| Abstract: | As to time-delay plants, by utilizing PID controllers, the design of guaranteed gain-margin and phase-margin was studied. Based on the gain-phase margin tester technique, and in the stability region of PID controllers, the gain-margin curve and the phase-margin curve were plotted, respectively. Furthermore, the regions satisfying the given gain-margin and phase- margin were identified in terms of a graphical stability criterion applicable to time-delay systems. Simulation examples show that the PID control system designed via the method in this research has a better controling effect in both robustness and dy- namic response aspects. |
