At the same time, the control and modulation of MLIs are especially challenging due to the high number of switching states, many of them redundant in terms of output voltage generation, and their nonlinear characteristics. In order to ease their implementation in real environment, model predictive control (MPC) is often considered, where the main control targets are: 1) to generate a the desired output current and 2) to keep the internal converter capacitor voltages at their reference value. However, a major issue with the implementation of MPC in MLIs is that the number of calculations to be done online increases dramatically with the number of levels, making it almost impossible to apply MPC in some practical cases. For these reasons, one of the main research trend in MPC for MLIs is to provide an algorithm which can reduce the computational burden necessary to operate the control. The article proposes a review of such control techniques. Starting from the basic MPC implementation and using a flying capacitor converter as an example the article review the basic strategies to avoid calculating the weighting factor in the cost function, simplifying the implementation. Also, methods to reduce the number of calculations necessary to implement MPC are shown and applied to cascaded H-bridge converters. These techniques allow to keep an high load current quality while reducing more than 95% in the number of calculations necessary to implement the control. Finally, other operation improvements of MPC are also included, such as fixed switching frequency operation and multistep MPC, reaching an important performance improvement compared to the basic MPC strategy.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"428-441"},"PeriodicalIF":7.9,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10679905","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142253442","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 downside of a permanent magnet machine is the inability to regulate the rotor field, creating nonideal behavior during high-speed or low-load operation, and potentially resulting in high currents and voltages in fault conditions. Several solutions to this have been explored, such as interior permanent magnet (combined reluctance and permanent magnet rotors), “hybrid” wound field and permanent magnet rotors, and variable flux machines with in-situ magnetization control or mechanical field weakening. This article proposes a novel method of regulating the air gap in axial flux machines, allowing for a low-cost mechanism allowing two degree of freedom operation without additional power electronics or modifications to the magnetics. The proposed method uses stacked linear springs to create a nonlinear bias against the attraction force, and then leverages direct axis current to control the air gap. The ideal constant current optimized field weakening spring curve is presented and the proposed concept is experimentally validated on a single-stator single-rotor axial flux machine.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"369-380"},"PeriodicalIF":7.9,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10670564","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142165099","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}

A suitable test bed has been properly manufactured to perform the experimental campaign for the evaluation of the benefits and to deploy a dedicated management procedure of the two-phase cooling. The system is tested under real operating conditions, in which the system is employed for cooling a 1200-V 100-A insulated-gate bipolar transistor (IGBT) power module of an inverter controlling a permanent magnet synchronous machine. The experimental results show the inverter temperature behavior in start-up for different flow rates of coolant and different temperatures of the fluid on the secondary system. In the steady-state operation, using lower coolant flow rates in the primary circuit achieved equal or even better cooling for the IGBT module compared with higher flow rates. With respect to traditional cooling approaches, the proposed arrangement allows a greater extraction of the heat at a very low flow rate of the cooling fluid, even with standard industrial grade heat sinks, which motivates the use of this cooling technology for the next generation of power electronics converters.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"381-390"},"PeriodicalIF":7.9,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10663977","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142176890","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}

However, control techniques can be designed and optimized to lessen this issue. In this context, this article proposes the optimization of analytical torque sharing functions (TSFs) for dc-link current reduction in SRMs. Initially, the analytical TSFs are described, and the importance of adequate parameter selection is highlighted. Next, an optimization procedure based on the nondominated sorting genetic algorithm II is proposed to determine the optimal turn-\u0000<sc>on</small>\u0000 and overlap angles by solving a multiobjective optimization problem considering torque rms error and dc-link rms current as objectives to be minimized, something not previously reported in the literature. The pareto fronts for different operating conditions are presented, including both soft and hard chopping operation, as well as different sampling frequencies. Then, an approach for selecting a solution from within the pareto front is described, enabling the result from the pareto front that yielded the desired tradeoff between torque RMSE and dc-link current to be identified. Experimental results are provided to support the effectiveness of the proposal. A comparison between three different cases is shown, highlighting the tradeoff between objectives.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"356-368"},"PeriodicalIF":7.9,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10633794","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142013335","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}

Flattening the radial-force sum eliminates the multiples of the third radial-force component. These components excite the breathing mode vibration, which is typically the dominant vibration in switched reluctance motors with a high number of poles. The previously proposed analytical current derivation for flattening the radial-force sum neglects magnetic saturation, limiting its applicability to low-torque region. Consequently, for high-torque saturation conditions, the previous waveform shaping degrades in flattening the radial-force sum. The proposed refinement of the analytical current waveform addresses this limitation, enabling effective radial-force sum flattening even under high-torque conditions. Additionally, the proposed current exhibits significantly lower peaks than those of the flattening methods at high-torque region in the literature, mitigating the need for higher-rated inverters. Finite element analysis and experimental validation verify the effectiveness of the proposed method.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"325-337"},"PeriodicalIF":7.9,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10613515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868156","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 proposed control method named multiparallel vector current control is a variant of virtual synchronous machine (VSM) applied to the multiparallel inverter system (MPIS). It takes on the good qualities of VSM control, such as offering inertia, voltage support, the ability to operate in standalone mode, and strong performance in weaker grids. Moreover, this concept boasts swift current set-point tracking abilities and enhanced synchronization properties. Integration of the P2G system involves an MPIS that transforms ac power from renewable sources into usable dc power, along with an electrolysis device. The later utilizes dc power source to generate hydrogen and oxygen by decomposing water. This integration strategically prevents grid-induced overvoltage or undervoltage from affecting the electrolysis device. This protects it from malfunctions or damage while keeping the voltage and frequency within the normal range. The efficacy of the proposed control method is rigorously substantiated through analytical models, time-domain simulations, and experimental validation in real-world applications. This comprehensive validation process underscores its viability and robustness in ensuring grid stability while facilitating efficient P2G conversion operations.","PeriodicalId":100629,"journal":{"name":"IEEE Open Journal of Industry Applications","volume":"5 ","pages":"311-324"},"PeriodicalIF":7.9,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10601332","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141746211","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}
