However, it is challenging to accurately extract entry and exit moments of the fault from noise-contaminated raw signals. To address this issue, a novel quantitative diagnosis method based on digital twin model is proposed to assess the fault severity from the original signal waveform. Specifically, the quantitative diagnostic criterion for bearing faults is derived to reveal the instantaneous response characteristics of dual-impulse behaviors, and then a digital twin model is constructed to characterize the fault characteristics of the measured signal with noise-free twin signals. Subsequently, a recursive parameter optimization strategy based on cosine similarity (RPOS-CS) is proposed to optimize the twin model in real time, and fault parameters of the optimal signal will be applied to evaluate the fault size of the bearing. Finally, kernel density estimation is employed to perform uncertainty analysis on multiple diagnosis results, thereby realizing interval estimation and significantly enhancing the reliability of diagnosis results. Both simulated and experimental signals are utilized to validate the efficacy of the proposed method, and the further comparative analysis shows that it exhibits high diagnostic accuracy and outstanding reliability.</div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"157 ","pages":"Pages 381-391"},"PeriodicalIF":6.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It further describes a four-stage design strategy that sequentially enhances tracking responses, reduces overshoot, and ensures robustness for unstable time-delayed (UTD) processes. The controller applies to integrating and non-integrating UTD processes of any order and does not necessitate model order reduction or delay approximation. The strategy involves four stages, each targeting a specific aspect of performance improvement. The first stage designs the optimal and robust FOPD (ORFOPD) controller to accelerate tracking responses. In the second stage, the cascade optimal and robust PI (ORPI) controller ensures zero steady-state error. A gain and phase margin (GPM) tester determines the feasible specification-oriented regions (FSORs) on the <em>K</em><sub><em>P1</em></sub>-<em>K</em><sub><em>D1</em></sub> and <em>K</em><sub><em>P2</em></sub>-<em>K</em><sub><em>I2</em></sub> planes, aiding in selecting the ORFOPD and ORPI controllers to minimize the IAE or ISE index under ± 10% loop gain perturbations (LGPs). The third stage schedules setpoint weighting coefficients to reduce overshoot typically associated with UTD processes. The final stage uses a prefilter to refine the reference input signal and mitigate overshoot. A systematic design procedure is summarized to rapidly compute all controller gains in a step-by-step sequence. This SWPI-FOPD controller with a prefilter enhances robustness, provides rapid tracking response with zero steady-state error, and effectively reduces overshoot and IAE or ISE, even with ± 10% LGPs. Comparative simulations across three examples, along with a practical jacketed CSTR application, validate the feasibility and demonstrate the superior performance of the proposed controller.</div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"157 ","pages":"Pages 164-185"},"PeriodicalIF":6.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142901458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims to ensure system communication connectivity and allow followers to achieve distributed secure bipartite TVFT. To enable followers to successfully obtain unknown state of the leader, this paper designs a composite adaptive dynamic event-triggered (DET) bipartite compensator.

Based on proposed compensator, a new distributed formation controller is designed for achieving TVFT.
