    Abstract: 本論文中,主要是針對具參數不確定的連續和離散之奇異系統,做一個完整的分析研究。奇異系統優於狀態空間系統,可以很自然的描述一動態系統,故奇異系統廣泛地應用在電路、有界控制系統、電源系統、化學系統、經濟系統、生物學、機器人學、航空模型等其他領域。由於在實際的環境中,不管儀器再精密或是情況再理想,一定有不可避免的擾動或是參數變動的問題。所以,這些不確定因素的考量,是系統所不可或缺的。 本論文分別針對受擾動的連續和離散之奇異系統,提出投影法去求解受擾動系統穩定性分析的問題,並把結果延伸至分析奇異之延遲系統的強健穩定性,最後由給定的例子來證明我們的說法,並和先前文獻比較,得知我們的方法可以有效的降低系統保守性。 本論文的研究主要就是利用投影法,對上述的問題做一較完整的探討,我們期望能夠得到一個更精確的穩定準則。 In this thesis, the robust stability of linear continuous-time, discrete-time and discrete state-delayed descriptor systems is investigated. Sufficient conditions are derived for ensuring that the mentioned linear descriptor systems remain asymptotically stable. The presented criteria in a complex LMI manner are checked by the projection method. The given numerical examples demostrate the validity and efficiency of the proposed method.
