The industrial equipments which are governed by PID controllers have simple control structure and efficiency but still they suffer from large power consumption and slow mathematical computation. Many researchers have tried and are trying to design a low power, delay less PID. This paper reviews three MAC architectures with array, booth and wallace tree multipliers which in turn incorporated in PID architecture. The simulations are done in Modelsim and power results are synthesized using Xilinx ISE. The results suggest that Wallace tree based MAC unit consumes less power and area.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132538562","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 addition it cannot operate the module at its maximum output power in rapidly changing of weather conditions. So, there is a need of MPPT system to sample the output of the cells and apply the proper resistance(load)to obtain maximum power for any given environmental conditions. A new method to track the global MPP is presented, which is based on Ant Colony Optimization (ACO) combined with Particle Swarm Optimization (PSO)that controlling a DC-DC converter connected at the output of PV array, such that it maintains a constant input-power load. This model indicates the DC-DC converter is an interleaved boost converter topology which will increase the efficiency and reduce the ripple factor which is easily control and greater stability can be achieved. By using this model we get very low conduction and switching losses then switching frequency is improved and size of the system also reduced. The proposed method has the advantage that it can be applied in either stand alone or grid-connected PV systems comprising PV arrays with unknown electrical characteristics and does not require knowledge about the PV modules configuration.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132180007","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 proceed, the signal from the force sensors (placed underneath each foot) were first divided according to the fundamental period by auto-correlation. This ensures that each period contains a full stance phase and two fragmented swing phases. After this step, Short Time Fourier transform has been performed on each period of the signal to detect the initial search point (highest DC value) on the stance phase. Then by judging the width and slope of the straight line from changing search points on the signal to a changing destination point (starting from the minimum or maximum time value) of the graph the onset and offset of the stance and swing phase has been detected. The changing search point has small distance from the previous one, if the slope of the signal is small, but the distance increases with the increasing change of slope of the signal. The destination point changes with the change of slope of the straight line. This algorithm has been applied to the signals in the database of Parkinsons disease, which shows a success rate of more than 90%.","PeriodicalId":202856,"journal":{"name":"2015 2nd International Conference on Electronics and Communication Systems (ICECS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130588402","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}
