The plant model considered here is a dynamic model of power system that includes the turbine, governor, load and machine dynamics subjected to control the load frequency in accordance with power input to the governor. In the present contribution, a proposal is being presented to automate the loop shaping phase in QFT design method to synthesize a robust load frequency controller that can undertake the exact amount of plant uncertainty and can ensure a proper trade off between robust stability specifications and plant input disturbances over the entire range of frequencies. In this article the PSO technique has been employed to tune the controller automatically that can greatly reduce the computational effort compared to manual graphical techniques. It has also been demonstrated that this methodology not only automates loop-shaping but also improves design quality and, most usefully, improves the quality with a reduced order controller.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"10 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":"126397370","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}

Signature verification is a socially accepted biometric method and is widely used for banking transactions. In this paper, we propose Cross-validation for Graph Matching based Offline Signature Verification (CGMOSV) algorithm. Database signatures are preprocessed in which signature extraction method is used to obtain high resolution for smaller normalization box. The dissimilarity measure between two signatures in the database is determined by (i) constructing a bipartite graph G, (ii) obtaining complete matching in G and (iii) finding minimum Euclidean distance by Hungarian method. We use Cross-validation principle to select reference signatures from which an optimum decision threshold value is determined. The given test signature is pre-processed and a test feature is extracted from it, which is then compared with the threshold value to authenticate the test signature. It is observed that our algorithm gives better Equal Error Rate (EER) for skilled forgeries and random forgeries compared to the existing algorithm.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"17 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":"134386984","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 actuation test system consists of an electrically driven hydraulic power pack feeding a linear actuator with a proportional valve controlling the flow to and from the actuator, while the power pack includes a reservoir, fixed-discharge axial piston pump, a pressure relief valve and a non-return valve. A non-linear state-space model for the system has been obtained with the command electrical signal to the proportional valve as the input and the actuator displacement as the output. Experimental characterization of actuator friction, the relief valve, the non-return valve and the transmission line along with a neural-network model for the proportional valve has been carried out and integrated to the model of the actuation dynamics. The model has then been used for performance prediction to assess the importance of each subsystem model through a comparison against experimental results. It has been found that the contributions of the valve modeling and actuator friction are significant. A need to characterize the end-cushioning effect has been identified.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"78 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":"132053085","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}

Theoretical principles of this method are presented along with simulation results. Advantages of VFDPC-SVM over other DPC techniques presented. The main advantages of DPC-SVM are its simple algorithm, good dynamic response and constant switching frequency operation. This paper compares VFDPC with lookup table and VFDPC with SVM approaches applied to PWM voltage source converters. DPC strategies use lookup table SVM, predictive vector selection or combination of more than one approach for generation of PWM pattern. Power calculations can be done using phase variables or instantaneous power theory. Analysis of VFDPC SVM pulse width modulated converter based STATCOM have been done in MATLAB/Simulink environment. Simulation results are presented. PWM pulses are generated and fed to Converter so as to maintain the power factor of the source at unity. Total harmonic distortion is calculated both in inverter output voltage and source current.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"5 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":"130852508","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}

Repetitive controllers are those control elements that strategically reduce or nullify the effect of these repeating signals. In motor gear transmission system, the tooth-to-tooth error manifests as periodic disturbance. Repetitive control has by now proved as an effective control scheme for improving periodic disturbance attenuation performance. This paper aims to formulate the repetitive controller design for the Motor-Gear system as an optimization problem with an LMI (Linear Matrix Inequality) constraint on the free parameter of the bandwidth of the filter and demonstrate the effect of such a controller through MATLAB simulation. The filter is used to cater to the stability requirements of the system with the repetitive controller incorporated with it. The form of the repetitive controller is based on a single parameter determined by the fundamental period of the disturbance. It is demonstrated through the results that the repetitive controller indeed reduces the periodic disturbances. Also as the bandwidth is increased, stability is found to be at stake whereas the disturbance rejection is affected if the bandwidth is reduced.","PeriodicalId":196254,"journal":{"name":"2008 Annual IEEE India Conference","volume":"4 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":"127771338","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}
