Some analyses and researches are done about networked control systems (NCS) those are based on the new Smith predictor and internal model control (IMC) from the system structures in this paper. The research and simulation results show that the choice of strategy of the new Smith predictor is more flexible than internal model control, but the adjusting parameter of the internal model control is relatively...
The purpose of this paper is to investigate the impulsive exponential stabilization for the positive equilibrium points of a class of discrete population growth models with time delays. By using Lyapunov functionals, some new exponential stability criteria are given. It is shown that impulses can indeed make unstable equilibrium points exponentially stable, and when the impulses are employed to stabilize...
This paper proposes a new mathematical QoS model called LRD_Q_Model for long range dependence (LRD) multimedia flows on the basis of network calculus theory. In LRD_Q_Model, the packets of a LRD flow are regulated by the Fractal Leak Bucket model at the edge nodes of networks and scheduled by the weighted fairness queuing (WFQ) model at each router of the transmission path. We give the service curve...
