The performances of several classical integer-order (IO) controllers such as I, PI and PID controllers is evaluated and compared with IλDμ controller to assess the best controller. Investigation reveals that IλDμ controller provides better performance than the IO controllers in terms of settling time, reduced oscillations and peak overshoots. This paper employs bacterial foraging algorithm for optimization of gains and other parameters such as order of integrator (λ) and differentiator (μ) in case of IλDμ controller. Further, sensitivity analysis is carried out for the first time in the system considered to investigate the robustness of the optimum gains, λ and μ of IλDμ controllers obtained at nominal condition.","PeriodicalId":336723,"journal":{"name":"2012 1st International Conference on Power and Energy in NERIST (ICPEN)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122386975","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}

This paper presents efficient compensated Cascaded Integrator Comb (CIC) decimation filter to improve the passband of interest using redundant signed digit arithmetic with its power analysis. Signed digit (SD) number systems provide the possibility of constant-time addition, where inter digit carry propagation is eliminated. A hybrid adder can add an unsigned number to a signed-digit number and hence their efficient performance greatly determines the quality of the final output of the concerned circuit. With the development of high speed processors, a tradeoff is always required between area and execution time to yield the most suitable implementation with low power consumption. The proposed work analyzed the power performance of compensated CIC decimation filter with decimation factor 64 on the bases of its On-chip leakage power and dynamic power with the variation of word length in narrow band and wide band filtering. This paper also utilized signed digit (SD) algorithm to incorporate the key features of the conventional number system with a signed digit (SD) to improve the addition time with high power constraints in an optimized fashion. CIC decimation filter with SD algorithm shows a 63.68% and 39.65% gate delay × dynamic power improvement relative to RCA and HSD fast adder algorithm respectively.","PeriodicalId":336723,"journal":{"name":"2012 1st International Conference on Power and Energy in NERIST (ICPEN)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122048662","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}

Most of the methods for stator winding inter-turn fault diagnosis are based on Motor Current Signature Analysis (MCSA) combined with signal-and-data processing tools. Fault diagnosis using MCSA becomes more challenging when stator current signatures due to winding short circuit fault and supply voltage unbalance appear identical. The present paper proposes a method through analysis of Park's Vector Modulus (PVM) to discriminate stator winding inter-turn fault cases, from supply voltage unbalance conditions where both cases exhibit apparently similar kind of current signatures. A series of experiments have been performed on a motor with different degrees of stator winding inter-turn faults. The same motor under healthy condition was also tested while operating under unbalanced supply voltages that caused similar current unbalances as in the case of inter-turn short circuit faults. This work aims at identification of the motor voltage unbalance conditions separately from inter-turn fault cases through detection of high frequency signals present in different PVM profiles. Signal processing tools such as Fast Fourier Transform (FFT), Discrete Wavelet Transform (DWT) and Power Spectral Density (PSD) calculation have been employed to discriminate inter-turn short circuit faults from supply voltage unbalance conditions of the motor at different load levels. Entire analysis presented in this paper is based on experimentally obtained motor current signatures.","PeriodicalId":336723,"journal":{"name":"2012 1st International Conference on Power and Energy in NERIST (ICPEN)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123984246","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}
