| Summary: | 碩士 === 明新科技大學 === 電機工程研究所 === 96 === In this thesis, the relations between the continuous-time and the discrete-time control systems are investigated. An appropriate sampling time must be chosen to discretize a continuous-time system. The main topics of this thesis are how to choose the sampling time and what the effects of the sampling time on the discrete-time system are. The basic configuration of the continuous-time system to be discretized is prestablished by using state feedback. Then, the system is discretized without changing the state feedback gain. The selection of the sampling time to preserve the stability of the system and the approximation of the responses between the continuous-time system and the discrete-time version are discussed. Some illustrative examples are given to verify the derived results.
