H∞ control technique is adopted to control the states of the model in the presence of uncertainties and disturbance. Concept of servo mechanism is used to check velocity-tracking performance, while μ analysis is performed on the controlled model to check the robust stability and robust performance of the model.","PeriodicalId":416187,"journal":{"name":"2017 International Conference on Electrical Engineering (ICEE)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132054529","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}

All 3G and 4G wireless technologies use OFDM and FFT is an integral block of transceiver loop. In this paper three FFT architectures are designed that fall within the Cooley-Tukey class of algorithms. These FFT designs are targeted for OFDM applications especially in future generations of Software Defined Radio (SDR) systems. The FFT is performed on 64-point complex valued input samples with 16-bit precision. Each core is optimized for a combination of area, power, and speed. The design is targeted for a partially reconfigurable FPGA platform such as Xilinx Virtex-4 or above. The FFT cores have been simulated in Model Sim and synthesized using Xilinx ISE software. The cores can be readily downloaded on to target FPGA board to check for run time configurability. The performance evaluation of these cores show that they run at clock frequency of about 80MHz.","PeriodicalId":416187,"journal":{"name":"2017 International Conference on Electrical Engineering (ICEE)","volume":"20 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113978820","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}

Although there has been an extensive use of CCT for a long time but a lot of problems and issues such as inrush current, saturation, current transformer ratios, etc. faced by CCT make its use quite limited. Issues arising in CCTs have pulled the attraction of researchers and protection engineers towards a new instrument technology based on Opto-Electromagnetics. An Optical Current Transformer (OCT) model based on the simulation has been proposed here which follows the Faraday's law of Electromagnetics. The use of OCT will resolve almost all issues that were being faced by CCTs. So this new designed model of OCT can replace easily the CCTs for both the protection and metering purposes. This simulation model of OCT using operational amplifiers is being proposed here just to motivate the protection and design engineers especially in Pakistan to adopt the new technology of OCT for the measurement of current in place of CCT. In addition to resolving all issues related to CCT, OCT will also make the power quality better. Three types of outputs can be obtained from an OCT which are: low energy analog output (LEA), high energy analog output (HEA) and digital output. Due to sampling rate limitations involved, a digital output is hard to use to avail the wider bandwidth option. To use all the benefits of an OCT, a low energy output signal will be used here for the simulation requirement here. After the required OCT model development, simulation results will be included to prove that CCT can be replaced by the OCT.","PeriodicalId":416187,"journal":{"name":"2017 International Conference on Electrical Engineering (ICEE)","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134520803","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 main objective is to establish a non-linear model of cricket bowling arm in SimMechanics and implementation of optimal control based for different bowling actions. This modeling framework mimics the bowling actions of an any bowler with specific parameters and analysis its strength and weakness. We obtained a state space model of bowling action from linearization through SimMechanics and then subjected it to linear quadratic regulator for control feedback. The results of simulation show physical dynamics of actual cricket bowling action and it also realizes stability control of velocity and displacement curve. These results demonstrate the applicability of this modeling and control framework for further analysis and study of individual bowling actions.","PeriodicalId":416187,"journal":{"name":"2017 International Conference on Electrical Engineering (ICEE)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133577297","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 state space method is used to develop the proposed strategy. The Eigen values of the proposed controller are compared with the discrete-time linear quadratic regulator (DLQR).

The proposed approach results in 81.55% less percentage error and 42.85% less average error compared to previously reported best two region based approximation approaches with comparable area cost and latency. The proposed method uses most significant four bits of fractional part of shift and add-based method with different weights to approximate fractional part of log2.
