Resilient Performance-Based Funnel Congestion Control for TCP/AWM Networks
针对TCP/AWM网络受突发外部扰动时的拥塞控制问题,提出一种基于性能漏斗的弹性控制方法,能在规定时间内保证控制性能,并通过自调节漏斗边界增强可靠性。
This article proposes a resilient performance-based funnel control approach for transmission control protocol (TCP)/active window management (AWM) networks subject to sudden external disturbances, enabling effective congestion control within a prescribed time. The proposed scheme utilizes an error transformation mechanism with a fixed-time convergence performance function, which not only enhances the flexibility in handling initial conditions but also ensures tight performance guarantees. Additionally, a novel self-adjustable funnel boundary is constructed to mitigate the reliability degradation of control schemes caused by bursty factors such as strong disturbances and highly fluctuating reference signals. These techniques are then integrated into a command-filtered backstepping framework to ensure predefined tracking performance and the boundedness of all closed-loop signals. Finally, simulations demonstrate the feasibility and superiority of the proposed theoretical approach.
