論文提要內容：
由於台灣地區夏季炎熱且潮濕，冷氣機的使用日漸普遍，因而造成夏季之用電量大幅成長，對電力系統造成極大的負荷。因此如何有效提升冷氣機的運轉效率以降低其耗電量為目前電機控制極為重要的課題。而由於變速驅動之冷氣機具有高冷卻力，良好的溫度控制特性等優點，已成為提昇冷氣機運轉效率之關鍵性的裝置。因此本研究的主要目的即是以模擬分析的方法探討冷氣機的運轉特性，並研製一利用轉子磁場導向感應馬達且適合於分離式冷氣機使用的最佳效率控制系統，最後並以實驗驗證控制系統的性能。

Abstract:
Because Summer in Taiwan is hot and humid, air-conditioner has become a popular apparatus in every household. However, this has also increased the burden to the electricity system significantly. Therefore research and development for more efficient air-conditioners to reduce the need of electricity in Summer is an important topic in the area of electrical drive today. The objective of this paper is to investigate the control characteristics of air-conditioners, and to develop an efficiency-optimized vector controlled induction motor drive that is suitable for air-conditioners. Both simulation and experiments were performed to verify the proposed control scheme.
