Abstract: Fault detection problem of multiple packets transmission networked systems with uncertain Markovian jump
system model is investigated. By introducing transmission matrix, we build Markovian jump system model with partly
unknown transition probabilities to describe the interaction between different packet transmissions in adjacent sampling
periods. Based on the obtained model, with the help of Lyapunov method and stochastic analysis techniques, we design
mode-dependent fault detection filter in terms of linear matrix inequalities to stabilize stochastically the augmented error
system in H-infinity framework. Corresponding results of classical Markovian jump system model and the switched system
model can be included as our special cases. The effectiveness of the proposed method is demonstrated by simulation
examples.
Key words: fault detection; networked systems; transmission of multiple packets; Markovian jump system
