The optimal boundary control problems for hyperbolic systems in which integral time lags appear in the Neumann boundary conditions are solved. Such systems constitute, in a linear approximation, a universal mathematical model for many processes in which transmission signals at a certain distance with electric, hydraulic and other long lines take place. The time horizon is fixed. Making use of Dubovicki-Milyutin scheme, necessary and sufficient conditions of optimality for the Neumann problem with the quadratic performance functionals and constrained control are derived.","PeriodicalId":383231,"journal":{"name":"Pomiary Automatyka Robotyka","volume":" 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electromagnetic actuator was installed in the timing system of a single-cylinder internal combustion engine, which forced its basic design parameters in terms of force and frequency of operation. For the electromagnetic actuator in question, field calculations of the esign variants of the linear electromagnetic actuator for two types of materials were conducted. The finite element method was applied to the computer-aided design of electromagnetic actuators. The influence of the magnetic circuit and the dimensions of the windings on the distribution of the magnetic field were analyzed. The thickness and height of the magnetic field induces, and the dimensions of the stator poles have been changed while maintaining the same external dimensions of the actuator for design reasons. All this work was aimed at improving the performance of the internal combustion engine in terms of improving efficiency in terms of partial engine loads. In this area, the internal combustion engine is characterized by low efficiency, significantly deviating from the maximum, and at the same time, during normal operation of vehicles is the area most often exploited.","PeriodicalId":383231,"journal":{"name":"Pomiary Automatyka Robotyka","volume":" 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Power Loss and Temperature Distribution in Coil of PFC Inductor with Air Gap for Multimode Operation 多模运行时带有气隙的 PFC 电感器线圈中的功率损耗和温度分布

{"title":"Power Loss and Temperature Distribution in Coil of PFC Inductor with Air Gap for Multimode Operation","authors":"R. Kasikowski","doi":"10.14313/par_251/89","DOIUrl":"https://doi.org/10.14313/par_251/89","url":null,"abstract":"Power converters inherently display non-linear load characteristics, resulting in a high level of mains harmonics, and hence the necessity of implementing Power Factor Correction (PFC). Active PFC circuitry typically comprises an inductor and a power switch to control and alter the input current so that it matches, in shape and phase, the input voltage. This modelling of the waveforms can be performed by means of distinct conduction modes of the PFC inductor. The digital controller implemented in the constructed and investigated boost-type PFC converter can be programmed to operate in discontinuous conduction mode (DCM), continuous conduction mode (CCM), or a combination of the two. The individual modes of operation, via distinct PFC inductor current waveforms, impact the overall efficiency of power conversion and, by extension, temperature distribution in the magnetic component. This paper investigates how the examined conduction modes bear on distinct power-loss mechanisms present in the PFC inductor, including high-frequency eddy-current-generating phenomena, and the fringing effect in particular. As demonstrated herein, the DCM operation, for the set output power level, exhibits exacerbated power dissipation in the winding of the inductor due to the somewhat increased RSM value of the current and the intensified fringing magnetic flux at an air gap. The latter assertion will undergo further, more quantitatively focused research. Finally, the construction of the coil was optimised to reduce power loss by diminishing eddy-current mechanisms.","PeriodicalId":383231,"journal":{"name":"Pomiary Automatyka Robotyka","volume":" 60","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
