中文摘要
本論文探討當線性非時變的離散系統模型具有凸多邊形不確定量時,如何利用線性矩陣不等式設計動態輸出回授控制器使得閉迴路系統滿足 DR 穩定,而且其轉移矩陣的 H2 範數和 H∞ 範數小於規範值 ru 的問題。論文中根據系統是否 DR 穩定分為兩部份。在論文前半部份,我們提出 H2 和 H∞ 的分析方法(現有文獻的結果僅為本論文的特例),而且改善控制器的設計方法:在論文後半部份的內容,我們更近一步討論當系統需要滿足 DR 穩定時 H2 和 H∞ 的設計方法。本論文提出來的設計方法為線性矩陣不等式的充分條件,因此可以利用現有的軟體求解,在論文中舉數值模擬的例子來做說明。
Abstract
The thesis considers the problems of designing a dynamic output feedback controller to discrete time systems with polytopic uncertainty so that the closed-loop systems are DR stable with their transfer matrices having H2 norm and H∞ norm bounded by a prescribed value ru. The formar part of the thesis provides less conservative LMI conditions for H2 and H∞ analysis and the output feedback control of discrete system than those appeared in the current research. While the latter part of the thesis extend the current research to DR stable with H2 and H∞ design. Finally, numerical examples are illustrated to show improvement of the propered result.
