摘　　要：网络传输中存在严重的不确定性,由此限制了常规反馈拥塞控制算法的应用.利用预测控制方法,设计出一种改进的拥塞控制算法,增强了闭环系统的鲁棒性和稳定性,实现了带宽分配的公平性.仿真结果证实了所提出方法是有效性的.Due to time-varying characteristics of transmission delay and dynamical variety of users, there exist severe uncertainties in asynchronous transfer mode (ATM) networks which limit the application of traditional feedback control methods. An improved algorithm is presented based on generalized predictive control, which enhances the stability and robustness of closed-loop systems, and realizes the fairness of bandwidth allocation. The effectiveness of the proposed method is demonstrated by simulation results.
