Stabilization of Networked Switched Systems Under DoS Attacks

Abstract

This paper studies the stability issue of networked switched systems under denial-of-service (DoS) attacks. To address this issue, the derived limitations imposed on both the frequency of DoS attacks on each subsystem and the upper limit of attack duration that each subsystem can tolerate are mode-dependent, which is more efficient and flexible than the current results for networked switched systems. Moreover, we reveal the relationship between the upper bound of the average maximum tolerable attack duration associated with the corresponding subsystem and the actual mode-dependent average dwell-time. Furthermore, we identify that the total tolerable DoS attack duration as a percentage of the system runtime in this paper can be higher than existing results. Finally, an example is given to demonstrate the effectiveness of our work.
