利用MSP430产生SPWM波，对永磁同步电机进行变频控制(SPWM PMSM conctrl)

说明：  无线网络路由算法，直接传输到基站，可以在MATLAB上运行。(Wireless network routing algorithms, directly to the base station transmission, can run in MATLAB. )

matlab vide the examined window into cells (e.g. 16x16 pixels for each cell). For each pixel in a cell, compare the pixel to each of its 8 neighbors (on its left-top, left-middle, left-bottom, right-top, etc.). Follow the pixels along a circle, i.e. clockwise or counter-clockwise. Where the center pixel s value is greater than the neighbor s value, write 1 . Otherwise, write 0 . This gives an 8-digit binary number (which is usually converted to decimal for convenie

说明：  压缩感知Basis Pursuit基追踪算法，稀疏度和正确率的关系以及采样率和正确率的关系(Basis Pursuit based on compressed sensing and tracking relationships between sampling rate and accuracy of the algorithm, and the correct rate of sparsity)

利用MATLAB实现变长自适应滤波，实现语音增强的功能(MATLAB realize the use of variable length adaptive filtering, realize the function of speech enhancement)

说明：  LMS (Least Mean Squares): most basic canonical ANC algo FxLMS (Filtered eXtended Least Mean Squares): adds an additional learned filter for the secondary path signal - signal from cancellation speakers to users ears - to account for phase problems and audio coloration added during practical noise cancellation applications NLMS (Normalized Least Mean Squares): adds simple adaptively updated learning rate on top of LMS to speed convergence. FxNLMS (Normalized Filtered eXtended Least Mean Squares): combines FxLMS and NLMS FuNLMS (Filtered-u Last Mean Squares): adds an additional active LMS filter to FxNLMS to cancel out noise bleeding from the cancellation speaker to the error mic. Fairly robust but convergence not gaurunteed!

基于matlab/simulink的直流无刷电机的仿真。(Based on matlab/simulink simulation of DC brushless motors.)

说明：  PV太阳能光伏电池的IV曲线的设计与仿真(PV IV)

说明：  具有动态优化功能，能实现在线预测功能，在预测控制领域有较强的实用价值(Dynamic optimization, online prediction function can be realized in the field of predictive control has a strong practical value)
