Secure Consensus Control for Multi-Agent Systems with Multi-sensor Multi-rate Sampling Under DoS Attacks

Abstract

This paper studies the secure control problem of linear multi-agent systems (MASs) with a multi-sensor multi-rate (MSMR) sampling mechanism under denial-of-service (DoS) attacks, where DoS attacks prevent the transmission of information among agents. A matching mechanism is introduced in order to solve the problem that the time sequences of the transmitted information cannot be synchronized caused by MSMR sampling. A switching approach is used to characterize different modes of the MASs. Based on Lyapunov stability theory, a sufficient condition of secure consensus is given in term of linear matrix inequalities. Finally, a simulation example is presented to verify the effectiveness of the proposed result.
