Resumen de Delayed Controller Design in Communication Networks via Positive Output Feedback

Jing Lei, Zhu-Yuan Yang, Ji-Bin Li

• This paper addresses delayed controller design in communication networks (CNs) with unstable open-loop system. Employing the Nyquist curve approach, the sufficient and necessary conditions of the gains and the delays, respectively, are obtained. The controllers are designed by using delayed positive output feedback. Some examples are presented to illustrate the effectiveness and simplicity of the designed controllers in both the time and frequency domains
