Stability Analysis of Networked Control System

Zijian Dong, Yongguang Ma, Wei Peng


This paper concerns the stability of Networked Control System assuming that communication constraints, time varying transmission intervals and network delays are subjected to the system. We consider the combined presence of the NCS problems. We describe the transmission intervals and delays as continuous random variables and allow for continuous probability distributions with unbounded. We consider the stochastic protocol as the switching function and the Networked Control System can be seen a stochastically parameter-varying discrete-time switched linear system. We use an approximation mathematical technique to preserve the available probabilistic information of the system and use a stochastic computational technique to result in linear matrix inequalities.
