Fault recovery of emergency networked control system considering propagation process
摘要
Abstract
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.关键词
