【Abstract】 Due to time-varying characteristics of transmission delay and dynamical variety of users, there exist severe uncertainties in ATM networks which limits 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 methods is demonstrated by simulation results.更多还原
