This machine can be used in grid isolated and remote areas as a portable source of power supply. The reactive power requirement for this type of generator is provided through a single capacitor of suitable value and a single phase inverter with a photovoltaic (PV) module which acts as a dc bus to the inverter. The inverter along with the PV module acts as a variable source of excitation during the variable load and wind speeds which aid in providing stable load voltage with fixed frequency. Performance of such a generation scheme is analyzed using suitable simulations and experiments. The scheme shows encouraging results and thus also validates the proposed strategy.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133513704","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}

As further steps of performance improvement of the missile attitude control system, the LTR and LQI schemes are applied to increase the stability margins and guarantee set-point tracking performance respectively, while also preserving the optimality of the LQG.

Farming is still dependent on techniques which were evolved hundreds of years ago and doesn't take care of conservation of resources. The newer scenario of decreasing water tables, drying up of rivers and tanks, unpredictable environment present an urgent need of proper utilization of water. We have the technology to bridge the gap between water usage and water wastage. Technology used in some developed countries is too expensive and complicated for a common farmer to understand. Our project is to give cheap, reliable, cost efficient and easy to use technology which would help in conservation of resources such as water and also in automatizing farms. We proposed use of temperature and moisture sensor at suitable locations for monitoring of crops. The sensing system is based on a feedback control mechanism with a centralized control unit which regulates the flow of water on to the field in the real time based on the instantaneous temperature and moisture values. The sensor data would be collected in a central processing unit which would take further action. Thus by providing right amount of water we would increase the efficiency of the farm. The farmer can also look at the sensory data and decide course of action himself. We have made the interface of our project keeping in view the educational and financial background of average Indian farmer. In this paper we are proposed a low cost and efficient wireless sensor network technique to acquire the soil moisture and temperature from various locations of farm and as per the need of crop controller take the decision to make irrigation ON or OFF.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126245783","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 calls for accurate estimation of harmonics in power system so that more effective compensation measures are designed. However, accurate computation of all the harmonics is a challenging problem in power system. Even though many algorithms have been proposed for harmonic estimation to improve the power quality performance, but till date it remains a challenge. In this paper two nonlinear adaptive filtering algorithms called Volterra Least Mean Square (VLMS) and Volterra Recursive Least Square (VRLS) are applied for the first time for estimating harmonic parameters. These approaches have been considered to estimate the amplitudes, phases and frequency in case of time varying power signals containing harmonics in the presence of White Gaussian Noise in MATLAB simulating environment. Also comparison results with VLMS and VRLS algorithms are presented to show the effectiveness of the proposed VRLS algorithm.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123064141","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}

From the beginning of 21st century, drastic improvement in the harmonic profile and increased power rating of MLI made them highly popular for high power application. MLI's are widely utilized in industrial field employing motor drives, static VAR compensators and renewable energy systems, etc. Basically output voltage of a MLI has multiple levels as compare to conventional inverters. This increment in output voltage levels greatly affect the harmonic distortion due to which the output voltage is negligibly distorted and high quality of output waveform is obtained. Because of this features the MLI are highly preferred for high voltage and high power application. Up till now many topologies for MLI have been reported. Moreover, three major MLI structures are there, Cascaded H-bridge having isolated dc source, diode clamped and flying capacitor. Though there are various types of MLI are available, CHB MLI is one of the most productive topology among multilevel family. The CHB MLI is further divided in two configuration viz., symmetrical and asymmetrical CHB MLI. It depends on cascade connection of number of H-bridge inverter cells energies by the supplies which are in geometric progression (GP) with different ratios like 2,3 etc. This paper presents cascaded MLI approach for high voltage and high power output application, in which symmetrical and asymmetrical arrangements of seven level and nine level CHB MLI are investigated for structural and operational characteristics. Simulations are carried out in Matlab Simulink to analyzed the performance of Asymmetrical CHB MLI using SPWM technique. Simulation result for this proposed scheme are shown in this paper.","PeriodicalId":353124,"journal":{"name":"2014 First International Conference on Automation, Control, Energy and Systems (ACES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129582324","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}
