F-16，flightgear and matlab 仿真(F-16，flightgear and matlab simulation)

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，进行实验仿真，比较不同的窗函数，不同的数据长度对Welch法谱估计质量的影响，并分析了造成这些影响的原因。(The paper mainly introduces the principles of Periodogram method of classical PSD estimation,analyzes the deficiency of Periodogram method in theory,and makes use of Welch to amend Perodogram method. By the use of simulation in Matlab, the impacts of different window function and different lenghth of data on estimation quality of Welch are discussed and the reasons of the impacts are analyzed.)

利用电压电流泰勒展开，计算极限潮流分布，也可计算不同负荷情况下的潮流分布，只要改动负荷因数K的大小即可(Taylor voltage and current use to calculate the limit flow distribution, flow distribution can also be calculated under different load conditions, as long as the changes in the size of the load factor K can be)

利用有限元方法求解悬臂梁的振动问题,输入节点数可以算出前六阶振型，计算固有频率(Using the finite element method to solve the vibration problem of a cantilever beam, the input nodes can calculate the first six vibration mode, calculate the natural frequency)
