　　本文提供了一个分析　　复杂的动态显示当前模式控制　　开关电源转换器。电流型控制的提高　　转换器与非线性分析和研究　　离散建模方法已被使用。通过改变　　电路参数、混乱和复杂的行为　　分歧发生在开关电源转换器。为　　增加稳定period-l操作范围,坡道　　已经被改变其使用和补偿方法　　转换器的边坡,其效果将被显示。最后, 　　最大平均Iyapunov指数不同的斜坡上　　审查和模拟。(The present article provides an analysis of complex dynamics displayed by current mode controlled switching dc-dc converter. Current-mode controlled boost converter has been studied with nonlinear analysis and the discrete-time modeling approach has been used. By changing circuit parameters, complex behaviors like chaos and bifurcation occur in the switching dc-dc converter. For increasing stable period-l operation range, the ramp compensation approach has been used and by changing its slope, its effect in the converter will be shown. Finally, the largest average Iyapunov exponent for different slopes is reviewed and simulated)

in this package are the programs needed to solve any system of nonlinear equations

清华大学张旭东老师现代信号处理第二次matlab习题(The second matlab exercise in modern signal processing by Xudong Zhang, Tsinghua univ.)

说明：  pq分解法解电力系统潮流程序，不包含算列，用ieee节点信息(pq decouple)

利用x(n)=Asin(pi*n/16)+z(n),z(n)为mean=0，var=0.1高斯白噪声，x(n)的SNR为10dB,s(n)=Asin(pi*n/16-5*pi),得出了x(n)和s(n)互相关函数r(n)，以及二者的卷积和.(The utilization for the mean of x (n) = Asin (pi* n/16)+ z (n), z (n) = 0, var = 0.1 Gaussian white noise, x (n) is the SNR as 10dB, s (n) =Asin (pi* n/16-5* pi), draw the x (n) and s (n) the cross-correlation function r (n), as well as the convolution of the two.)
