| 摘 要： | 针对ATM网络的拥塞控制问题，考虑网络中的不确定性因素，借助离散滑模控制理论的设计方法。提出一种二进制ABR（可用比特率）流量控制算法．该算法利用线性矩阵不等式设计了一个稳定的滑模面，同时给出了一种能够明显减小滑模面附近抖振的离散趋近律，基于该趋近律的控制律能有效抑制ATM交换机中的队列长度和允许信元速率的振荡．仿真算例证实了所提出算法的有效性．

| Abstract: | For the problem of congestion control in ATM networks, considering the uncertainty in networks, a binary available bit rate(ABR) flow control algorithm is proposed by using the approach of designing discrete sliding mode controller. The stable sliding surface is designed by using linear matrix inequality(LMI). Meanwhile, a discrete reaching law that can obviously reduce chattering around the sliding surface is also proposed. Based on the reaching law, the control law can effectively constrain the oscillation of the queue length in ATM switch and the allowed cell rate(ACR). The simulation results show the effectiveness of the algorithm. |
