Uniform Model

In this paper, modeling and stability of MIMO networked control system is considered in view of network-induced delay and data packet dropout simultaneously. Based on the assumption that the data packet dropout rate is fixed and the time delay is less than one sampling period, the MIMO networked control system can be considered as linear discrete time-delay system with rate constraints on events. Then, the uniform model of MIMO NCS is established and stability criterion is derived.

Nonlinear Networked Control System

In the nonlinear networked control system (NCS), the conventional control method is difficult to achieve good control performance, due to the nonlinear problem associated with the disturbance factors, such as network induced time delay and data packet dropout. Considering this situation, this paper is aimed to propose a nonlinear networked control system based on T-S fuzzy model, which does not rely on specific network parameters or mathematical model. The nonlinear problem and the uncertainties of network can be both processed by the designed fuzzy controller. Then this approach is applied to nonlinear motor servo system, simulation of the example model is implemented in Matlab/Simulink associated with True Time toolbox. The results show that the proposed method not only is convenient for modeling, but also upgrade the performance of control system.
