中文摘要：

一个二进制可得到的位率(ABR ) 计划基于分离时间的可变结构控制(DVSC ) ，理论被建议解决异步的转移的问题在这篇论文的模式(ATM ) 网络拥挤。有不确定性的一个分离时间的系统模型被介绍描绘变化时间的 ATM 网络。基于系统模型， asymptotically 稳定的滑动表面被线性矩阵不平等(LMI ) 设计。另外，能显然减少闲聊的一条新奇分离时间的到达法律也被提出。建议分离时间的可变结构控制器能有效地抑制允许的房间率(ACR ) 的摆动；在一个路由器的队列长度。而且，控制器对在系统的不确定性是自我适应的。模拟在不同情形被做。结果证明控制器有更好的稳定性；坚韧性比传统的二进制流动控制器，它因此对足够地施加二进制流动控制机理的简洁好。

英文摘要：

A binary available bit rate （ABR） scheme based on discrete-time variable structure control （DVSC） theory is proposed to solve the problem of asynchronous transfer mode （ATM） networks congestion in this paper. A discrete-time system model with uncertainty is introduced to depict the time-varying ATM networks. Based on the system model, an asymptotically stable sliding surface is designed by linear matrix inequality （LMI）. In addition, a novel discrete-time reaching law that can obviously reduce chatter is also put forward. The proposed discrete-time variable structure controller can effectively constrain the oscillation of allowed cell rate （ACR） and the queue length in a router. Moreover, the controller is self-adaptive against the uncertainty in the system. Simulations are done in different scenarios. The results demonstrate that the controller has better stability and robustness than the traditional binary flow controller, so it is good for adequately exerting the simplicity of binary flow control mechanisms.
