基于多智能体的复杂工程系统故障诊断研究

为了解决动态多变环境下的故障诊断问题，引入智能Agent技术，建立了一种基于多Agent的分布式故障诊断模型，该模型由多个分布于不同区域的Agent工作组组成，是一个分布式远程多Agent诊断系统。该系统主要由诊断Agent和管理Agent组成，通过各Agent之间的通信与协作实现多变环境下的故障诊断。实践证明，该诊断系统不仅能对各种故障作出及时反应，而且能准确给出诊断结果。

Fault Diagnosis for Complex Engineering System Based on Multi-agents

To fulfill the fault diagnosis under dynamic environment, a distributed fault diagnosis model was presented based on multi-agents for constant and dynamic conditions. As a distributed remote multi-agent diagnosis system, the model consisted of several widely distributed Agent Workgroups. This model was mainly made up of the diagnosis-agent and the management-agent. The former was composed of multi-sensors information fusion algorithm while the latter functions through blackboard model. Then, the fault diagnosis under dynamic environment was realized through communication and cooperation among various agents. Finally, by analyzing an experiment result, it is shown that the model is effective.
