Asynchronous filtering of MSRSNSs with the event-triggered try-once-discard protocol and deception attacks

This correspondence analyses the issue of asynchronous filtering for discrete-time Markov switched repeat scalar nonlinear systems under the deception attacks. Aiming to economize on the finite network bandwidth, a novel event-triggered try-once-discard protocol is presented. At the same time, the hidden Markov model with partial information is considered to describe the asynchronization between Markov switched repeat scalar nonlinear systems and filter. By establishing a mode-dependent diagonally dominant Lyapunov function, sufficient criteria are attained such that the augmented filtering error system is stochastically stable when this system meets an expected H_∞ performance level, and the desired asynchronous filter is designed. The correctness and validity of the proposed design method are verified by a numerical example.
