Abstract:
ان الحاجة لزيادة توليد الطاقة الكهربائية جعل استخدام الخلايا الشمسية تلعب دورا هاما في الحياة اليومية، وعليه من المهم استخدام نظام يسمح بتتبع الخلايا الشمسية لضوء الشمس لزيادة او الحصول على القيمة المثلى للطاقة الكهربائية من الخلايا الشمسية. تم في هذا ا | The need to increase the energy generation makes the use of solar cells plays an important role in the daily life. For this reason, it is important to use solar tracking system to increase or getting almost optimum value from solar cells. In this thesis, solar cells model was implemented using MATLAB to show the characteristics of any solar cell depending on data sheet. Intelligent controllers was designed and used to make solar cells facing the sun all days. The proposed controller was trained by two ways; the first was trained by supervised feed forward neural network and the second by Particle Swarm Optimization (PSO) and then comparing the results obtained. The controller was trained using MATLAB and the converting it to simulink model in order to test it, and converts, it to a Very high speed integrated circuit Hardware Description Language (VHDL) language using MATLAB tool box in order to download it on Spartan 3A Field Programmable Gate Arrays (FPGAs) card. This makes the implementation of the intelligent controller more efficient and easy to use because of its reprogram - ability and the high speed performance. The controller was designed to a fully controlled DC motor driver which is used to rotate two DC motors in X - axis and Y - axis directions respectively.The experimental results show that tracking sun increases the efficiency of the system to produce energy from solar cell about 44.3778 % more energy than the solar cell without tracking system.
