This paper proposes a remote congestion controller with the butterfly-shaped perfect delay compensator (PDC) for time-delay compensation in active queue management (AQM) supporting transmission control protocol (TCP) flows. The butterfly-shaped PDC does not need any time-delay model of TCP/AQM network. Simulations show that the proposed controller with the butterfly-shaped PDC effectively stabilizes the TCP/AQM network even if the system includes time-varying delays.
