摘要


線性時滯系統分析引起廣汎的注意已有一段時日,新的研究論文也陸 續出現在各種刊物上,但是新的方法往往是針對解決限制條件越來越多的 問題,在系統參數稍有變化時往往就造成新方法失效,而且計算過程相當複 雜.本論文的目的是運用數種方法來分析同一系統,觀察其結論是否一致, 並比較何者較易,何者較難,甚至失效;同時觀察何種方法對處理常見( General)型式的系統最為容易,何種方法可以得到較多關於系統的資訊,例 如參數變化對系統穩定性之影響等. 在本文中應用最多的方法是參數 平面(Parameter plane)和參數空間(Parameterspace)法.本論文的主要貢 獻是將時域參數對系統穩定性的影響,利用穩定邊界曲線(Stability boundary)表現出來,是參數平面法和參數空間法的延伸. 本論文是在 國科會支持下的整合型研究計劃(產業界自動控制系統改良總計劃之子計 劃三,計劃編號:NSC85-2213-E-155-026),對中鋼公司鋼板熱壓系統中時間 延遲現象,作初步基本分析方法之探討.由本論文之研究結果,可使原來系 統模式(System model)不受頻域及時域之影響,都可以分析其參數變化對 系統穩定性之影響.

The stability analysis of linear time-delay systems has received muchattention in recent years. New research papers with new methods are publishedin many magazines. However, these new methods are trying to consider systemswith more and more restrictions; the computations are often very complex. Ifthe parameters of the systems are changed a little bit, some of these methodscan not give desirable results. In this thesis, several methods are appliedto analyze the same system, then one can observe whether the results are thesame, which method is easy, which method is difficult, even fail. At the sametime, one can observe which method is suitable for dealing with general systems, and which method can reveal more information of the system underconsideration. The parameter-plane and parameter- space methods are frequentlyused in this thesis. An extension of these two methods to handle time-domainparameters is the main contribution of this thesis.
