摘要：

基于主动队列管理(AQM)控制理论模型，针对PI(proportionalintegral)控制器响应速度方面的不足，在PI控制器基础上增加了归一化输入速率控制，提出了一种适应网络环境动态变化的AQM算法——P〖JP9〗I-〖JP〗R(proportionalintegralrate)控制器. 理论分析和仿真实验证明，P〖JP9〗I-〖JP〗R控制器在保证队长稳定和链路利用率的同时实现了对网络状态变化的快速响应，也可以提高缓冲区利用率.

关键词: 主动队列管理, PI控制器, P〖JP9〗I-〖JP〗R控制器

Abstract:

A proportionalintegralrate (PIR) controller for active queue management (AQM) scheme based on the linearized AQM model was proposed. PIR controller is well suited to dynamic network environments where traffics change frequently. In order to address the slow response of PI controller, a normalized input rate control PIR controller was used to speed up the responsive time under varying network conditions. Analysis and simulation results show that under varying network conditions PIR controller will have a fast response and improve the buffer utilization, and have a good perform in stability and link utilization.

Key words: active queue management, proportionalintegral controller, proportionalintegralrate controller
