摘　　要：为了解决现代高速通信网络拥塞控制问题,采用频域设计方法,将不确定时滞系统转化为带有未建模动态边界的多不确定系统;根据鲁棒镇定及系统性能指标要求,将流量控制的网络拥塞控制设计问题转化为共同的工程混合敏感的应用问题,然后分析设计出了理想的H∞控制器。证明采用频域设计方法的拥塞控制的H∞反馈控制器,可以实现防止拥挤和提高网络应用效率的目标。实例已表明,该方法简单易用。For solving a problem on network congestion control in modern high-speed communication networks,frequency domain design method is adopted,to transform uncertain time-delay system into multiplicative uncertainty system with unmodeled dynamic boundary. According to the requirement of the robust stabilization and performance index of system,the feedback controller design problem on robust H∞ congestion control of the high-speed communication networks which based on flow rate control was converted into the common engineering application problem on mixed-sensitivity,then worked out the desirable H∞ controller by the analytic method. The H∞ feedback controller of congestion control can get the goals of preventing congestion and maximizing the efficiency of network application by adopting frequency domain design method. The method is demonstrated be simple in use and applicable by an example.
