Abstract:	傳統交換式電源供應器(switching mode power supply)係採用脈波寬度調變(PWM)方式進行輸出穩壓調節，例如降壓型的輸出電壓若偏低則增加脈波寬，當輸出電壓若偏高則減少脈波寬，以控制隱定的電壓輸出。本論文提出自我調整模糊控制系統，整個控制器所需之參數將可自我線上學習調整，並且可確保受控系統之穩定性。接著，在硬體實現方面，配合現代硬體發展的趨勢，朝向輕薄短小的產品設計概念，本論文使用利用Altera公司所推出之NIOS II系統開發板來實現所設計開發之智慧型穩壓控制法則，從實驗結果中可 The DC-DC converters which convert one level of electrical voltage to the desired level are widely used in many electrical peripherals. This paper proposes a self-tuning nonlinear function control (STNFC) system for a DC-DC converter. Since the STNFC uses
