| Abstract: | To overcome the disadvantage influence of delay term on the TCP/AQM control system model,the paper proposes a new AQM algorithm called PPI,which combines Smith predictor and Dahlin algorithm.The algorithm can eliminate the influence of delay on the system performance,and reduce the number of the tuning parameters.The result of simulation shows that the presented PPI controller can effectively avoid network congestion,improve the system stability,and have a good performance in respect to robustness to variation of system parameters. |
| Keywords: | communication technology congestion control delay system Smith predictor |
