In the situation, this paper brought up the risk analysis and evaluation method on the basis of intelligent control and network communication technology for Network Communication System. The risk analysis and evaluation of Network Communication System firstly discussed the character of network communication and its risk. At the following we estimate a risk evaluation model according the distribution of the systems risk by time and space. Otherwise, we combined Fuzzy Comprehensive Evaluation with Analytic Hierarchy Process, and set up the multi-grade fuzzy comprehensive evaluation model for Network Communication System.

该方案主要通过讨论网络通信系统及其风险的特性，根据风险的时间和空间分布规律，以"风险"为整个网络通信系统安全模型的评估和分析对象，确立网络通信系统风险分布的量化评估模型，同时，就不同区域和不同时段的风险通过引入层次分析的一般方法来确定它们的权重系数，最后，通过模糊综合评判法则对系统中模糊不确定性因素进行数学化的抽象，建立一个反映其本质特征和动态过程的理想化的数学评估模型。

There is an element of risk and uncertainty in each of these situations.

Robust aposteriori L〓 filtering to noise inputting matrix uncertainty system can be reduced to the solution of a linear matrix inequality too.

对噪声输入矩阵不确定性情况下的鲁棒L〓验后滤波，本文的解法也归结为一凸优化问题，可有效的求解。

The apriori and aposteriori H〓-optimal filtering question can be solved directly. L〓 Apriori and aposteriori filtering with an H〓 error bound can be solved by semidefinite programming. Robust H〓 apriori filtering and robust apriori L〓 filtering in discrete-time system are subject to a nonconvex constraint.

对这些滤波问题解法的改进同连续系统下的情况基本类似，对确定性系统的H〓验前滤波和验后滤波，本文解法可直接得出最优滤波问题的解；对H〓约束下的L〓验前滤波及验后滤波，其解可归结为一凸优化问题；但不确定性系统H〓验前滤波和鲁棒L〓验前滤波的LMI解法中有了非凸约束，因此要用迭代法求解。

Because of appearing empty aggregates in the time zone (the time zone do not include the information), we only establish the indeterminate grey differential equation according to the approximate condition of the differential equation.

利用灰色微分方程中的最小二乘估计参数：进而得到灰色神经网络初始的权值及阈值，这样使初始的权值和阈值更接近准确值，克服了以往BP网络中初始权值的随机性和不确定性，减少了网络的训练次数，提高了网络收敛速度和输出的精度，为避免网络训练陷入局部极小值也起到了重要的作用。

Actually,there are lots of uncertainties in real systems,such as model approximation, algorithm error etc,which have great impact on dynamic stabilities.

实际上，由于模型的近似表示和算法上的近似处理等，电力系统中还存在着大量的不确定性。
