Adaptive finite-time congestion controller design of TCP/AQM systems based on neural network and funnel control

Abstract

This work investigates an adaptive finite-time congestion control problem of transmission control protocol/active queue management. By means of the funnel control, neural networks and sliding mode control, a new AQM algorithm is proposed to ensure that the tracking error $$e_{1}\left( t\right) $$ converges to the prescribed boundary in finite time and the transient and steady-state performances of $$e_{1}\left( t\right) $$ can be satisfied. The stability analysis is given to prove that all the signals of the closed-loop system are finite-time bounded. Finally, a comparison example is considered to demonstrate the feasibility and superiority of the presented scheme.
