In this paper the AIS technique has been suitably applied to develop a new model for efficient identification of nonlinear dynamic system. Simulation study of few benchmark identification problems is carried out to show superior performance of the proposed model over the standard multilayer perceptron (MLP) approach in terms of response matching, number of training samples used and convergence speed achieved. Thus it is concluded that the AIS based model used is a preferred candidate for identification of nonlinear dynamic system.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130359436","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}

Magnetic levitation (Maglev) systems offer many advantages such as frictionless, low noise, the ability to operate in high vacuum environments and so on. Reliable and robust controller synthesis of this system is of great practical interest. Robustness is a key issue in designing a control system for a magnetic levitation as the models are never 100 percent accurate and the uncertainties in the model must be accounted. In the present work, a new approach using quantitative feedback theory (QFT) is presented for design of a robust two degree of freedom controller for magnetic levitation. Experimental tests are conducted to check the reliability and robustness of the designed control system by subjecting it to disturbances. The experimental test results show the control system design to be reliable and robust.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115745526","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 has been observed that the available analytic expressions involve integration in infinite limit. The expressions containing such kind of integrals have been meticulously transformed into finite range equations. In soft handoff, probability of outage, number of base stations (BS) in the active set, and number of active set updates are some of the performance metrics commonly considered. Accurate closed forms for all these performance indicators have been proposed which simplifies the calculation of several other metrics entailing them. Moreover, the underlying system model takes into account of more than two BS (specifically three) extending the traditional two BS model towards more complex but realistic characterization of soft handoff performance analysis framework.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121545763","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 proposed controller is used to control the voltage and frequency through control of active power at the generator terminal independently. The decoupled controller is a combination of a static compensator (STATCOM) consisting VSC with zig-zag transformer for regulating the voltage and an electronic load controller (ELC) for controlling the active power which in turn controls the system frequency constant. The STATCOM is realized using IGBT (Insulated Gate Bipolar Junction Transistor) based current controlled voltage source converter (CC-VSC) and a self supporting DC bus, while ELC consists of 3-phase diode rectifier, chopper switch and auxilliary load. The proposed generating system is modeled and simulated in MATLAB along-with Simulink and PSB (Power System Blockset) toolboxes. The simulated results are presented to demonstrate the capability of generating system for feeding 3-phase 4-wire loads.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"308 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127565332","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}
