以五相无刷直流电动机为例，通过对五相无刷直流电动机的建模与仿真，进而研究无刷直流电动机带载起动过程中的电机转速、电磁转矩和各相电流，并分析参数变化对系统性能的影响。(The five phase brushless DC motor as an example, through the modeling and Simulation of five phase brushless DC motor, and then the motor speed, electromagnetic torque and the phase current, and the influence of the parameters on the system performance were studied.)

kalman滤波，李国强，用于模态识别，先生称响应在用相应识别系统参数(kalman filtering, Li Guoqiang, for modal identification, sir, said in response to the recognition system with the corresponding parameters)

说明：  matlab 环境下编的时钟程序代码，业余爱好的(MATLAB，clock)

空间谱估计算法MUSIC算法和Capon算法的性能比较。图像有直方图和圆极化图两种(MUSIC spatial spectrum estimation algorithm and compare the performance of Capon algorithm. Image with histogram and the two circular polarization map)

BP neural netowrk regression

去趋势波动分析的开发程序，共享给大家，谢谢。(Detrended fluctuation analysis of the development process, for everyone to share, thank you.)

四轴动力模块，用一个顶模块控制，输入有：油门（20档）；指令；水平仪控制指令，4个输出口(Axis power modules, with a top module control inputs are: accelerator (20 files) instruction Level control instructions, four output ports)

B样条曲线曲面的生成与显示，用matlab实现(B-spline curve and surface generation and display, using matlab implementation)

DCT变换：变换域系数选取采用阈值编码，：阈值越小，图像恢复效果越好，但压缩效果差，一般取在5-10 即可很好的获得恢复图像信息。(DCT transform: transform domain coefficients selected using the threshold coding: the smaller the threshold value, the better the image restoration, but the compression is poor, and generally in the 5-10 to get a good recovery image information.)
