Design of a robust AQM strategy for dynamic TCP/AQM networks based on CDM

A new robust AQM strategy for dynamically varying TCP/AQM networks is proposed. The developed AQM is designed based on coefficient diagram method (CDM), which is a new indirect pole placement approach that considers the speed, stability and robustness of the closed loop system in terms of the time domain specifications. Computer simulation results are presented to compare the performance of the proposed method with those of PI and RED controllers
