An improved observer model is developed based on a reference flux model and a closed-loop Gopinath model flux observer which combines current and voltage model flux observers. The d-axis reference flux linkage of the indirect field oriented control is provided by flux weakening method. Furthermore, a proportional-integral (PI) based flux controller is used to provide the compensation for the reference flux model by comparing the flux reference and the observed flux from Gopinath model flux observer. An improved self-tuned NFC is utilized as a speed controller for IM drive. The proposed NFC incorporates fuzzy logic laws with a five-layer artificial neural network (ANN) scheme. In the proposed NFC, parameters of the 4th layer are tuning online for the purpose of minimizing the square of the error. Furthermore, the design of normalized inputs makes the proposed NFC suitable for variant size of IM with a little adjusting. A complete simulation model for indirect field oriented control of IM incorporating the proposed MRAF observer based NFC is developed in Matlab/Simulink. The performances of the proposed IM drive is investigated extensively at different dynamic operating conditions such as step change in load, step change in change in speed, parameter variations, etc. The proposed IM drive is also implemented in real-time using DSP board DS1104 for a laboratory 1 HP IM. The performance of the proposed MRAF observer based NFC controller is found robust and potential candidate for high performance industrial drive applications.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115848805","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}

Power oscillations and voltage recovery performance after some contingencies are recognized as typical issues on customer's systems. The strong nonlinearity caused by the complicated system configuration falls into difficulties of the proper evaluation of the transient state. Power system analysis is an effective countermeasure for these issues, however, there are some problems on the modeling of each component for better assessment of inherent phenomena. In this paper, required models especially for the complicated governor system for the assessment of the dynamical process are discussed. These models are consistently implemented on the MATLAB/Simulink environment with object oriented configuration. Static and dynamic characteristics of the real power system of a petrochemical plant are investigated as an example.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121248729","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}

A well-known topology is the interleaved buck converter (IBC), which presents as main characteristic a low ripple output current source behavior. Due to HID lamp voltage source characteristics and their acoustic resonance issue, it is necessary to drive them with nearly constant current with a square-wave shape. Therefore, a buck-interleaved converter can be advantageous for supplying high power HID lamps. The goal of this paper is a proposal of an electronic ballast based on a two-cell buck-interleaved converter for high power HID lamps, with current control loop, voltage sensing and constant power. A DC model based on averaged state-space technique is derived for the ballast, as well as an AC model based on small-signal disturbances. The results are verified experimentally and through simulation in Matlab/Simulink and PSIM softwares.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128985963","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}

More effective aftertreatment technology is thus needed particularly for particulate matter (PM). Although the use of ceramic diesel particulate filters (DPF) is a leading technology in automobiles, it still presents a problem in terms of soot removal or regeneration for marine diesel engine operated with marine diesel oil (A-heavy fuel oil) including the sulfur. In the present study, to establish a nonthermal plasma DPF regeneration method for marine diesel engines, laboratory-scale and pilot-scale experiments are carried out. The pressure difference decreased only when the plasma is turned on and that regeneration is realized at 320°C. The amount of ozone required for regeneration is determined under various engine-operating conditions, and basic characteristics of regeneration are clarified. The required plasma energy is approximately 5% of the generated power of the marine engine.","PeriodicalId":268988,"journal":{"name":"2011 IEEE Industry Applications Society Annual Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125977226","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 paper describes the models used for the study, discusses the impacts of PV-DG, and presents the results of detailed simulations. The results show that PV-DG can cause both steady-state and transient overvoltages along the feeder, and may create additional tap operations of line voltage regulators.

The wavelet-based speed controller provides the command torque current for the drive system. A wavelet based de-noising technique is used inside the speed controller in order to minimize the torque ripple, which reduces the iron losses of the motor.
