摘要


本論文主旨在設計一個以擾動觀察法跟模糊控制理論所研製之太陽能最大功率追蹤系統。當負載改變時,系統經由擾動觀察法跟模糊控制理論得到最大的功率輸出點。 本論文系統是以太陽能板、升降壓轉換器、電壓回授電路、電流回授電路、全橋式換流器及變壓器所組成,以數位信號處理器DSP TMS320 F2812核心晶片來設計程式,回授電路之訊號經DSP進行高速運算處理控制太陽能最大功率輸出。 本論文的擾動觀察法獲得最大功率點,再另以模糊控制理論優化。模糊控制理論是以擾動觀察法為基礎進行設計改良,藉著改變太陽能板輸出的電壓及電流改變量進行模糊運算,獲得降壓轉換器的責任週期D改變量的大小,藉此快速的找到太陽能的最大功率輸出點。

The main purpose of this thesis is to develop the solar maximum power point tracking system by design a perturbation observation method and fuzzy control theory. When the load changed, the system attains the maximum power output point through these two theories. This thesis system consists of solar, Buck-boost Regulators, Voltage feedback current feedback, circuit full-bridge converter and transformer. Use DSP TMS320 F2812 core chip to design the program. The feedback signal circuit gets the maximum power point by high speed operation controllable with DSP. This thesis got the maximum power by perturbation observation method, and then to optimize via using the fuzzy control theory. To improve the fuzzy control logic is base on perturbation observation method. And to found the maximum power point by change the solar voltage and current with fuzzy operation to got buck converter duty cycle D changeable.
