Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. The unique feature of the proposed system is that instead of taking the earth as its reference, it takes the sun as a guiding source. Its active sensors constantly monitor the sunlight and rotate the panel towards the direction where the intensity of sunlight is maximum. The light dependent resistor's do the job of sensing the change in the position of the sun which is dealt by the respective change in the solar panel's position by switching on and off the geared motor. The control circuit does the job of fetching the input from the sensor and gives command to the motor to run in order to tackle the change in the position of the sun. With the implementation of the proposed system the additional energy generated is around 25% to 30% with very less consumption by the system itself. In this paper, an improvement in the hardware design of the existing solar energy collector system has been implemented in order to provide higher efficiency at lower cost.","PeriodicalId":156837,"journal":{"name":"2011 1st International Conference on Electrical Energy Systems","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123078281","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}

Some control Technique is applied to yield basic assist logic, return compensation logic, damping compensation logic, and inertia compensation logic in an assist steering system according to steering wheel angle and vehicle speed. The PMSM drive in an EPS system can be considered as a torque amplifying and tracking system. When the driver of the vehicle moves the steering wheel, a torque sensor in the steering mechanism sends a torque signal to the EPS controller. The DSP inside the EPS controller receives the torque input and sends it to a torque command algorithm. The torque command algorithm processes the torque input, along with other inputs, such as vehicle speed, motor speed, and generates a torque command to the PMSM drive subsystem. The PMSM drive controls the PMSM motor to generate an output torque that tracks the desired torque demand.

Considering a dynamic model of the PM machine allows powerful control-theoretic techniques such as, linearization to be applied to the system. Existing feedback linearization techniques suffer from the limitations of singularity. In this paper, input and state transformations are derived for a 4 dimensional PM machine model for linearization of PMSM model. The proposed technique does not introduce singularities in the system. A Simulink model is developed for the IPM motor. Tuning transformations have been derived for the given machine by comparing the output of linearized machine with that of the normal form. The simulation including tuning transformation is also done and better results are obtained for linearization.","PeriodicalId":156837,"journal":{"name":"2011 1st International Conference on Electrical Energy Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121527384","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}

ILWT based wavelet uses time domain for its integer calculation and could lessen calculation complexity due to its structure, compared with modified wavelet transform (MWT) and wavelet transform (WT) which depends on floating point coefficients. The whole method is tested over sample disturbances like voltage sag, voltage swell and harmonics. As shown by the simulation experiment results, the proposed approach displays a good decomposition of various power quality waveforms. The hybrid active filter is modeled using P-Q theory and simulation studies are performed using MATLB software. The simulation results, the proposed approach displays a good reduction in harmonics in comparison with passive filter, active filter and hybrid active filter.","PeriodicalId":156837,"journal":{"name":"2011 1st International Conference on Electrical Energy Systems","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121712530","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}
