基于matlab上进行扩频技术的仿真研究（M文件实现）(Matlab based on the simulation of spread spectrum technology (M documents to achieve))

说明：  一个完整的永磁同步电机SVPWM控制模型(A complete model of permanent magnet synchronous motor SVPWM control)

作业题 就是说matlab中的常微分方程问题，是有ode45(operations that Matlab is the ordinary differential equations, have ode45)

基于wilson法的风力机叶片设计，应用MATLAB中fmincon函数对轴向和周向诱导因子求解(Wilson law-based wind turbine blade design using MATLAB fmincon function of the axial and circumferential inducible factor solution)

1、设计一个62阶低通滤波器，采样频率为9kHz，通带截止频率为3kHz，要求阻带最小衰减50dB。 2、将滤波器系数输出到txt文本文档。 (1, the design of a 62-order low-pass filter, the sampling frequency is 9kHz, passband cutoff frequency of 3kHz, requires a minimum stopband attenuation 50dB. 2, the output of the filter coefficients to txt documents.)

说明：  在matlab2019B中，已经将princomp函数改为了pca函数，功能相同，函数名改变，所以如果要使用，记得将老版本的代码中的princomp改为pca。(In MATLAB 2019b, the principal function has been changed to PCA function. The functions are the same, and the function name changes. So if you want to use it, remember to change the principal function in the old version of the code to PCA.)

矢量控制解耦模型比较仿真，主要包括反馈解耦，前匮解耦，和交叉解耦三种模式。(Simulation of vector control decoupling model comparison)

讲述了一种基于RS吗的软扩频通信及其simulink仿真(About you based on the soft RS simulink simulation of spread spectrum and its)

关于数字带通滤波器的编码matlab程序。可以作为函数直接引用。(Digital bandpass filter encoding matlab program. As a function reference.)
