摘　　要：在网络容错控制过程中存在响应时间长、控制效率低的问题,为此建立短时延多包传输网络容错控制数学模型。分析了容错控制模型原理,为降低检测过程的复杂度,依据分析结果采用割点检测方法检测传输网络的运行状态,并对不同的网络故障进行分类处理。以此为基础,设计主动容错控制器,利用控制器计算不同故障类型下的补偿控制量,通过数学迭代算法实现容错补偿控制,从而完成短时延多包传输网络容错控制数学模型构建。通过实验得出结论:与传统模型相比,该容错控制数学模型在控制过程中的响应时间较短,且控制效率较高,充分验证了上述方法的有效性与可行性。In the process of traditional network fault-tolerant control,the response time is long and control efficiency is low.Therefore,a mathematical model of fault-tolerant control for multi-packet transmission network with short delay was built.At first,the principle of fault-tolerant control model was analyzed.In order to reduce the complexity of detection process,cut-point detection method was used to detect the operation status of transmission network,and different network faults were classified.On this basis,the active fault-tolerant controller was designed.The controller was used to calculate the compensation control variables under different fault types.Finally,the fault-tolerant compensation control was realized by mathematical iterative algorithm,so that the mathematical model of fault-tolerant control of multiple-packet transmission network with short delay was built.Simulation results show that,compared with the traditional model,the response time of fault-tolerant control mathematical model is shorter and the control efficiency is higher,which fully proves the effectiveness and feasibility of the proposed method.
