详细说明了在大型电力系统分析软件中建立双馈风机模型的方法以及稳定分析中的模型降阶简化方法。-Describe a simplified method for the DFIG model as well as in large-scale power system analysis software stability analysis model reduction.

高阶buck电路的模型降阶，krylov子空间法，arnoldi算法-the reduction of the full-order model of Buck converter,Krylov subspace,Arnoldi algorithm

四阶格型滤波器，较二阶，三阶误差更小，收敛速度变快，50次即可迭代完成，在降噪方面有显著效果。(Four order lattice filter, compared with the two order, three order error is smaller, faster convergence speed, 50 iterations can be completed, in terms of noise reduction has a significant effect.)
