Four voids are located between every two grooves where the piezoresistors are placed. These piezoresistors are electrically connected with aluminium wires to form a Wheatstone bridge. By introducing grooves around the diaphragm, more stress is concentrated in the void regions, resulting in high sensitivity. In addition, improvement in the performance of the sensor has been attained by modifying its geometrical dimensions. On the basis of simulation experiments, the proposed pressure sensor has achieved a high sensitivity in the range of 45.41 mV/V/Kg.cm-2 to 48.25 mV/V/kg.cm-2 by taking different lengths of piezoresistors varying from 300 μm to 120 μm. The pressure sensor has a very low nonlinearity compared to other pressure sensors within this range. The design and simulation of the proposed piezoresistive pressure sensor is carried by using COMSOL Multiphysics 5.2a.","PeriodicalId":445688,"journal":{"name":"2018 International Conference on Recent Trends in Electrical, Control and Communication (RTECC)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130061461","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 suitable control system should be in place to ensure the optimum function of the Three-Phase Separator. The current PID tuning technique does not provide an optimum system response of the separator. Overshoot response, offset, steady-state error and system instability are some of the problems faced. Besides, the current method used is purely based on trial and error which is time consuming. There is room for improvement of the current PID tuning technique. An artificial intelligence (AI) PID tuning technique called Particle Swarm Optimization (PSO) is introduced to improve the system response of the Three-Phase Separator. The PSO algorithm mimics the behaviour of bird flocking and fish schooling striving for its global best position. In our case, the global best position is replaced with the optimized PID tuning parameters for the separator. The PSO algorithm has been used in several other applications such as the Brushless DC motor and in the Control Ball & Beam system. It has proven to be an effective tuning technique. Tuning of the Three-Phase Separator via PSO could prove to be an effective solution for Oil & Gas industries.","PeriodicalId":445688,"journal":{"name":"2018 International Conference on Recent Trends in Electrical, Control and Communication (RTECC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125247034","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 model approximation is executed by minimizing the Integral Square Error (ISEI) between the unit impulse responses of the original system and the approximate model along with the retention of their Impulse Response Energies (IRE), by using a hybrid evolutionary (i.e. PSO-DV) algorithm. The Reduced Order Model (ROM) developed by this method assures the properties of preserving the stability, passivity, and the dynamic behaviour of the original hydro power system. The suitability of ROM is shown by designing a PID controller and the same is used to control load frequency response of the original hydro power system to the desired value. The gains of PID controller are tuned by minimizing the Integral Square error (ISEc) between the desired and actual response of the ROM, by using the same PSO-DV algorithm. The efficacy of the approximate model and the controller designed is shown by comparing some of the performance error indices and the time responses.","PeriodicalId":445688,"journal":{"name":"2018 International Conference on Recent Trends in Electrical, Control and Communication (RTECC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114601102","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}

Due to its significance, a considerable research works are obtainable in the literature. This work implements a semi-automated computer based tool to extract the tumor region from the benchmark BRATS 2015 brain MRI database. A process by incorporating the thresholding and level-set (DRLS) segmentation is implemented to extract the tumor section from the MRI. Initially, Kapur’s entropy assisted thresholding is implemented to improve the tumor section; later the segmentation practice is executed to extract the tumor. After extracting the infected segment, a comparative investigation is accomplished with respect to the ground truth (GT) image in order to evaluate the performance of the proposed semi-automated tool. The experimental results of this work confirm that, proposed approach offers better average result for the Jaccard, Dice, sensitivity, specificity and accuracy. In future, this procedure can be considered to examine the real-time brain MRI obtained from the clinics.","PeriodicalId":445688,"journal":{"name":"2018 International Conference on Recent Trends in Electrical, Control and Communication (RTECC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115654474","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}

DC-DC boost converters are universally used in Non-Conventional energy applications. But the high switching frequency increases the power loss due to switching and hence the power converter efficiency decreases. To increase the converter efficiency soft switched boost converters (SSB) are used. But the voltage from input (renewable energy sources) is always not constant; it remains in its specific manner. This varying voltage has to be maintained constant which helps to charge the DC battery. To sustain the output voltage at a steady value, traditionally a PID controller is used for SSB converter. The design of PID controller was carried out using Zeigler Nichols tuning method. Simulation of SSB converters and SSB with controller was developed by MATLAB/SIMULINK. In this paper a fractional order PID controller is proposed for the SSB converter. Fractional order PID controller has additional tuning parameters called fractional integral order and fractional derivative order. The simulation of the SSB converter with fractional order PID controller was also carried out in MATLAB/SIMULINK. For fractional order PID controller implementation, the CRONE toolbox is used. The performances of the SSB with fractional order PID controller were tested under varying input conditions and varying load conditions and the results were reported.","PeriodicalId":445688,"journal":{"name":"2018 International Conference on Recent Trends in Electrical, Control and Communication (RTECC)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114422684","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}
