Considering that the mechanical equipment may experience different operating conditions during operation, a meta-domain-adversarial neural network (MDANN) is established for improving the adaptability of transfer models in multi-target-domain fault diagnosis, which utilizes meta-learning technique to view the multi-target-domain fault diagnosis as multiple tasks. In the data preprocessing stage, the continuous deep belief network is selected for outliers removal. Furthermore, to make the MDANN model available for the partial domain multi-target-domain fault diagnosis problem, a new group-wise comparison approach is proposed. Compared with the existing results, the proposed MDANN allows one trained fault diagnosis model to cope with different operating conditions, and it can be extended to address scenarios where the label spaces in the source and target domains are different. Finally, the proposed fault diagnosis method is experimented on the bearing datasets and compared with several state-of-the-art approaches, which proves its superiority and effectiveness.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed model addresses a spectrum of real-world scenarios encountered in manufacturing environments, including CNC machine failures, robotic server breakdowns, reneging behavior of failed CNC machines, and mechanisms to handle unsatisfactory repairs. In this system, failed CNC machines are attended by a single robotic server following a first come first served protocol, while also accounting for potential breakdowns of the robotic server during servicing. The arrival of failed CNC machines is regulated using the F-policy, and repairs to the robotic server are conducted following Bernoulli's p-phases under a threshold recovery (Q) policy. Through the development of steady-state equations of a system and their solutions through matrix-analytic techniques, the distribution of queue sizes within the system is derived. Numerical results are presented graphically to illustrate the influence of various parameters on overall system performance. Additionally, sensitivity analysis on total expected costs are conducted to assess the impact of parameter variations. To optimize system costs, three meta-heuristic approaches are employed: Particle Swarm Optimization(PSO), Ant Colony Optimization(ACO), and Flower Pollination Algorithm(FPA). Comparative analysis of these techniques' performances is conducted using data generated through their application. This novel combination of theoretical modeling, numerical analysis, and meta-heuristic optimization offers a comprehensive framework for enhancing efficiency and cost-effectiveness in CNC machining workshops.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the position tracking errors are constrained by designing the barrier Lyapunov function, and the prescribed performance function is set as the constraint boundary to address the issue of fixed constraint boundaries in traditional methods. Secondly, RBF neural networks are employed to estimate the model uncertainties, and adaptive laws are used to estimate the upper bound of the composite disturbances. Finally, the controller is designed by incorporating fixed-time convergence theory and further using fixed-time sliding mode surface in order to overcome the shortcomings of traditional control algorithms in terms of slow response and the use of finite-time convergence with respect to the initial state. Through Lyapunov stability analysis, it is proven that all signals in the closed-loop system are bounded, and the velocity tracking errors can achieve global fixed-time convergence. Simulation results demonstrate that the proposed control scheme enables underactuated ship to achieve trajectory tracking even in the presence of input saturation and dead zone. Statistical results show that the performance indicators of the proposed controller are significantly smaller than those of the first group in the comparative experiments, with a shorter settling time. Moreover, compared to traditional saturation handling methods, the input curves of the proposed controller are smoother and more aligned with practical engineering requirements.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143782366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limitation of the linear ADRC lies in its inability to adequately reject time-varying disturbances. Modified ADRC strategies discussed in this manuscript, including LESO-based proportional integral derivative-ADRC (LESO-PID-ADRC) and proportional resonant-ADRC (LESO-PR-ADRC), exhibit the capability to proficiently track ramp and sinusoidal references while effectively suppressing similar disturbances. Additionally, a quasi-generalized integrator-extended state observer based PID-ADRC (QGI-PID-ADRC) is proposed which is capable of tracking both step and ramp references while simultaneously rejecting ramp and sinusoidal disturbances. Furthermore, maximum sensitivity constrained region (MSCR) based graphical tuning approach is presented for the PID and PR controllers. Frequency domain analysis is conducted to illustrate reference tracking and disturbance rejection capability of the designed controllers. Moreover, stability of the closed loop system is illustrated using Nyquist plots. Simulation study is conducted in MATLAB for two complex systems (ship motion model and pressurized water reactor (PWR)) which have associated nonlinearities, time-varying system parameters and modeling uncertainties. The research demonstrates that LESO-PID-ADRC, QGI-PID-ADRC and LESO-PR-ADRC, when tuned using the proposed graphical approach, outperform recently introduced control strategies, excelling in both reference tracking and disturbance rejection.","PeriodicalId":94059,"journal":{"name":"ISA transactions","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
