These converters must operate in both maximum power point tracking and limited power tracking modes, which requires effective regulation of both PV voltage and inductor current using a dual-loop control structure. Reducing the input capacitance to eliminate electrolytic capacitors and increase lifetime, however, introduces significant parametric variations, making the control design challenging and limiting the dynamic performance of the voltage controller. This work proposes a dual-loop adaptive control strategy, comprising an outer voltage loop with model reference adaptive control and an inner current loop with a fixed-gain PI controller. The proposed method resolves issues observed in previous works in both steady-state and transient operation, enabling fast PV voltage tracking with an ultra-low 2 <inline-formula><tex-math>$mathrm{mu }$</tex-math></inline-formula>F input capacitor. Experimental results demonstrate stable operation in both continuous conduction mode and discontinuous conduction mode modes, with a settling time of 7 ms at a switching frequency of 40 kHz, improved dynamic response, and applicability in PV systems under rapidly changing irradiance conditions.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"547-562"},"PeriodicalIF":3.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11494296","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147828711","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}

This enables the design of a smaller motor that delivers the same torque output, offering a higher torque/power density. The proposed structure is also optimized and compared with alternative designs under the constraint of equal magnet volume to highlight its effectiveness.

However, the WF complexity, the black-box nature imposed by manufacturers’ confidentiality and cybersecurity constraints, and uncertainty in operating points hinder the practicality of analytical impedance models and the efficiency and effectiveness of data-driven impedance models. To tackle these challenges, this article presents an efficient data-driven approach leveraging Kolmogorov–Arnold networks (KANs) with transfer learning for impedance identification of WFs under heterogeneous data availability. This approach addresses the inherent limitations of training from scratch by enabling knowledge extrapolations from a source task with abundant data to target real-world scenarios characterized by data scarcity. The hyperparameters and training of the proposed model are optimized using Optuna and Adam optimizers, respectively. Extensive comparisons with conventional feedforward neural networks (FNNs) and long short-term memory models (LSTMs) consistently demonstrated the superiority of the KAN models, yielding up to 23% and 55% reductions in training and validation losses compared to the FNN and LSTM models, respectively, accompanied by up to 25% and 45% shorter training time and 37% and 63% lower prediction latency, respectively, together with enhanced learning stability and a more efficient, compact network architecture.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"576-596"},"PeriodicalIF":3.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11535403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148236108","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}

Effective fault diagnosis is essential for early fault detection and identification, which enables timely maintenance, reduced downtime, and efficient operation of the system. This article presents an investigation of fault signatures in online condition monitoring methods, focusing on mechanical fault diagnosis of PMSM driven systems. Angular shaft misalignment and mass unbalance faults are investigated under two different severity levels. Three axis vibration, acoustic emission, stator currents, axial and radial stray flux, and shaft torque are evaluated for fault detection, severity assessment and fault discrimination. In the first place, a theoretical framework describing the influence of the specific mechanical faults on the mechanical and electromagnetic behavior of the PMSM is established, enabling the identification of characteristic fault-related signatures. An experimental test bench is developed, integrating a PMSM with vibration, current, stray flux, acoustic emission, and torque sensors. Fault signatures are analyzed in both nominal operating condition and variable speed and load levels. Moreover, load and speed transients are investigated. Finally, to extract the most informative sensors, a data driven approach with mutual information, random forest, and Shapley additive explanations is employed. Results from this experimental investigation highlight the tradeoffs between diagnostic performance, practical implementation, and the effectiveness of combining domain knowledge with data-driven approaches for accurate, early, and cost-effective PMSM fault diagnosis.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"949-970"},"PeriodicalIF":3.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11627207","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148747038","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}

Conventional presynchronization methods based on second-order generalized integrators effectively align the fundamental voltage components but inherently reject harmonic distortion caused by nonlinear loads. As a result, a voltage mismatch between the incoming inverter and the distorted point of common coupling (PCC) may occur, leading to transient inrush currents during connection, potentially triggering protection mechanisms and compromising system reliability. This article proposes a practical and software-only control strategy for hot-swap operation under nonlinear loading conditions. The method is based on a state-dependent harmonic presynchronization mechanism that temporarily injects the PCC harmonic content into the inverter voltage reference during the synchronization stage. By forcing the incoming inverter to replicate the distorted grid waveform prior to connection, the proposed approach minimizes the instantaneous voltage gradient across the contactor. Immediately after connection, the harmonic injection is disabled, restoring standard harmonic rejection and steady-state power quality. The proposed strategy requires no additional hardware or sensors and can be implemented in existing digital control platforms. Controller-hardware-in-the-loop results at four operating points demonstrate reductions of 42.4%–60.1% in the connecting-inverter current peak. These results confirm the effectiveness and practical applicability of the method for improving hot-swap reliability in modular UPS systems and other critical power applications.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"1010-1021"},"PeriodicalIF":3.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11655535","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148836847","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}

Existing control strategies often struggle to track the complex, nonsinusoidal currents required for ripple suppression, or they rely on burdensome and inaccurate premeasured motor models. To overcome these limitations, this article proposes an integrated methodology founded on the internal model principle. The approach features two key contributions as follows. 1) A torque ripple suppression technique based on the finding that a specific current harmonic can be manipulated to minimize ripple, this harmonic is decoupled from the average torque, allowing for the independent tuning of ripple and torque. 2) A specialized current controller that achieves robust tracking of the required harmonic waveform without needing an inductance model.

While PD in sinusoidal excitations has been extensively studied with conventional detection and analysis methods, wide bandgap (WBG)-based electric drives introduce new challenges due to their high-frequency and high-speed switching. These features give rise to nonuniform voltage and charge distributions, along with voltage overshoot and ringing, governed by a geometry of PD object and drive parameters such as switching frequency and slew rate. Moreover, these fast-switching transients complicate PD detection due to electromagnetic interference (EMI). This article reviews PD characteristics in WBG-based drives, highlighting the challenges in WBG-based drives. The review explores opportunities to improve PD location prediction through voltage distribution analysis based on the impedance of PD objects, as well as to optimize insulation design by considering charge distribution and methods for reducing the electric field across the insulation. Furthermore, it discusses methods to improve the signal-to-noise ratio of PD detection, including a reduction of common-mode voltage and current with active EMI filters, thereby enhancing detection reliability in WBG-based electric drives.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"7 ","pages":"79-89"},"PeriodicalIF":3.3,"publicationDate":"2025-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11315872","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145982251","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}
