In this paper, we design H∞ robust controllers for AQM based on the linearized TCP model with time delays. For the linear system model exhibiting LPV nature, we investigate the H∞-performance with respect to the uncertainty bound of RTT (round trip time). The robust controllers and the corresponding analysis of H∞-performance are validated by simulations in different scenarios.EnglishComputer simulationFeedback controlInternetMathematical modelsNonlinear systemsQuality of serviceTelecommunication trafficActive queue management (AQM)Robustness (control systems)Conference Paper10.1109/ACC.2003.1240493
