The increasing demand for enhanced cost-effectiveness and production efficiency has driven automation manufacturers to integrate PLC-based applications and systems with external networks, such as Internet. Unfortunately, this connectivity has exposed systems to potential malicious attacks from motivated adversaries. Addressing this pressing issue necessitates a comprehensive summary of ongoing research related to PLCs and their related systems. This summary should classify these systems based on disclosed vulnerabilities, potential threats, and proposed security solutions, catering to both scientists and industrial engineers. While several recent surveys have reviewed and discussed PLC security and related topics, they often fell short of covering all essential aspects comprehensively. Furthermore, prior surveys tended to focus on analyzing vulnerabilities at the system level, overlooking the vulnerabilities specific to PLCs themselves. Consequently, their findings failed to effectively secure current operational systems or propose improved solutions for future PLC designs. In this article, we bridge this research gap by providing a detailed review of all aspects concerning the security of PLCs and related systems. This includes vulnerabilities, potential attacks, and security solutions including digital forensics. We aim to offer a precise analysis, addressing the shortcomings of previous studies. Finally, we conclude this article by presenting our recommendations tailored for PLC manufacturers, researchers, and engineers. We hope that these recommendations will contribute to the development of more secure PLCs in the future.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"4 ","pages":"659-693"},"PeriodicalIF":8.5,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10328062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138678686","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}

Despite their advantages, increased connectivity and reliance on communication networks expand their susceptibility to cyber threats. Machine learning (ML) can radically transform cyber security in SGs and secure protocols as in IEC 60870 standard, an international standard for electric power system communication. Notwithstanding, cyber adversaries are now exploiting ML-based intrusion detection systems (IDS) using adversarial ML attacks, potentially undermining SG security. This article addresses cyber attacks on the communication network of SGs, specifically targeting the IEC 60870-5-104 protocol. We introduce a novel ML-based IDS framework for the IEC 60870-5-104 protocol. Specifically, we employ an artificial neural network (ANN) to analyze a new and realistically representative dataset of IEC 60870-5-104 traffic data, unlike previous research that relies on simulated or unrelated data. This approach assists in identifying anomalies indicative of cyber attacks more accurately. Furthermore, we evaluate the resilience of our ANN model against adversarial attacks, including the fast gradient sign method, projected gradient descent, and Carlini and Wagner attacks. Our results demonstrate that the proposed framework can accurately detect cyber attacks and remains robust to adversarial attacks. This offers efficient and resilient IDS capabilities to detect and mitigate cyber attacks in real-world ML-based adversarial environments.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"4 ","pages":"629-642"},"PeriodicalIF":8.5,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10328057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138633880","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 utilize the electrical drive to its maximum extent during transient and steady-state operation, a time-optimal continuous-control-set model predictive flux control (CCS-MPFC) for permanent magnet synchronous motors (PMSMs) is proposed. This scheme considers torque and current limits as softened state constraints in the CCS-MPFC's optimization problem to prevent transient overcurrents as well as torque over- and undershoots during time-optimal operating point changes. Furthermore, the overmodulation range including six-step operation can be entered seamlessly to ensure maximum power conversion at high speeds. Fastest transients within the whole modulation range are enabled by a time-optimal harmonic reference generator. Here, the flux reference of the CCS-MPFC is complemented with a harmonic content that enables operation in the overmodulation region. Further, the reference is prerotated during transient operation to attain time-optimal control performance. Extensive simulative as well as experimental investigations for linearly and nonlinearly magnetized PMSMs show that, compared with state-of-the-art methods, time-optimal control performance in the whole modulation range without transient overcurrents as well as torque over- and undershoots can be achieved by the proposed control method.","PeriodicalId":52675,"journal":{"name":"IEEE Open Journal of the Industrial Electronics Society","volume":"4 ","pages":"643-658"},"PeriodicalIF":8.5,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10324345","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138822193","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}

SMT-SHE approach achieves a sinusoidal-like output stepping voltage with variable output voltage amplitude and free of wideband or/and specific harmonics to fulfill the sensitive loads’ specifications; by determining the appropriate SHE switching angles. The precalculated switching angles are optimized to minimize the number of H-bridge modules and lower the dc capacitor rating.

However, for linear topology applications, the LoRaWAN protocol requires the introduction of a large number of gateways, which will lead to information asymmetry, energy waste, and low network utilization. An energy-saving LoRa linear network system with adaptive transmission parameter is proposed. LoRa multihop technology is used for communication between nodes in the system, and narrowband Internet of Things module is used to the communicate with cloud platform. The adaptive transmission parameter mechanism is adopted in the system, which improves the adaptability of the linear network to changes in link channel conditions and reduces unnecessary energy consumption. At the same time, the flexibility and robustness of self-organizing networks are enhanced. In addition, optimized duty cycle strategies are employed to further reduce the operating power consumption. After LoRaSim simulation experiments, the results show that in the changing radio channel environment, the adaptive transmission parameter mechanism could achieve a dynamic balance between data extraction rate and energy consumption. After field tests, the results show that the system not only operates stably, but also could reduce the operating energy consumption of the LoRa linear network.

This article proposes a practical strategy of assessing the benefits of using wireless communication technologies (WCTs) in power electronics systems (PESs) employing AGDs. First, information transmission routes (ITRs) are identified and located within a PES. Second, an ITR taxonomy is proposed, classifying ITRs and describing both application scenarios and requirements for every class. After presenting general advantages of WCTs over wired alternatives, seven specific WCTs are individually characterized. Subsequently, the benefits of using WCTs are evaluated for each ITR class, resulting in a specific recommendation for or against the use of WCTs, and at least one appropriate WCT for each ITR. Experimental results demonstrate that the wireless control of AGDs for SiC power \u0000<sc>mosfet</small>\u0000s is feasible using Bluetooth low energy.
