In this thesis, we will discuss how to design of controllers to satisfy required gain and phase margin specifications, and the controllers are proportional-integral (PI) controller, proportional-derivative (PD) controller, proportional-integral-derivative (PID) controller, and phase lead or lag compensator. In the procedure of controller design, it is very hard and complicated to let the system achieve our required gain and phase margin specifications, simultaneously. So we utilize gain-phase margin tester method to achieve this goal. The gain-phase margin tester method can transform the solutions of the controller into two-dimension surface, and we can find solutions on the figure. In some cases, the solutions of the controller will exceed two-dimension surface, so we utilize the condition of steady-state error to constrain the dimension of solutions, and avoid to increase the complexity of controller design. Finally, the effectiveness of the method is demonstrated by examples. en_US DC.subject 控制器設計 zh_TW DC.subject 補償器設計 zh_TW DC.subject 相位邊限 zh_TW DC.subject 增益邊限 zh_TW DC.subject gain margin en_US DC.subject controller design en_US DC.subject compensator design en_US DC.subject phase margin en_US DC.title 基於增益與相位邊限規格之控制器設計 zh_TW dc.language.iso zh-TW zh-TW DC.title Design of Controllers Based on Gain andPhase Margin Specifications en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
