Instead of the traditional state-space model, the proposal makes use of a convex exact rewriting of the nonlinear model in its descriptor form, which naturally arises in Lagrange-Euler dynamics. Convexity proves to be useful when combined with an extension of the direct Lyapunov method for singular systems, since it leads to design conditions in the form of linear matrix inequalities, which allow the use of convex programming techniques. Moreover, real-time implementation issues such as actuator saturation limits and decay rate are straightforwardly incorporated in the design. Numerical advantages of the descriptor convex model over the state-space representation are also discussed.","PeriodicalId":285464,"journal":{"name":"2016 13th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129625655","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}

Developed DMS and control architecture utilizes a FPGA (Field Programmable Gate Array) device allowing electrical feeder control. This DMS and control architecture in its case study gives priority to control a voltage regulator, based on the switching TAP change (for each phase). The test case system used in this research consists of a 959 nodes distribution feeder, considering a typical real Brazilian electrical-distribution radial system. Some results for the distribution feeder test case are presented, in order to demonstrate the feasibility of the developed higher-level control using a FPGA device in a VHDL platform.","PeriodicalId":285464,"journal":{"name":"2016 13th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125369996","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}
