• 中文摘要： 一種多級假想連續時域狀態空間方法被推衍出以設計並不明確顯示具有雙級或多級結構的離散系統，並不須要利用給與系統的特徵值，該被設計過的調整器將把閉迴路離散系統的特徵值移到複平面上單位圓內某小圓和自然對數曲線包圍面的交集區附近。基於密合在所有採樣瞬間的狀態，一種新的數位重新設計技巧被提出以找出該假想連續時域二次的調整器，此方法僅須解在每一級設計時的小階Riccati方程，一個說明性的例子被提出以說明該設計步驟的效果。
• 英文摘要： A multi-stage pseudo-continuous-time state-space method is developed for designing large-scalediscrete systems, which do not exhibit a two or multi-time scale structure explicitly. The designed pseudo-continuous-time regulator places the eigenvalues of the closed-loop discrete system near the common regionof a circle (concentric within the unit circle) and a logarithmic spiral in the complex z-plane,without explicitly utilizing the open-loop eigenvalues of the given system. Based on matching all the statesat all the sampling instants, a new digital redesign technique is presented for finding the pseudo-continuous-time quadratic regulator. The proposed method requires the solution of small order Riccatiequations only at each stage of the design. An illustrative example is presented to demonstratethe effectiveness of the proposed procedure.
