Design of AQM controller for IP routers based on H//sub∞/ S/U MSP
Qiang Chen, Ou Yang · 2005
This paper proposes an AQM controller design procedure for IP routers using the recently developed H/sub /spl infin// optimal control theory. We apply the H/sub /spl infin// loop-shaping technique to solve the S/U Mixed Sensitivity Problem (MSP) in the controller design. Different weight functions and their impacts on the system performance are evaluated and discussed. Extensive OPNET simulations are performed to verify the effectiveness of our designed controller.
