Active queue management (AQM) mechanism plays an important role in network congestion control. In this paper, we propose an effective AQM algorithm, named adaptive real queue control (ARQC). In particular, an explicit congestion indicator, virtual regulating time, is designed to detect network congestion. Then by analyzing the queuing system on routers, we(More)
This paper presents a novel approach for the actuators fault diagnosis of time-delay systems by using an adaptive observer technique. The systems considered are subjected to an unknown input that represents either model uncertainty or external disturbances. At first, fault detection observer and fault diagnosis observer for linear actuators are designed. An(More)
