最大功率追蹤器與雙向轉換器之T-S模糊建模與控制

本論文中，我們以近幾年被廣泛使用於非線性系統的T-S模糊理論，針對太陽能直流微電網之供電系統進行T-S模糊化的建模與控制，其中包括太陽能光電板、最大功率追蹤器、雙向轉換器等模組。對於直流微電網系統而言，任何硬體電路或是控制方法的改變，其造成之影響往往複雜且難以分析。藉由系統建模，將可應用電腦模擬來輔助分析並減少資源的損耗。本論文先分析太陽能供電系統中各模組之基本電路架構、開關切換模式及責任比率控制法則，接著建立電腦模組，並比較T-S模糊控制法與傳統控制法的優劣。

T-S fuzzy theory has been widely used in nonlinear systems in recent years. In this thesis, we use T-S fuzzy theory to model and control the photovoltaic (PV) microgrid which includes a PV array, a maximum power point tracker (MPPT) and a bidirectional converter. Computer simulation results are verified by experimental results. Changing the control method or circuit configuration of the dc microgrid will affect the overall system and become hard to analyze. After system modeling, computer simulation can show the effects on dc microgrid and reduce the waste of resource. In this thesis, we first analyze circuit configuration, switches operation and duty ratio control law in each modules. Then the models are established for computer simulation, and we compare the advantages and disadvantages between T-S fuzzy control and the traditional control.
