC power single-part set-loop control, Debugging can be used, Rapid expansion of random spanning tree algorithm, Based chebyshev underwater acoustic signal analysis, The IMC- PID is using the internal model control principle for PID parameters is calculated, A relatively before correction and after correction PMUSIC.)

自己建立的iclark变换模块，根据TI公司永磁电动机例程编写(iclark tansform created by myself, based on TI s permanent magnet motor routines)

An effective undergraduate controls curriculum will have strongly coupled laboratory and classroom components. It is important that the students experience the application of the classroom theory. Mathwork’s Simulink environment is ideal for teaching modeling and simulation of feedback control systems
