This paper investigates the design problem of the resilient decentralized sampled-data H∞ filter for linear interconnected systems subject to the denial-of-service attacks. A piecewise Lyapunov function-based method is first developed to determine the filter parameters and the sampled-data communication schemes. Then the obtained results are utilized to facilitate the design of the resilient decentralized sampled-data H∞ filter against the denial-of-service attacks. Compared with the existing results, the communication channels from the subsystems of interconnected systems to the filters are allowed to be independent and be compromised by different adversaries. Finally, numerical simulations on the double-inverted pendulums system and the three-machine power system are provided to illustrate the efficacy of the proposed method.
