to get the solution of Orr-Sommerfeld equation

这个程序是采用牛顿法来进行潮流计算，系统的参数需要手动输入，相关的说明在程序里有,需要输入两个矩阵，节点和线路的矩阵(This program is the use of the Newton method for power flow calculation, the parameters of the system need to manually enter the description in the program)

说明：  核主元分析是一种常见的数据分析方式,常用于高维数据的降维,可用于提取数据的低维特性。(Kernel principal component analysis is a common way of data analysis, which is often used to reduce the dimension of high-dimensional data and extract the low-dimensional characteristics of data.)

说明：  hht希尔伯特黄变换，自己使用，经过验证之后，能出结果的(HHT Hilbert Huang transform, their own use, after verification, the results can be)

地球物理专业的地震波数值模拟程序，matlab编写，大家交流学习。。(Geophysics, seismic wave numerical simulation program, matlab prepared to share learning. .)

求解线性规划的单纯形法，M文件，里面有注释，可以求标准的线性规划问题。(Solve the linear programming of the simplex method, there are comments )

交流伺服系统中的死区效应分析与补偿分析了逆变器的死区效应产生的原因及其对交流伺服系统控制性能产生的影响,指出死区补偿的关键 在于电流相位的获取,为了克服实际系统中电流零点的模糊性,提出了一种基于两相静止坐标系下的前馈死 区补偿方法. 该方法通过对三相输出电流一个周期内补偿电压进行傅里叶变换,发现仅需补偿1 ,5 ,7 次谐波 分量即可消除死区效应. 仿真和试验结果验证了这种方法的正确性和可行性.(AC servo system analysis and compensation of dead time effect of the inverter dead time effect causes the impact of the control performance of the AC servo system, and pointed out that the dead time compensation, the key lies in the current phase of the acquisition, in order to overcome the practical zero of the current ambiguity of the system is proposed based on the two-phase stationary coordinate system under the feedforward dead-time compensation method. by the offset voltage of the three-phase output current cycle Fourier transform is found only compensation 1, 5, 7 harmonic components to eliminate the dead time effect. simulation and experimental results verify the correctness and feasibility of this approach.)
