Abstract :
We design an adaptive multiloop PI (proportional-integral) rate-based controller for the MIMO (multiple-input multiple-output) AQM (active queue management) router to support best-effort streaming media traffic in the Internet. Our controller design employs the DNA (direct Nyquist array) method by shaping the Gershgorin band analytically, thus allowing users to achieve good stability robustness of the MIMO AQM control system through specifying a proper phase margin.
