中文摘要：

针对PI主动队列管理算法存在调节时间长和鲁棒性差的缺点,提出了一种基于积分分离的内模PID主动队列管理算法（IMC PD-PID）。其突出特点是控制器参数整定方便,由于采用了积分分离的方法,使其既保持了积分作用,又减小了超调量。仿真结果表明：该算法较PI算法有更小的超调量,队列收敛速度明显加快。

英文摘要：

In order to overcome the disadvantages of the traditional PI controller, e. g. , the long time adjustment and weak robust performance, an internal model PID control with integral separate, IMC PDPID, is proposed. The key feature of the present algorithm lies in that its parameters are easily adjusted. By using the integral separate method, it not only maintains the integral effect but also decreases the overall capacity. Simulation results show that IMC PD-PID has stronger robust performance and quicker queue adjusting velocity.
