中文摘要
      紧急情况下, 应急网络控制系统为人员提供远程控制能力, 但系统仍存在一定故障率, 且故障影响会利用系统灵活传输机制快速扩散, 因此研究如何在故障快速扩散的情况下对系统实施故障控制, 对保证系统安全运行具有重要意义. 本文提出考虑传播过程的应急网络控制系统故障恢复策略. 首先, 基于复杂网络模型建立故障传播模型, 定义传播路径上的故障强度, 将分析故障信息关键传播过程转化为查找系统最大可能传播路径的问题, 进而在连接边的故障传播属性乘积大于终止条件时, 找到最大概率故障传播路径, 有针对地布置故障检测点; 再根据检测到的故障形式及检测点位置生成故障恢复策略库, 结合系统可调度性和故障恢复效果, 确定最优故障恢复策略. 最后, 以舰船应急火炮控制系统构建案例, 验证方法可行性, 并设置多节点故障, 验证算法鲁棒性, 仿真结果表明, 在不同故障情形下均能制定最优故障恢复策略.
英文摘要
      In case of emergency, the emergency network control system provides the remote control ability for the personnel, but the system still has a certain failure rate, and the influence of the failure will spread rapidly by using the flexible transmission mechanism of the system, therefore, it is of great significance to study how to implement fault control under the condition of rapid fault diffusion to ensure the safe operation of the system. In this paper, a fault recovery strategy for emergency networked control systems is proposed, which considers the process of fault propagation. Firstly, a fault propagation model is established based on the complex network model, and the fault intensity on the propagation path is defined, which transforms the analysis of the key propagation process of fault information into the problem of finding the maximum possible propagation path of the system, then, when the product of fault propagation attributes is larger than the termination condition, the most probable fault propagation path is found, and the fault detection points are arranged accordingly. Then, according to the detected fault and the location of the detection point, the fault recovery strategy library is generated, and the optimal fault recovery strategy is determined by combining the schedulability of the system and the effect of fault recovery. Finally, a case is built to verify the feasibility of the method and set up a multi-node fault to verify the robustness of the algorithm, the optimal fault recovery strategy can be formulated under different fault conditions.
