In the proposed work, two 2-level inverters are used on either side of OEWIM drive to obtain the three-level output voltage. To generate the control signals for the two inverters, NSHCPWM technique is used. In the proposed method reference vector is realized with two components, based on the tip of the reference vector location nearest sub-hexagonal centre is identified, which is one of the switching vector used to generate the control signals for inverter-I and the other component is realized using inverter-II by mapping into the inner sub-hexagon. So that one inverter is used as switching inverter and the other is as clamping inverter. Ripples in torque and stator current are also reduced in the proposed work over conventional SVPWM techniques. Proposed work is analyzed theoretically and the same can be realized using MATLAB/SIMULINK and the corresponding results are presented for different modulation index.","PeriodicalId":31657,"journal":{"name":"Acta Electrotechnica et Informatica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43457838","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}

We consider the case where redundant hydraulic pipelines are chosen to achieve a desirable level of reliability. The hydraulic pipelines of the system are characterized by their cost, capacity and reliability. The reliability is defined as the ability to satisfy the water consumer demand which is represented as a piecewise cumulative load curve. The proposed meta-heuristic seeks for the optimal configuration of series-parallel systems in which a multiple choice of hydraulic pipelines are allowed from a list of product available in the hydraulic market. Our approach has the advantage to allow hydraulic pipelines elements with different parameters to be allocated in hydraulic systems. To allow fast reliability estimation, a universal generating function method is applied.","PeriodicalId":31657,"journal":{"name":"Acta Electrotechnica et Informatica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43187301","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}

It theoretically characterizes the experimental identification of a system and the choice and classification of identification methods. It also describes chosen methods of experimental identification (deterministic methods, neural networks) in details. A proposal of an application consisting of a user interface and a generated model scheme are also mentioned. The testing results on data from a small turbojet engine MPM-20 are shown. Based on the comparison of real measured values and output values of the model the application evaluates the accuracy of each of the identification methods. The main contribution of the proposed application is an automatization and simplification of the experimental identification process in MATLAB.","PeriodicalId":31657,"journal":{"name":"Acta Electrotechnica et Informatica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42548653","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}
