The VSG algorithm enables power converters to support the grid in case of voltage dips by injecting a large short-circuit current. However, a current limitation strategy must be implemented to address the hardware limitation of power converters. As demonstrated in the literature, the current constraint affects the VSG’s dynamics by limiting the output power, thus causing a substantial acceleration of the virtual rotor and potentially leading to a loss of synchronism. Several available solutions utilize the measured actual active power as feedback, thereby modifying the VSG with complex control algorithms. On the other hand, this article proposes a different approach, highlighting the benefits of using the virtual power instead of the measured power feedback for the most adopted limitation strategies available in the literature. This paradigm shift leads to a significant improvement in stability without requiring fault detection capability or switching the control structure, as demonstrated both theoretically and experimentally in this article.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"6 ","pages":"490-505"},"PeriodicalIF":7.9,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11072272","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144671234","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 article offers a systematic method for accurately calibrating the electromagnetic FEA models, permitting to consider the production process within the motor design stage. A synchronous reluctance motor prototype is designed, manufactured, and experimentally characterized, and the measured flux and torque characteristics are exploited for ex-post calibrating the FEA model of the machine. This approach led to a reduction in torque estimation error from 18% to 4%, and an improvement of the flux maps evaluation, thus enhancing and validating the design procedure and permitting further optimization steps of machines with similar geometry and dimensions. The effects are particularly evident in the proposed motor due to the reduced size of the rotor flux barriers, stator teeth, and yoke. The mechanical tolerances are analyzed through a Monte Carlo analysis covering different areas of the machine.

Each joint typically incorporates a motor and a gear to drive its motion. Power delivery and control for these joints are usually achieved through cables for power and data transfer, which are routed through the joints. However, as the joints move, these cables bend and flex, leading to eventual failure due to the limited number of bending cycles they can withstand. In addition, in high-precision joints, cable slack can disrupt position control accuracy. To address these challenges, this article investigates wireless power and data transfer for robotic joints. The proposed approach leverages a closed magnetic core for power transfer, minimizing stray magnetic fields, and uses photodiode-based communication with a custom-developed control circuit. The approach is validated through experimental measurements and benchmarked against existing solutions in the literature. We demonstrate a system capable of transferring 200 W of power and achieving a data transfer rate of 2 Mbit/s, with the total weight of all components being 96 g.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"6 ","pages":"525-538"},"PeriodicalIF":7.9,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11068112","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144680766","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}

The knowledge of grid impedance is required to exploit properly the VSM features in providing grid ancillary services, such as inertial behavior, harmonics compensation, as well as short-circuit current injection during faults. Therefore, this article proposes a closed-loop grid impedance estimator, specifically designed for VSM applications, which is directly integrated into the VSM model. The grid resistance and inductance estimations are performed in real time, without the need of data elaboration through complex mathematical tools, which are usually required by methods available in the literature. The proposed solution leverages the VSM dependency on grid parameters when an amount of current is directly injected into the grid without being processed by the VSM itself. The proposed estimator inherently rejects the noise on voltage and current measurements, thus providing reliable results for real world operating conditions affected by disturbances. It can be easily tuned according to the desired filtering capability and estimation process duration. Experimental tests on a 15 kVA grid-tied inverter validate the proposed solution.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"6 ","pages":"427-444"},"PeriodicalIF":7.9,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11059323","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144597892","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}

Then, using evolutionary optimization, provides potential design options for meeting the performance criteria defined by the designer, in terms of output power and efficiency. Unlike the solutions available in the literature, the proposed technique allows the component tolerances to be considered. In fact, the tool implements an automatic Monte Carlo analysis to estimate the probability that a specific solution will achieve the expected performance levels, given the fabrication tolerance of the components. This represents valuable information for mass production, as WPT systems are typically very sensitive to component variations. Besides presenting the toolbox and its functionalities, this article also reports the extensive experimentation that the authors conducted on WPT systems, designed using MatWPT.

Traditionally validated for industrial motors, the STTT procedure involves a brief dc excitation with motor phases connected in series, followed by analysis using a first-order lumped parameter thermal network. However, for traction motor drives where phase terminals may be inaccessible, the standard all-in-series STTT procedure is not feasible. Moreover, in such highly loaded traction motors, the estimated thermal parameters are sensitive to dc excitation duration, making the first-order STTT model unsuitable. This article presents an STTT model of higher order along with an optimized testing sequence and data processing approach, extending the applicability of this method to traction and high-power-density motors. Experimental validation on two commercial supercar traction motors demonstrates the effectiveness of the proposed model and procedure, to be considered an upgrade of wider and more general validity of the existing first-order STTT method.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"6 ","pages":"391-402"},"PeriodicalIF":7.9,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11037247","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144524413","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}
