这个一个很完整的SNR的总结，里面包含各种有关SNR的定义和算法总结。可以供大家学习和参考(The SNR of a very comprehensive summary, which includes a variety of definitions and algorithms related to SNR summary. We can study and reference for)

该文件是一个详细分析PID控制的文件。通过示波器，改变参数下，可以很形象的观察输出波形的变化，这样可以更加直观的学习PID控制，加深对它的理解(The file is a detailed analysis of PID control file. Through the oscilloscope, change the parameters, can be very image of the observed output waveform change, so that we can more intuitive learning PID control, deepen the understanding of it )

振动信号预处理，主要为五点三次平滑法和平均法(Vibration signal pre-processing, mainly for the 5.3 second smoothing method and average method)

this is matlab user-guide.

电动助力转向的仿真模型，是本科毕业设计。(The simulation model of the electric power steering is a graduate design.)

双闭环pi控制的svpwm仿真，simulink仿真模型(Svpwm pi-controlled double-loop simulation, simulink simulation model)

matlab用蚁群算法求解TSP问题的基本程序，初学者必看(TSP with ant colony algorithm matlab' s basic program, beginners must see)

利用灰色模型进行电力负荷预测，输出预测数值及其与实测值的误差曲线(power load forecasting by Grey model )

基于MATLAB神经网络工具箱的BP网络实现，该本书对初学神经网络的读者应该比较有用。(Based on the MATLAB neural network toolbox of the BP network, the book for beginner readers neural network should be more useful.)
