The “non-nominal” modes are most often characterized by lower efficiency and higher ripples and are undesired. That leads us to the search of the strategies to control those nonlinear phenomena. Our proposal is based on transferring the system to a monostable behavior utilizing a periodic modulation of a carrier signal. The applicability of the proposed control and the suitable ranges of the modulation strength are studied using the bifurcation diagram. In addition, if the control should provide a return to an uncontrolled state after the control goal is achieved, we demonstrate that an implementation should include smooth attenuation of the modulation strength to ensure the “nominal” operation after the control is disabled.","PeriodicalId":244144,"journal":{"name":"2022 IEEE 4th International Conference on Modern Electrical and Energy System (MEES)","volume":"252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124450262","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}

In this work, Zeta-SEPIC DC-DC converter configuration is considered, which has a number of important advantages for electric drives of autonomous vehicles. The operation of this converter is described by two systems of nonlinear equations - respectively for the forward power transfer (FPT) and backward power transfer (BPT) modes. To develop a control system for such an object, the energy approach - passivity-based control (PBC) is applied. In particular, thanks to mode decomposition, two PBC subsystems were synthesized for FPT and BPT, respectively. A number of control system configurations were studied by means of computer simulation, among which the most effective ones were selected for each of the modes. In order to stabilize the static and dynamic indicators of the system, nonlinear dependencies of additionally introduced coefficients of interconnections were found, the effectiveness of which was confirmed by the simulation results.","PeriodicalId":244144,"journal":{"name":"2022 IEEE 4th International Conference on Modern Electrical and Energy System (MEES)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123038487","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}

Studies have confirmed that, in addition to technical and information issues, distance education is complicated by the level of training of specialists, which affects the level of the necessary knowledge required for effective realisation of educational projects. Insufficient level of mastery of project-based methodological tools for distance learning, lack of willingness to implement IT innovations for educational content systematisation, and the educational space organisation are often the reasons that don't let Higher Education Institutions (HEI) expand e-learning profitability. In order to increase the level of compliance of the educational process with the needs of students and the educational services market, it is necessary to constantly modernize the learning process. For this, it is necessary to constantly test new educational formats, gamify the educational process, in particular, implement project-based distance learning by implementing modern information technologies.","PeriodicalId":244144,"journal":{"name":"2022 IEEE 4th International Conference on Modern Electrical and Energy System (MEES)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128647686","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}

This method of stabilization is only applicable for conditions of constant frequency operation which are generally fans or machines used for pumping. The purpose of this system is stabilization of induction motor during voltage disturbances without impact on load. For our consideration the 3-ph induction motor is induced with single line voltage sag and the stabilization is achieved using different controller schemes.

It is argued that the main goal of enterprise management in the conditions of digital transformations is the formation of internal motivation among employees. As a result of this, the employee's dependence on positive and negative reinforcements from management decreases and self-motivation increases. The internal and external factors that contribute to the increase or decrease of the salary are determined. The role of the obtained results in further practical implementation is to make clear how AI algorithms help employees reach goals more efficiently - based on the study of cases of digitalization achievements in the field of motivation on the example of Ukrainian innovative companies the construction of the “needs - interests - incentives (motives) - result” scheme was proposed. Direct economic, indirect economic and non-monetary methods of motivation are considered and the main principles of the development of the motivation system are highlighted. It is emphasized that due to the training and retraining of personnel in such a way that the growth of their wages does not lag behind their productivity, and they receive wider opportunities for career growth, it is possible to ensure the sustainability of personnel policy in the conditions of the transformational impact of digitalization and AI.","PeriodicalId":244144,"journal":{"name":"2022 IEEE 4th International Conference on Modern Electrical and Energy System (MEES)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127270235","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}

While decision-making engine for single robot includes the problem- solver and operator schemes for actions, the decision-making for two robots will be defined by decision-making possibilities of each robot and role of robot in group. Here, the behavior of robot in a group will depend on technical specifications and ability to execute tasks of robotic team, of subordination and relations inside group, of workspace states specifications.

Analysis of the forecast and actual generation data showed that the actual annual deviation from the forecast ranged from +5.47% to −5.24%, which is slightly higher than the annual generation variability of 4.87% determined by PV-GIS. The economic performance of a solar power plant is affected by the accuracy of forecasting hourly generation a day in advance. In order to improve the accuracy of forecasting the hourly generation of the SPP, an analysis of data from the guaranteed buyer, who buys all the generated electricity, and the plant's SmartLogger1000 monitoring system was performed. According to the results of the analysis, it was found that there is a difference in the data of the guaranteed buyer and the monitoring system, which arose as a result of the non-synchronization of the SmartLogger1000 monitoring system with the guaranteed buyer. The analysis of the hourly forecasts of the guaranteed buyer and the forecasting service showed that the sum of the hourly deviations of the forecast of the SPP service from the actual generation for December 2022 was 71.4%, and the sum of the hourly deviations of the forecast of the guaranteed buyer was 117.9%.
