A Uniform Modeling of Networked Control System with Random Delays

The modeling of networked control system is the foundation of the analysis, design, and simulation. In this paper, the main drawbacks of the current literatures related to networked control system are discussed. Meanwhile, a uniform model is developed based on the linear time-invariable plant model, including the situations in which the network-induced delays are shorter or longer than sampling periods. Considering the dynamic features of controller, noise and packets dropout, the uniform model is built in the discrete stochastic formation, and then many conveniences are presented for the controller design and stability analysis.
