In this work, we propose a new sliding mode controller based on a reference model for controlling data transmission rates in a connection‐oriented communication network. In the proposed approach, we build a model of the network, which is controlled by a linear quadratic (LQ) optimal controller. Then, the sliding variable of the real network is forced to follow the reference sliding variable generated by this model. This method enables us to preserve the favorable properties of the optimal controller, such as reducing and smoothing out the initial flow rates. Moreover, once the reference model attains the vicinity of the desired state, the designed sliding mode controller is able to react more rapidly to changes in the available bandwidth, ensuring better robustness. Due to this fact, the considered controller can ensure full bottleneck link bandwidth utilization with smaller memory buffers than the LQ optimal one. This important advantage is shown both analytically, and in computer simulations

基于参考模型的通信网络离散时间滑模控制

在这项工作中，我们提出了一种基于参考模型的新型滑模控制器，用于控制面向连接的通信网络中的数据传输速率。在提出的方法中，我们建立了一个由线性二次（LQ）最优控制器控制的网络模型。然后，实际网络的滑动变量被迫遵循此模型生成的参考滑动变量。这种方法使我们能够保留最佳控制器的有利属性，例如减少和平滑初始流量。此外，一旦参考模型达到所需状态，设计的滑模控制器就能够对可用带宽的变化做出更快的反应，从而确保更好的鲁棒性。由于这个事实，考虑到的控制器可以确保使用比LQ最优控制器更小的内存缓冲区来充分利用瓶颈链路带宽。在分析和计算机仿真中均显示了这一重要优势
