To address these challenges, this research develops a mathematical model for the switching transition between 10 kV SiC \u0000<sc>mosfet</small>\u0000s and complementary 10 kV SiC JBS diodes in a two-level clamped inductive switching (CIS) test setup.

This study compares six modulation methods for MMCs: Nearest Level Control (NLC), Integral Modulation (IM), and PWM using a traditional sorting algorithm, alongside their modified versions featuring the novel sorting algorithm. The effectivenss of each modulation technique discussed in this article is verified through experimental tests. The results show that the proposed modulation techniques utilizing the suggested sorting algorithm, effectively decrease the switching number while maintaining the THD of the load currents. However, there is a slight increase in the disparity of the capacitor voltages, which remains controllable. In addition, the study fills a gap in the literature by providing experimental evidence and a theoretical framework demonstrating the superior efficiency of IM over NLC through frequency analysis and experimental results.

Thus, the topology is provided merging the cascaded bidirectional Boost converter and cascaded bidirectional Cuk converter. Subsequently, the coupled mathematical model of the proposed topology can be readily calculated, considering all feasible (different) subcircuits according to the switching pattern. Therefore, small-signal analysis is applied to design the PI controllers, followed by a closed-loop performance evaluation using an infinity norm and stability analysis to assess the operation of the dc/dc converter in closed loop for different values of load and current references. Finally, a lab-scale prototype and a hardware-in-the-loop setup prove the effectiveness of the dc/dc converter working in various scenarios and also operating with the traditional SoC-based droop for balancing the BESS units.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"5 ","pages":"898-915"},"PeriodicalIF":5.2,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10643290","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, the article proposes a technology-agnostic, semantic event-handling module to address the challenge of enhancing explainability within CPS. This module is designed to be part of the common architecture for Explainable CPS and, therefore, can be integrated seamlessly into existing CPS frameworks by providing different interfaces to access detected events. Two case studies in the smart building and smart grid domain are carried out to demonstrate the feasibility and efficacy of the approach, utilizing an open-source software stack for the prototypical implementation. A qualitative evaluation of the proposed approach, based on the ISO/IEC 25010:2023, was used to analyze the software design. Our evaluation result shows that the semantic event-handling module is appropriate as a generic approach to handling events within a CPS.

Given the intricate interplay among these domains, employing ontologies for knowledge representation could hold the key to capturing all necessary relationships and constraints for effective risk management processes. This study conducts a systematic mapping analysis of ontologies published over the past five years, focusing on at least one domain relevant to OT system risk management. Its objective is to categorize papers, offer a panoramic view of research themes and contributors, discern potential publication patterns, and identify research avenues based on a comprehensive review of these ontologies. Findings indicate a relatively stable research interest, with most publications presenting proof of concepts or initial experimental results for their ontological applications.

In realistic hardware, they are often difficult to cross-check for accuracy and reproducible results. The accurate memristor model prediction becomes critical to decipher the overall circuit function in a wide range of nonideal and practical conditions. In most neuro-memristive systems, crossbar configuration is essential for implementing multiply and accumulate calculations, that form the primary unit for neural network implementations. Predicting the specific memristor model that best fits the crossbar simulations to make it explainable is an open challenge that is solved in this article. As the size of the crossbar increases the cross-validation becomes even more challenging. This article proposes predicting the memristor device under test by automatically evaluating the \u0000<italic>I–V</i>\u0000 behavior using random forest and extreme gradient boosting algorithms. Starting with a single memristor model, the prediction approach is extended to memristor crossbar-based circuits explainable.

Thus, an integrated risk assessment approach is essential to identify and address potential hazards and vulnerabilities. However, conducting such risk assessments becomes complex and challenging due to the difficulty in data availability. Acquiring data from various sources poses a significant hurdle. To address these challenges, automation markup language (AML) provides a standardized framework that facilitates the seamless exchange of engineering information. This article uses AML libraries and connection setup techniques to generate a valuable model of a single source of data for an integrated safety and security risk assessment. The automated risk assessment employs the AML model as a data source and the Bayesian belief network (BBN) as the risk assessment method. The value of risk associated with the system is calculated using the BBN models as the product of the probability of occurrence and severity. An evaluation of the proposed risk assessment method is also provided based on ISO 31000.

To this end, we experimentally identified the effects of replacing the communications subsystem of a legacy Ethernet-based network with TSN in terms of synchronization. Based on the results, we propose a solution called TALESS (TSN with Legacy End-Stations Synchronization). TALESS can identify the drift between the TSN communications subsystem and the integrated legacy devices (end-stations) and then modify the TSN schedule to adapt to the different time domains to avoid the effects of the lack of synchronization between them. We validate TALESS through both simulations and experiments on a prototype.

Structure-borne noise analysis is used to evaluate the equivalent radiated power level of three designed PMSMs with different stator vibration mode orders. One-way multiphysics analysis using finite element analysis (FEA) is performed in a water environment for the finally-selected PMSM with pod housing structure.
