增广矩阵

By means of augmented Lyapunov functional and free-weighting matrix approach,a delay-dependent sufficient condition is presented,which can make the resulting closed-loop systems asymptotically stable and satisfy a prescribed H∞ norm-bounded constraint.

利用增广Lyapunov泛函并结合自由权矩阵方法，得到使得闭环系统鲁棒渐近稳定且具有给定的H∞性能的时滞相关充分条件。

H∞ control ; augmented Lyapunov functional ; delay-dependent ; linear matrix inequality

It was proved that the design of the observer and the state feedback controller of the augmented system satisfied separation principle.

证明了观测器与增广系统状态反馈的设计满足分离原理，利用线性矩阵不等式给出了相应的控制器的设计。

Another is that retaining the refined Ritz vector in the new subspace,calledaugmented Krylov subspace.This way retains useful information and makes theresulting algorithm converge faster.

改进后的求解子空间为一增广Krylov子空间，该空间中包含更丰富的特征向量信息，因此用精化Arnoldi方法在该空间上求解矩阵特征问题时收敛速度更快。

First, we introduce the principle of feeder protective apparatus and select adequate protective equipments in accordance with different types of distribution system, using the least square error method to simulate the time/current curve and applicate simulation formula to digital the curve data, Secondary, using augmented incidence matrix method to find the exact pairs of primary/backup protection relay and find the relay tripping sequence of distribution lines.

首先介绍线路之过电流保护设备动作原理，依不同之配电系统型态来选用适当之保护设备种类，并使用最小平方误差法模拟保护电驿之时间－电流特性曲线，应用模拟方程式将曲线之资料数位化，且藉由图形理论中之增广关联矩阵法求取正确之主保护与后卫保护电驿对，以找出系统中各配电线路保护电驿间之跳脱顺序关系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
