Using the synthetic item, it can evaluate correctly internetworks and overcome the error produced by the pure reliability or performability evaluation.

这样的思想导致了我们提出对互连网络可靠性性能进行综合评价的方法来。

On the basis of common GM(1,1) model and by means of establishing residual error periodic extensional model, the authors extract predominant period and reconstruct a new data sequence; then after superposing the values of the same time in different period, a ray-periodic extensional combinatorial model is built.

提出了灰色–周期外延组合模型，即在一般灰色模型GM(1，1)的基础上建立残差周期外延模型，并提取优势周期以重新构造新的数据序列，再将不同周期同一时刻的值叠加。

In order to reduce the periodic current tracking error of the deadbeat control when compensating abruptly changing nonlinear load current, a repetitive controller is plugged into the deadbeat controller. Also, the repetitive controller can alleviate the parametric dependency of the deadbeat control and eliminate the effects on compensation performance caused by the uncertainties in the system.

另外，为了降低无差拍控制对系统参数的依赖型和系统中存在的不确定性对补偿性能的影响以及减小在补偿电流变化剧烈的非线性负载电流过程中存在的周期性的局部跟踪误差，本文在无差拍控制器的基础上，又提出了基于无差拍和重复控制的复合电流控制器。
