In this paper, the finite time tracking control issue of the TCP/AQM system with input saturation and non-response flows such as UDP is studied. A novel AQM control algorithm is proposed by combining finite time control, prescribed performance control and fuzzy logic system. In order to obtain better disturbance suppression performance, the fuzzy logic system is adopted to deal with the external disturbance and the error disturbance generated by approximate input saturation function. The controller is designed to ensure that the queue tracking error converges to a specific region and achieve the practical finite time stability of all signals in the closed-loop system. The simulation results demonstrate the feasibility and superiority of the proposed method.

本文研究了UDP等输入饱和和无响应流的TCP/AQM系统的有限时间跟踪控制问题。结合有限时间控制、规定性能控制和模糊逻辑系统，提出了一种新的AQM控制算法。为了获得更好的扰动抑制性能，采用模糊逻辑系统处理外部扰动和近似输入饱和函数产生的误差扰动。该控制器旨在确保队列跟踪误差收敛到特定区域，并实现闭环系统中所有信号的实际有限时间稳定性。仿真结果证明了所提方法的可行性和优越性。
