Abstract

To overcome the disadvantage influence of time delay term on the TCP/AQM control system model, the paper proposed that a new AQM algorithm called SPI (proportional integral control based on Smith predictor), which combined Smith predictor and Dahlin algorithm. By moving the time delay term to the outside of control loop, SPI can eliminate the influence of time delay on the system performance, and reduce the number of the tuning parameters. The result of simulation shows that the presented SPI controller can effectively avoid network congestion, improve the system stability, and have a good performance in respect to robustness to variation of system parameters
