Finding Faults: a scoping study of Fault Diagnostics for Industrial Cyber-Physical Systems

As Industrial Cyber-Physical Systems (ICPS) become more connected and widely-distributed, often operating in safety-critical environments, we require innovative approaches to detect and diagnose the faults that occur in them. We profile fault identification and diagnosis techniques employed in the aerospace, automotive and industrial control domains. Each of these sectors have adopted particular methods to meet their differing fault diagnostic needs. By examining both theoretical presentations as well as case studies from production environments, we present a profile of the current approaches being employed.随着工业信息物理系统（Industrial Cyber-Physical Systems, ICPS）的互联程度不断提升、部署愈发广泛，且其常运行于安全关键型环境中，我们亟需创新方法来检测并诊断其中出现的各类故障。本文调研了航空航天、汽车及工业控制领域所应用的故障识别与诊断技术，各领域均针对自身差异化的故障诊断需求采用了专属的技术方案。通过对理论阐述内容与生产环境中的案例研究进行考察分析，本文对当前所采用的各类故障诊断技术方案进行了全面梳理。
