摘要： 针对区分服务网络的两种典型业务类型(奖赏业务和确保业务)分别进行分析和控制,应用非线性流体流理论建立区分服务网络模型,设计推导出一种新的自适应滑模控制器.先将非线性流体流模型转化为参数严格反馈的形式,然后应用反演控制理论完成控制器的设计.通过该方法设计的自适应反演滑模控制器,能够抑制系统的未知动态和不确定性扰动,使缓冲器队列长度的调节达到理想效果.在理想滑动模态下系统渐近稳定,仿真结果进一步验证了该控制器的有效性.

Abstract: Two typical services of DiffServ network are analyzed and controlled, i.e., the premium and assured traffic services. Based on the theory of nonlinear fluid flow, a DiffServ network model was developed to design a new adaptive sliding mode controller. The model was transformed into the form where all parameters are feedback strictly. Then, the backstepping procedure was employed to complete the design. The adaptive backstepping sliding mode controller designed in this way has an ideal regulation effect of buffer queue length on unknown system dynamics and uncertain disturbances and constricts them. In such an ideal sliding mode, the asymptotic stability is available. The effectiveness of the control scheme was verified by simulation results.
