To address the challenges of fault feature extraction, this article proposes an end-to-end diagnostic approach based on a wavelet kernel convolutional neural network (WKCNN), capable of extracting multi-scale features from current signals to significantly enhance diagnostic accuracy. This method directly uses raw three-phase current signals as input, applying wavelet kernel convolution to automatically capture frequency-domain fault features, combined with a Softmax classifier optimized by the Adam algorithm to achieve fault diagnosis for NPC three-level inverters. Experimental results under various operating conditions demonstrate that this approach maintains robust diagnostic accuracy across multiple fault scenarios, with comparative analysis further confirming its advantages in diagnostic efficiency and performance over traditional machine learning and other deep learning methods.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 2","pages":"234-245"},"PeriodicalIF":0.0,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11014611","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536328","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 existence of additional magnetic field is proved by the simulation models under two boundary conditions, and its characteristics and source are analyzed. The analytical model is established, and the influence of key parameters on the additional magnetic field is discussed. On this basis, the influence of the additional magnetic field on the electromagnetic torque of the motor is studied, and the analytical expression of the additional torque is constructed.

Various robust control methods have been developed to mitigate or eliminate the effects of these uncertainties. However, the robustness to uncertainties of electrical drive systems has not been clearly defined. No systemic procedures have been proposed to evaluate a control system's robustness (how robust it is). This paper proposes a systemic method for evaluating control systems' robustness to uncertainties. The concept and fundamental theory of robust control are illustrated by considering a simple uncertain feedback control system. The effects of uncertainties on the control performance and stability are analyzed and discussed. The concept of design for six-sigma (a robust design method) is employed to numerically evaluate the robustness levels of control systems. To show the effectiveness of the proposed robustness evaluation method, case studies are conducted for second-order systems, DC motor drive systems, and PMSM drive systems. Besides the conventional predictive control of PMSM drive, three different robust predictive control methods are evaluated in terms of two different parametric uncertainty ranges and three application requirements against parametric uncertainties.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 2","pages":"131-145"},"PeriodicalIF":0.0,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11014606","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144536370","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}

Standard copper magnetic wire and low-carbon steel laminations are used to construct SRMs, which give them high efficiency in the range of 85–95%. Despite SRM's desirable features over traditional motor-speed drives, high torque ripples and radial distortions constrain their deployment in EVs. Precise rotor position is imperative for effective management of the speed and torque of SRMs. This paper provides an illustrative compendium on review of the torque-speed control and ripple mitigation techniques using design enhancements and control methods for SRM drives for EV applications. The various schemes were evaluated on their performance metrics-operational speed range, control complexity, practical realization, need for pre-stored parameters (lookup tables of current, inductance and torque profiles) and motor controller memory requirements. The findings provide valuable insights into balancing the gains and tradeoffs associated with EV applications. Furthermore, they pinpoint opportunities for enhancement by analyzing the cost and technical aspects of different SRM controllers.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 1","pages":"46-75"},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10932740","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748752","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}

In this study, a double-sided linear induction motor (LIM) with 500 W of output power, 60 N of thrust force and 200 V/38.58 Hz of supply voltage was designed to be used in hyperloop development competition hosted by the scientific and technological research council of turkey (TÜBİTAK) rail transportation technologies institute (RUTE). In contrast to the studies in the literature, concentrated winding is preferred instead of distributed winding due to mechanical constraints. The electromagnetic design of LIM, whose mechanical and electrical requirements were determined considering the hyperloop development competition, was carried out by following certain steps. Then, the designed model was simulated and analyzed by finite element method (FEM), and the necessary optimizations have been performed to improve the motor characteristics. By examining the final model, the applicability of the concentrated winding type LIM for hyperloop technology has been investigated. Besides, the effects of primary material, railway material, and mechanical air-gap length on LIM performance were also investigated. In the practical phase of the study, the designed LIM has been prototyped and tested.

In order to realize the requirements of high-precision and fast-response control of permanent magnet synchronous motor (PMSM) under large inertia load, an improved feedforward control strategy based on position impulse compensation and PD iterative algorithm is proposed to improve the response speed of the PMSM servo system and reduce the overshoot oscillation. This paper analyzes the mathematical models of the speed servo system and position servo system of the PMSM, calculates position overshoot impulse of the PMSM servo system, and improves the traditional feedforward control strategy to reversely compensate when the position is about to overshoot. Moreover, in order to further reduce the position overshoot, the PD iterative control algorithm is superimposed without increasing the complexity of the algorithm. The input signal is continuously corrected through multiple runs to achieve a smoother response control. The effectiveness of the proposed feedforward control strategy is verified by simulation and experiment.","PeriodicalId":100229,"journal":{"name":"CES Transactions on Electrical Machines and Systems","volume":"9 1","pages":"100-109"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10946688","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748776","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}
