摘要

本研究主要在探討使用MATLAB軟體，開發一套太陽能最大功率追蹤系統之模擬程式，此套軟體主要架構分為3大部分，分別為太陽能電池、升降壓電源轉換器以及最大功率追蹤。首先我們先將太陽能電池部分與升降壓轉換器的部分做整合，驗證系統可行性之後，再將最大功率法則加入太陽能模擬系統做最大功率追蹤模擬。本文使用擾動觀察法、增量電導法與模糊控制進行分析與模擬，最後使用MATLAB的GUI圖形化介面功能將本套系統藉由圖形方式呈現，方便使用者操作。此系統可用於工程與教育應用，以加速熟悉與學習太陽能最大功率追蹤系統。

This thesis presents the development of an integrated computer simulation program for solar power maximum power point tracking system. The simulation framework mainly con-sists of three major parts, a PV simulation model, dynamic model of the SEPIC/Zeta/Synchronous four-switch type buck-boost converters, and fuzzy logic based maximum power point tracking algorithms. The maximum power point is achieved by con-tinuously adjust the duty ratio command for the power converter. First, we integrate the PV model and dynamic model of the converter in pure computer program. The simulation re-sults demonstrate the solar power system is feasible by using pure MATLAB computer pro-gram. Perturb and observe method, incremental conductance method, and fuzzy logic based MPPT controllers are then integrated into the simulation program. Final MATLAB based graphic user interface is designed to facilitate understanding of the MPPT system. The sys-tem can be used for both engineering and education purposes.
