用simulink建立的直流电机模型，可以用来在电动汽车模拟中运行和分析(The DC motor model established by Simulink can be used in the simulation of electric vehicle.)

matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )

This function is for optimization. To be specific, name of file is Truss_Solver_and_Genetic_Algorithm_Optimzer. With last function, you can try build up bridge as an example.

多进制PSK调制的matlab实现程序，能过实现M进制的psk调制(Ary PSK modulation matlab implementation program that can achieve over the psk M-ary modulation)

说明：  2个程序，MATLAB设计的一个滤波器，将含3个频率分量的信号通过该滤波器，滤除2个高频分量，得到只含低频的信号。 单边带信号调制，用MATLAB实现，是学习信号调制的一个好例子。(Two procedures, MATLAB design a filter, will contain three frequency components of the signal through the filter, filter out high frequency components of two, has been only with low-frequency signal. SSB signal modulation, using MATLAB to achieve, is to study signal modulation of a good example.)

根据公式I（n-1）=（1-In）/n 令I11=0计算I1 到I10； 根据公式In=1-nI(n-1) 令I0=0.6321 计算I1到I7； 根据公式X2=a ， 令a=2，计算X的值。(According to the formula I(n-1)=(1-In)/n ，set I11 equals zero，and count I1 to I10. According to the formula In=1-nI(n-1)，set I11 equals zero，and count I1 to I10. According to the formula X square equals a ，set a equals two ，then calculate X )

simulink滤波率仿真 二阶和四阶低通滤波(filtering rate simulation simulink second and fourth-order low-pass filter)

Classical 180 command for inverter fed induction motor

说明：  由于matlab代码中若有很多循环结构，执行效率就会降低。本文献教你怎么写出高质量的matlab代码(Because if many matlab code cycle structure, the implementation of the efficiency is reduced. The literature teach you how to write high-quality matlab code)
