Abstract
This paper investigates the non-fragile set-membership filtering problem for a class of discrete time-varying networked systems with protocol scheduling and hybrid cyber attacks. Firstly, Weighted Try-Once-Discard (WTOD) and Stochastic Communication (SC) protocol are utilized to allocate limited communication resources for the sensors of networked systems, and then two independent stochastic variables that follow Bernoulli distribution are introduced to characterize the replay attacks and deception attacks, respectively. Secondly, a non-fragile set-membership filter is provided by considering the impact of filtering gain perturbation on system performance. Sufficient conditions are derived in term of mathematical induction to ensure that the filtering error can be constrained within the ellipsoidal domain, and the minimum ellipsoidal domain in the sense of matrix trace is obtained by solving two optimal problems. Finally, the feasibility of the proposed non-fragile set-membership filtering algorithm is demonstrated through a simulation example.
