摘要
提出了一种基于网络前端速率的单参数模糊自适应PID信元队列控制机制并对其进行了稳定性和鲁棒性分析。在3个节点的业务流模型基础上,运用OPNET仿真软件对其进行了不同工作条件下的仿真。结果显示,在所设计的单参数模糊自适应PID控制机制下,PID参数收敛较快,队列稳定性好且具有较好的抗扰性和鲁棒性。
This paper proposes a fuzzy and adaptive PID control mechanism and analyzes its robustness. Based on the traffic model of a single node, simulations are run through using OPNET software under different work conditions. The results show that PID parameters can coverge quickly: queue stability shows good performance as well as robustness.
