This paper uses a set of orthogonal hybrid functions (HF) for analysing and identifying control systems with jump discontinuities. But with traditional hybrid function theory, the results obtained are not quite satisfactory. To obtain a more accurate as well as reliable result, a modified version of the hybrid function set is attempted to design a new theory. With this new theory, jump functions are approximated in a better manner and subsequently these principles are applied for the analysis and synthesis of control systems described by their state models. Relevant examples are treated and results are found to be far more acceptable than those obtained using traditional hybrid functions.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"23 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":"122231873","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 signal is also subjected to Frequency Domain techniques to estimate the power generated by muscle under different loading conditions. The Fractal Dimension, as obtained here, is found to vary under different loading conditions.

The possible limitations of the controller have been conquered by implementing innovative ideas and techniques for calculation of switching time and selection of switching states. The execution time of the program is also reduced by developing a special algorithm for division, multiplication and `sin' function involved in the calculations. A prototype has been developed to test the effectiveness of the algorithm and satisfactory responses are found.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"440 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":"122931425","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 Multifractal Detrended Fluctuation Analysis (MF-DFA) shows that the EEG signals have different degree of multifractality and we suspected this variety is due to various stages of sleep. In an attempt to identify the origin of multifractality we extend our study and produce surrogate data set. Applying MF-DFA method on the surrogate data set we find that this multifractality is caused by both the long-range correlation appearing due to large and small fluctuations and broad probability distribution. However the first one has more influence on the multifractality of the EEG signals during sleep.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"246 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":"116143469","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 grid is one such real world network in which a technique of analyzing the location of a distributed generation in a distribution system of a grid has been applied based on complex network theory. The metric of electrical centrality is the approach used in differentiating the physical and electrical topological structure of the chosen network. Z-bus matrix represents the more electrically central nodes and it has been found out directly by the formulation of the Z-bus algorithm as it is more practical for larger systems. The results were obtained for 33-bus distribution system from which the locations of the DGs to be placed were found out. This complex network theory based method improves the voltage profile of the system significantly. By placement of one or more DGs in these electrically central nodes, the losses have also been optimized.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"1 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":"131892111","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}

In order to overcome sluggish response of induction motor and to have decoupled flux and torque characteristics, field oriented control (FOC) is implemented. These drives consists of voltage source inverters with various modulation schemes like SPWM, THISPWM, SVM etc. in order to minimize the harmonics present in the output voltage or current. Presence of harmonics makes the response non-sinusoidal and generate heating, torque pulsation etc within the machine. But for field oriented control induction motor drives, selection of efficient modulation scheme is important as machine current is controlled and in this current loop presence of ripples may create multiple zero crossing problems in the SPWM. In this paper, different modulation schemes are investigated and their performances are compared for a variable speed three phase FOC Induction motor. This system is modeled in MATLAB and SIMULINK where all the above stated modulation schemes are implemented. It is observed that the FOC based IM drive gives better result when subjected to Space Vector Modulation Scheme.","PeriodicalId":443343,"journal":{"name":"2016 2nd International Conference on Control, Instrumentation, Energy & Communication (CIEC)","volume":"63 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":"132699548","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}
