Design of high precision and reliability tracking sun system

For the high precision and high reliability of the track the sun and improving the utilization of solar energy,the paper designs a control system based on the C8051Fa020;C8051Fa020 as controller of the system,MCU through position of the sun formula,calculated the solar elevation angle of the sun and elevation angle,pitch and height of the program control the motor rotation,to achieve accurate tracking of the position of the sun;while taking advantage of solar power installed in the encoder structure as the feedback to achieve closed-loop tracking system control,it corrects the error of tracking system,to improve the accuracy of tracking systems;through the experimental field of solar architecture,tracking system can accurately track the position of the sun,system performance and stability,low cost and very practical.
