本文旨在探討對具有狀態飽和之串接系統其兩種觀測基底追蹤控制器的設計方法。一種是提升型數位再設計的權重切換追蹤器，另一種是結合權重切換法則與輸出－參照追蹤的數位再設計追蹤器。其中前者可以改善因系統具有狀態飽和所造成不良的暫態響應，而後者則對於一具有狀態飽和且受到外在干擾之系統尤為有效。為了要維持系統狀態在一安全之界限，吾人使用遺傳演算法來配合權重切換法則,以求出其最佳的控制器參數。主要的控制器是以前述的方法與微處理器或數位訊號處理晶片的形式為基礎來實現。另外，在每章節的最後將分別以例子來說明所提出之控制器的效能。

This thesis addresses two newly observer-based tracker design methodologies for cascaded analog systems with the state-saturation constraint. One is the lifted digital redesign tracker of weighted switching, the other is to combine weighted switching strategy and output-reference tracking digitally redesigned tracker. The former is aimed to improve the generally poor transition response caused by state constraints, and the latter is effective for cascaded analog systems with state constraints and external loads. In order to maintain state limit, we adopt the weighted switching which uses the evolution programming optimal search technique to find the optimal parameters of the controller. The main realizations of controllers are based on above-mentioned methodologies and to associate with the digital implementation of microprocessors and digital signal processing chips. Besides, illustrative examples are given to demonstrate the effectiveness of the proposed procedure.
