A laser beam is aligned when the direction of propagation passes through two points defined in irises planes $(mathrm{O}_{1}(mathrm{x}1, mathrm{y}_{1}), mathrm{O}_{2}(mathrm{x}2, mathrm{y}_{2}))$, separated by an arbitrary distance, and having the same height from the working plane (Oi(yi) $=mathrm{O}_{2}(mathrm{y}_{2})$). The method of automatic laser beam alignment is based on detection of changes in position by using a CCD camera and automatic repositioning. By integrating actuators in the kinematic mounts, is achieved the automatic orientation of the beam through the center of two coordinates defined by the references Oi and O2. The coordinates of points Oi and O2 in the alignment system are sent to the CCD camera by generating two reflections using laser beam splitters. The position changes detected by the CCD camera are processed by the controller and converted into control pulses for the execution elements that perform the automatic orientation of the beam through the points O1, O2.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129614044","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}

Since PMSMs exhibit relatively nonlinear behavior and their parameter values are critical, they necessitate more robust control and parameter estimation than conventional control methods. Parameters of the PMSMs are subject to abrupt changes in load and temperature. These parameter fluctuations significantly affect the stability of the system. Therefore, in this study, beside the effective control of the system, an efficient parameter estimation has been established in the MATLAB/Simulink environment by RKMPC. The control and parameter estimation capability of RKMPC has been proven by simulation results.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129751449","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}

For electric vehicle control, one of the control structures applied to MMS will be applied based on torque control. The present work contributes to the development of a new control structure for an electric vehicle (EV) equipped with two sets of bi-interior permanent magnet synchronous motor (IPMS) in-wheel motors (IWM) connected in parallel and supplied by a single three-phase three-level NPC inverter, one set on the left longitudinal side and one on the right longitudinal side. In order to produce the corresponding torque to the driving wheels according to the driver’s steering, acceleration or braking commands, each set is controlled by a proposed fuzzy direct torque control using PSO algorithm. The proposed control structure, adapted on the basis of a “master-slave” control structure, was implemented and tested in simulation to analyze its robustness under mechanical and electrical disturbances.

Their surfaces are often found with non_ideal surface morphology affected by wind erosion and/or dirt accumulation. To reduce corona discharge of these grading rings operated online, two anti-corona schemes, grinding and RTV(Room Temperature Vulcanized Silicone Rubber) coating, are proposed. Through analyzing the simulation results, it is found that the two schemes can improve the surface electric field to achieve the purpose of anti-corona. After comparing the two schemes, RTV coating scheme shows more obvious to reduce the maximum electric field intensity of the surface than the grinding scheme, and RTV coating is easier than grinding to be implemented in engineering practice.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115942936","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 paper aims to assess these influences of thermal conditions on the performances of a piezoelectric harvester, using Finite Element Method simulations. The material of the piezoelectric wafers is PZT-5H (soft lead zirconate titanate), with improved performances for energy harvesting over other materials. In spite of its improved piezoelectric effect, this one can be less stable with temperature variations. Before harnessing the vibrations of any equipment subjected to important thermal effects during operation, temperature has to be measured in the mounting spot. The temperature, here, is $-30^{circ}mathrm{C}$ to $100^{circ}mathrm{C}$. The paper aims to assess how the working temperature of the targeted machinery influences the response of the harvester.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121580904","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}
