However, their growing reliance on communication networks increases vulnerability to cyberattacks, such as false data injection attacks (FDIAs). FDIAs modify data transferred over the PCS communication links. Addressing FDIAs requires detecting their presence, estimating their parameters, and mitigating their impact. This study examines the identifiability of FDIA parameters—precisely, the ability to estimate these parameters using observable process data. We present cases where attack parameters cannot be uniquely determined from observed data and assess their implications for attack estimation. First, we consider the case when the attack’s impact is indistinguishable from process disturbances or measurement noise. Second, we consider the case when the relationship between the observed data and the attack parameter values is not unique. Both cases result in a lack of identifiability in the attack parameter values from the process data. While the former is tied to inherent process and attack properties, the latter can be addressed using longer observation windows in estimation schemes. We explore these issues through different estimators and demonstrate their impact using a process example. Despite these challenges, we also present scenarios where accurate FDIA estimates can be achieved. Finally, we apply one of the estimators to a chemical process under simultaneous additive and multiplicative FDIAs, showcasing its effectiveness and validating its ability to estimate attack parameters accurately.</div></div>","PeriodicalId":10019,"journal":{"name":"Chemical Engineering Research & Design","volume":"219 ","pages":"Pages 181-197"},"PeriodicalIF":3.7,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144253879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The distribution characteristics of the airflow field and the dust migration law are investigated at heights of 0.3 m and 1.5 m. The results show that the recirculation zone formed on the farthest side of the air duct has a relatively high wind speed and serves as the main carrier for transporting dust particles. In contrast, the eddy current zone far from the outlet of the air duct has complex and disordered airflow, which significantly inhibits the transportation of dust. The density of dust particles is the decisive factor for the decline rate of dust concentration. There is more dust accumulation at the lower level, and the diffusion is slower. The reliability of the simulation results is verified by the on-site monitoring data.
