This paper introduces a novel adaptive SMO for permanent magnet synchronous motor (PMSM) drive, facilitating sensorless speed and position estimation. To reduce chattering effect, an adaptive gain-based sigmoid function is used as a switching function. In addition to this, harmonics contain, and DC offset from estimated back-EMF are reduced by employing mixed order generalized integrator (MOGI) as prefilter. To extract rotor speed and position and to mitigate harmonics arising from inverter nonlinearities, an improved quadrature phase locked loop (IQPLL) is utilized. This approach enhances QPLL estimation performance without compromising bandwidth or introducing phase delays typically associated with conventional QPLLs as well as achieving selective harmonics cancellation. Collective findings demonstrate effectiveness of proposed methodology in enhancing speed and position estimation accuracy while addressing inherent challenges associated with conventional techniques. Overall sensorless SPMSM performance is supported by obtained results.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"60 6","pages":"9100-9110"},"PeriodicalIF":4.2,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three types of spray-charge measurement methods are described where current drawn from the droplet cloud was measured by: ionizing probe; direct impingement of spray onto a conductive plate; and spray directed into an isolated tunnel comprised of a series of conductive impaction screens. The latter method was refined for long-duration spray current measurements necessary for evaluating spray charging consistency with highly conductive liquids, including disinfectants. Additionally, a spray-deposition evaluation method is described which utilizes an ungrounded target array sprayed with an inert, insoluble fluorescent tracer incorporated into the water-based disinfectant or a concentration of salt water that matches the conductivity of disinfectant. Using the fluorometric method, the mass transfer onto target coupons placed on each of the four sides of square wood posts was quantified to evaluate the ability of an electrostatic sprayer to deposit droplets onto the sides and backsides of target surfaces. Several commercial models of electrostatic sprayers based upon fundamentally different principles of atomization and droplet charging (e.g., air-atomizing induction-charging and hydraulic-atomizing conduction-charging) were evaluated for spray charge, spray deposition, and performance consistency using the described methods with liquids of high electrical conductivity. Air-atomizing induction-charging (AAIC) electrostatic spray systems exhibiting charge-to-mass levels above 1 mC/kg achieved significant spray deposition improvements to target surfaces out of the direct line-of-sight compared to uncharged spray and spray devices exhibiting low droplet charge.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"60 6","pages":"8371-8382"},"PeriodicalIF":4.2,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Machine learning algorithms are widely used for prediction and decision-making processes due to the growing presence of optimized statistical models based on training datasets, that are far superior to conventional computational statistical methods. In this work, a temperature dataset has been generated in real-time from an IoT and temperature sensor-based hardware, clipped-on the casing of a vehicle, pre-possessed and fitted into optimized models so that future values of temperature can be accurately predicted using different supervised regression machine learning algorithms. The predicted temperatures have been compared with the actual recorded temperatures and a statistical error analysis has been done to compare the results based on the Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), R-Square (R\u0000<sup>2</sup>\u0000) and adjusted R\u0000<sup>2</sup>\u0000 Score. The advantage of this methodology is that it is independent of system parameters, and that any future values of critically high temperature may be predicted before they occur, so that drivers can be alerted and take corrective measures before actual damage takes place. This methodology may be applied to prevent incidents of fire in EV batteries, energy wastage due to high temperatures during charging or normal running, and to enhance passenger comfort.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"60 6","pages":"9251-9259"},"PeriodicalIF":4.2,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142226919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of current harmonics on the ECL is further evaluated using the finite element method, based on which a simplified prediction model with only two coefficients for the evaluation of ECL in PMSMs is proposed. Finally, an efficient semi-analytical synthesis method based on a limited number of finite element cases has been proposed to consider the impact of high-frequency current harmonics on the ECL.

This paper presents a trade-off analysis of different resilience-based active distribution system upgrade solutions, specifically to mitigate the outage risks of high-speed wind events. The resilience planning problem for unbalanced three-phase distribution systems is formulated as a two-stage risk-averse stochastic optimization model with conditional value-at-risk (CVaR) as the risk measure. The possible planning measures include installing grid-forming distributed generators (DGs) capable of islanded operation, installing remote-controlled tie-switches, and implementing line hardening solutions. Realistic wind data and fragility models are adopted to simulate high-speed wind event scenarios. The parameters used in this work for trade-off analysis are fragility models, risk preference, multiple planning resources, and planning budget allocation. The proposed approach is validated on a modified IEEE-123 bus test case. The analysis presented in this work can inform system operators about the trade-offs in optimal planning budget and resource allocation, ultimately enhancing the resilience of the distribution grid.","PeriodicalId":13337,"journal":{"name":"IEEE Transactions on Industry Applications","volume":"60 6","pages":"8031-8043"},"PeriodicalIF":4.2,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, concerns arise from the adverse effects of space harmonics introduced by the rich armature winding magnetomotive force (MMF). To reduce the space harmonics of armature winding MMF, a Two-terminal Hybrid Connection Method (TTHCM) of fractional slot electrical machine is proposed. Firstly, the general principle of harmonic elimination is derived, outlining the specific armature MMF harmonic orders that TTHCM can eliminate under different pole-slot combinations. Taking the example of a machine with 24-slot/10-pole configuration, the analysis process is presented. And the harmonic orders eliminated include the 1st, 7th, 11th, 13th, 17th, 23rd, and 25th space harmonics of the armature MMF. Next, models for a conventional three-phase machine, star-delta, dual three-phase, and TTHCM are established and compared. It is demonstrated that, compared to the dual three-phase connection, the TTHCM can enhance the torque, reduce torque ripple, decrease permanent magnet eddy current loss, and improve vibration performance without increasing the complexity of the control system. Finally, a prototype of TTHCM machine is manufactured and tested.
