    Abstract: 本論文旨在應用T-S模糊控制法於永磁同步發電機之驅動器研製。T-S模糊控制法常應用於非線性系統之控制,其中使用解模糊化過程、平行分佈補償(PDC)設計、Lyapunov穩定度分析,並採用線性矩陣不等式(LMI)得到控制增益值。永磁同步發電機驅動系統等效電路藉由兩相調變(TPM)推導以減少切換損失。本論文首先敘述系統之架構以及發電機各區間之狀態方程式推導,接著推導T-S模糊控制法及LMI型式。本系統將永磁同步發電機之三相交流電轉換為直流電供應至負載端,經由類比/數位轉換回授直流鏈端電壓以及三相電流至微控制器,代入控制器以求得開關之責任週期比。最後以實驗結果驗證控制器性能。
    The main purpose of this thesis is to design and implement the permanent-magnet synchronous generator (PMSG) drive using T-S fuzzy control. The T-S fuzzy control is generally applied to the control of nonlinear systems. The defuzzification, parallel distributed compensation (PDC) and Lyapunov stability analysis are implemented in the design of T-S fuzzy control. The Linear Matrix Inequality (LMI) is adopted to obtain the controller gais. In order to reduce switching losses, the equivalent circuit of the PMSG drive system is derived from two phase modulation (TPM). First, the system configuration and state equation of each region of the PMSG are introduced in this thesis. Next, the T-S fuzzy control and the LMI are derived. The three-phase AC power of PMSG is converted to DC power for loads. The DC link voltage and three-phase current are sensed to the microcontroller through analog-to-digital convertion (ADC). The duty ratios of the power switches are calculated via the controller. Finally, the controller performance is verified by experimental results.
