本論文應用區間二型(IT2)強健多項式模糊時延相依系統，設計直流/直流雙向轉換器之強健H∞控制器。本論文於推導之非理想狀態空間模型中狀態變數加入誤差積分項，使雙向轉換器輸出電壓之穩態誤差能趨近於零。本論文將雙向轉換器之升、降壓模式存在之二極體偏壓視為一固定之外在干擾訊號，並以H∞指標抑制干擾對系統輸出之影響，同時考量元件特性造成之時間延遲回授訊號，及系統參數的不確定性，推導定理一為雙向轉換器之IT2 H∞多項式模糊時延相依穩定定理。此外，以模型參數不確定性克服實際操作元件參數變動，導致降低控制性能問題，推導定理二為雙向轉換器之IT2強健多項式模糊時延相依穩定定理，將定理一及定理二之穩定條件式以平方和(SOS)形式表示。最後，以自行研製之最大額定功率2kW雙向轉換器及TI控制板，實現強健H∞多項式時延相依系統之控制，並透過輸入電壓變動、Duty干擾、負載變動、電感變動、及電容變動等測試，與未考慮時延之強健多項式做比較，突顯所設計之控制器性能為最優異的。

This thesis adopts Interval Type-2(IT2) Robust Polynomial fuzzy systems with time-delay dependent to design robust H∞ controller of DC-DC bidirectional converter. By adding integration of tracking error to non-ideal state-space equations, steady error of output of bidirectional converter approaches 0. To derive first theorem of IT2 H∞ Polynomial fuzzy time-delay dependent stability theorem of bidirectional converter, considering diode bias of both buck and boost mode to be a fixed disturbance signal, the influence of disturbance signal is attenuated by H∞ performance index, also considering time-delay feedback signal and uncertainty of system parameter caused by component characteristics. To derive second theorem of IT2 robust Polynomial fuzzy time-delay dependent stability theorem by using model parameter uncertainty, which can overcome the variation of component parameter which reduce control performance. First and second theorem are expressed in SOS(Sum of Square) form. The robust H∞ polynomial time-delay dependent system controller is achieved by bidirectional converter with 2kW rated power and TI microprocessor. To prove the performance of the designed controller is better than robust polynomial controller without considering time-delay by comparing with the input voltage variation, duty disturbance, load variation, inductance variation and capacitance variation experiment.
