Robust fault detection for networked systems with stochastic communication delays

Investigates the problem of robust fault detection for a class of networked systems with random communication delays and norm-bounded uncertainties.The random delays are modeled as a linear function of the stochastic variable satisfying Bernoulli random binary distribution.A fault detection filter as residual generator is designed to make residual error system be exponentially mean-square stable and satisfy a prescribed disturbance attenuation level.A sufficient condition is derived in terms of linear matrix inequalities(LMI).Numerical examples illustrate the effectiveness of the proposed approach.
