对于我们电气专业的仿真而言，我们主要用到的可能是Simulink工具箱，SimPowerSystem工具箱。当然也有可能涉及到SimExtra工具箱。但主要是实用前两者来进行电力系统，电力电子和电机等方面的仿真。因此在进行这些仿真的时候，有一些基本的原则：(For our simulation of electrical expertise, we may be used in Simulink main toolbox, SimPowerSystem toolbox. Of course, there may relate to SimExtra toolbox. But mostly for the first two practical power systems, power electronics and motor and other aspects of emulation. Therefore, when conducting these simulations, there are some basic principles:)

说明：  平均周期图法和平滑平均周期图法估计功率谱 从经典功率谱估计周期图法原理入手，从理论上分析了其存在的局限性，借助Welch算法对其进行修正。依靠Matlab强大的数值分析和信号处理能力进行实验!! 用周期图法和welch法分别估计了一下信号的功率谱密度。采样频率200Hz，时间序列长度2048，FFT数据点数2048。其中welch法使用hanning窗，窗口长度600．(Average periodogram and periodogram smoothing method to estimate the average power spectrum from the classical power spectrum estimation periodogram principle starting from the theoretical analysis of the limitations of its existence, with the Welch algorithm, amending them. Rely on the powerful Matlab numerical analysis and signal processing capabilities to experiment!! With periodogram and welch method were estimated signal power spectral density about. Sampling frequency of 200Hz, the time sequence length 2048, FFT data points 2048. Welch method which uses hanning window, the window length of 600.)
