本文旨在探討對於多變數系統之兩種追蹤器的設計方法。一種是分散式追蹤器設計方法，另一種是狀態迴授分解追蹤器設計方法。前者是利用多變數系統之主要子系統來設計分散式控制器使得分散式控制器可以保留集中式控制系統所想要的性能。並且分散式控制器的設計與硬體的實現也比較簡單。而後者是利用高增益方塊極點假設法來設計一個解耦式狀態迴授控制器使得系統輸出可以很快追上任何參考輸入。並且閉迴路系統可以被分解成幾個子系統，在分析上也比較容易。此外，當數位再設計系統像原本連續系統一樣性能時，我們可以利用數位再設計方法來減少控制訊號的暫態響應大小和對於實現控制器硬體的複雜度可以明顯地改善。

This thesis addresses two tracker design methodologies for the multivariable system. One is the decentralized tracker design method and the other is the state-feedback decomposed tracker design method. The former is utilizing the main subsystem of multivariable system to design the decentralized controller so that the decentralized controller preserves the desired performance of the centralized controlled system. The hardware and the controller design of the decentralized control system is more simplicity than the one of the centralized control system, also. The latter is utilizing the block-pole placement to develop a decoupling state-feedback controller so that the output of system can quickly track any arbitrary reference command signal. The closed-loop system can be decomposed into some parallel subsystems so that the analysis of the closed-loop system can be easily performed. Furthermore, we can apply the digital redesign method to above-mentioned methodologies so that the transient response of control signal can be greatly reduced and the complexity of hardware implementation of the controller can be significantly improved when the digitally redesigned system is as performance as the original analogously system.
