    Abstract: 本論文旨在利用T-S模糊控制法開發雙向充放電器與永磁同步發電機驅動器系統。利用解模糊化過程、平行分佈補償(PDC)設計、Lyapunov穩定度分析以及LMI(Linear Matrix Inequality)數值分析求解來實踐T-S模糊控制法設計。發電機的三相電流經由整流器轉成穩定的380V直流電接入直流鏈,與雙向充放電器的高壓側連接,再將雙向充放電器的低壓側接入鋰鐵電池。當發電機供至直流端負載能量有多餘時,雙向充放電器操作在降壓模式對鋰鐵電池以定電流方式充電;若發電機供至直流端負載能量不足時,雙向充放電器則操作在升壓模式,即鋰鐵電池放電。實測中以發電機在不同的轉速及電流命命下,改變輸出功率;以雙向充放電器因負載變動以及電流命令改變下,均能達到所設定的目標值,來達成系統性能之驗證。
    The main purpose of this thesis is to develop the bidirectional charger/discharger and permanent-magnet synchronous generator (PMSG) drive system based on T-S fuzzy control. The design of T-S fuzzy control is accomplished via defuzzification, parallel distributed compensation (PDC), Lyapunov stability analysis and Linear Matrix Inequality (LMI) numerical analysis. The three-phase current of the PMSG is converted to a stable 380V DC voltage and connected to the DC bus. The DC bus is connected to the high voltage side of the bidirectional charger/discharger. The Lithium-iron battery is connected to the low voltage side of the bidirectional charger/discharger. When the output power of the PMSG is larger than the DC loads, the bidirectional charger/discharger is operated at buck mode to charge the Lithium-iron battery under constant current mode. When the output power of the PMSG is smaller than the DC loads, the bidirectional charger/discharger is operated at boost mode to transfer energy to the DC bus. In experimental results, the output power of the PMSG is changed under variable speed and current command. The desired value are achieved by the bidirectional charger/discharger under load variation and current command variation to validate the performance of the system.
