Robust H∞ Fault Detection for Networked Markov Jump Systems with Random Time-Delay

Abstract EN

This paper investigates the problem of robust H∞ fault detection for networked Markov jump systems with random time-delay which is introduced by the network.

The random time-delay is modeled as a Markov process, and the networked Markov jump systems are modeled as control systems containing two Markov chains.

The delay-dependent fault detection filter is constructed.

Furthermore, the sufficient and necessary conditions which make the closed-loop system stochastically stable and achieve prescribed H∞ performance are derived.

The method of calculating controller, fault detection filter gain matrices, and the minimal H∞ attenuation level is also obtained.

Finally, one numerical example is used to illustrate the effectiveness of the proposed method.
