Stability Analysis of Networked Linear Systems for Multiple Sensors with Different Packet Loss Probabilities

doi:10.1007/s12204-015-1660-5

Abstract

Abstract: A stability problem of the linear networked control systems (NCSs) with multisensor having different data missing rates is investigated in this paper. Each sensor of the multiple sensor-controller communication channels is assumed to have an individual stochastic data missing rate. The stochastic data missing is described by a Bernoulli binary distribution. Sufficient conditions are given for the closed-loop linear NCS which is exponentially stable in the mean square sense as the existence of random multiple data missing. The stability problem could be disposed by the MATLAB linear matrix inequality (LMI) tool easily. A simulation case is provided to illustrate the validity of the presented LMI approach.
