摘要

本文旨在無需光源感測器的情況下達成雙軸追日系統的實現。本文的重點是使用太陽能板電壓差來判斷太陽的正確位置。本文使用Arduino單晶片模組搭配模糊控制驅動太陽能板方位達成追日的目的。本文設計時亦將外部擾動可能造成系統誤判的部分列入考量，實驗結果顯示，本系統採用的理論與設計可以精準的達成追日的目的。本實驗具有以下特色:
(1)不需光感測器的設計:
由於光感測器容易受到環境干擾影響,故設計上採用不需使用光感測器達到追日之作用
(2)嵌入式晶片設計:
本追日系統使用嵌入式晶片系統自動運算相關參數,不需要連接電腦進行相關參數運算
(3)簡易機構設計:由於機構設計簡單, 可以安裝在車上進行追日

This thesis proposes a dual axis solar tracking system without using any photodetector. The advantage of this study is using the voltage difference between areas ofa solar panel to determine the correct direction of the sun. In order to track thedirection of the sun, the author has designed a fuzzy controller by using themicroprocessor Arduino module to activate the stepping motors to adjust the directionof the solar panel. Environmental interference is also taken into account in order toavoid erroneous judgment in the system. The final experiment result shows that thetheory and design presented inthis thesis can accurately trace the position of thesunlight. Here are the characteristics of the dual axis tracker: Sensorless design: Since photo sensor could be interfered by ambient environment, our dual axis trackers is achieved without using sensor.
(1) With standalone controller: The dual axis tracker is with Arduino controller installed. The data can be automatically calculated in this controller
(2) With portable mechanical design: The dual axis tracker is with light weight which can be used at golf car.
