碩士 === 國立成功大學 === 電機工程學系碩博士班 === 90 === 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.
