These systems are discussed in this paper with a focus on the inverter output stage. The inverters considered include conventional six- and twelve-pulse square wave, pulse-width modulated, and multi-level inverters. Current- and voltage-controlled inverters are considered where appropriate. Each of these inverter topologies has been successfully applied to a number of applications such as adjustable-speed motor drives and static VAr compensators but only limited information is available concerning the use of various topologies with active power conditioning equipment. This paper is intended to assimilate the information that is available in a convenient manner so as to provide the basis for continued research in this area.","PeriodicalId":135973,"journal":{"name":"Proceedings of 28th Southeastern Symposium on System Theory","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132634334","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 autopilot design is for angle of attack and normal acceleration tracking using a previously developed extended-mean assignment (EMA) control technique for linear time varying (LTV) systems. The EMA control technique is based on a new eigenvalue concept called series D-eigenvalue, for LTV systems. Closed-loop stability is achieved by the assignment of the extended-mean of these time-varying SD-eigenvalues to the left-half complex plane in a way similar to the eigenvalue (pole) assignment technique for linear time invariant (LTI) systems. The simulation results are for three desired command tracking case studies and are all very good.","PeriodicalId":135973,"journal":{"name":"Proceedings of 28th Southeastern Symposium on System Theory","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128443675","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}

Numerical results comparing performance of LLR and MLLR in, terms of blocking probability are introduced. As an application, the authors formulate and solve a nonlinear constrained optimization problem to calculate the load sharing coefficients that result in a maximum network rate of return for fixed levels of OD pair blocking probabilities.","PeriodicalId":135973,"journal":{"name":"Proceedings of 28th Southeastern Symposium on System Theory","volume":"22 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131859406","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}

One major obstacle for the SGML to gain more application is the prohibitively high cost of the markup process. The system the authors present adopts an incremental design approach.

The major software components of the system are described. Some selective algorithms are also introduced.","PeriodicalId":135973,"journal":{"name":"Proceedings of 28th Southeastern Symposium on System Theory","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133239583","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}
