Resilient semi-global finite-time cooperative output regulation of heterogeneous linear multi-agent systems subject to denial-of-service attacks

In this article, the resilient semi-global finite-time cooperative output regulation problem is addressed for heterogeneous linear multi-agent systems under denial-of-service attacks. A novel distributed resilient finite-time observer is first proposed for each agent to estimate the state of the exosystem by taking into consideration of denial-of-service attacks. Then, a novel distributed resilient finite-time controller is further developed. It is shown that under the proposed distributed controller, the resilient semi-global finite-time cooperative output regulation problem for heterogeneous linear multi-agent systems under denial-of-service attacks can be solved. More specifically, it is shown that the regulated output semi-globally converges to zero in finite time. In addition, an explicit upper bound for the finite convergence time of the regulated outputs is provided. Finally, a simulation example is provided to demonstrate the effectiveness of the proposed controller. (c) 2025 Elsevier Ltd.
