Prescribed-Time Cooperative Output Regulation of Heterogeneous Multi-Agent Systems Under Switching DoS Attacks

The problem of prescribed-time output regulation for heterogeneous multi-agent systems (MASs) under DoS attacks is investigated in this letter. On the one hand, the system before and after the attack is established as a switching system, and the convergence of some or even all agents under DoS attacks is analyzed. On the other hand, a group of distributed prescribed-time observer-based state feedback controllers are designed to guarantee that the output regulation error converges to zero within prescribed-time, which can be specified by the user. Finally, a simulation example is used to verify the effectiveness of the main techniques in this letter.
