matlab，实现永磁同步电机调速。pid控制(matlab pmsm pid controller)

this mfile is riten in matlab and is related to mirtoolbox

说明：  matlab的一本国外原版书，感觉还可以(matlab abroad of an original book, the feeling can also be)

功率谱估计性能分析及其MATLAB实现，间接法、直接法、改进的周期图法Welch法、Bartlett法 (Power spectrum estimation performance analysis on MATLAB, the indirect method, direct method, improved periodogram the Welch Law, Bartlett method)

说明：  改进遗传算法，与模拟退火算法结合使用。准确性提高了不少。(The improved genetic algorithm is combined with simulated annealing algorithm. The accuracy has improved a lot.)

说明：  对高光谱，拉曼光谱可以做特征提取的思路，先做案例，搞懂后再移植到自己的实验里。(For hyperspectral, Raman spectrum can do feature extraction ideas, first do cases, understand and then transplant to their own experiments.)

说明：  随机共振是一种新颖的信号降噪方法，适量的噪声能够共振出隐含的特征频率。(SR is a good method to denoise signals.)

Fourier coherence This program calculates the fourier coherence of a signal using cpsd function of matlab. Input and output are explained in file.

声波方程正演,时间域，加吸收边界条件，可以自己编辑模型(Acoustic wave equation forward, time domain, plus absorbing boundary conditions can edit their own model)

说明：  介绍神经PID控制，包括：基于神经元网络、BP神经网络、RBF神经网络等PID整定的讲解和相关的源代码(err)
