里面包含了大量的matlab的m文件，主成分、PLS等算法，还包括了傅里叶变换等海量代码，绝对好东西(Which contains a large number of matlab m-file, the main component, PLS and other algorithms, including Fourier transform mass code is absolutely a good thing)

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.)

Hilbert-黄变换中的核心程序EMD[Rilling版]，程序中附加了详细的中英文注释以及参考文献，可以让使用者对EMD的原理更加明确，并对HHT的理解和应用大有裨益。(EMD,originally programed by Rilling, is a core subroutine in the Hilbert-Huang Transform(HHT). This subroutine attaches a detailed notes and references both in English and Chinese. It will greatly benefits the users on the principle of EMD. Furthermore,it will help the users and schoolers much more during the application and research of HHT.)
