Robust finite-time $$H_{\infty }$$ congestion control for a class of AQM network systems

Abstract

This work investigates a finite-time $$H_{\infty }$$ robust congestion control issue for transmission control protocol network systems. By means of the backstepping technique, finite-time control method and $$H_{\infty }$$ control theory, a novel robust $$H_{\infty }$$ finite-time controller design approach is presented to guarantee the finite-time convergence of the queue tracking error. Furthermore, the closed-loop network system has an $$L_{2}$$ gain less than or equal to a given positive real number. Comparative simulation results show that the proposed control method performs better than the existing control approach.
