APD and APID Controllers for AQM
主动队列管理中的APD和APID控制器的设计*

As the supplement of the network congestion control,AQM(Active Queue Management) can effectively control the queue length and realize high throughput,so it can control the delay from end to end and guarantee the OoS of the system.In theory,many AQM mechanisms can be reduced to be PID controllers.Based on the model of PD and PID controller,two new adaptive control mechanisms,i.e. APD and APID controllers,can improve the system's stability and performance.Simulations suggest that the proposed algorithms can achieve good system performance and stability.
