Resilient Cooperative Output Regulation for Nonlinear Multiagent Systems Under DoS Attacks

The resilient cooperative output regulation problem for a class of uncertain nonlinear multi-agent systems (MASs) under denial-of-service (DoS) attacks is addressed in this paper. This is the first attempt to investigate the cooperative output regulation problem for nonlinear MASs under DoS attacks, and a novel distributed control scheme consisting of a resilient distributed observer and a distributed adaptive controller is proposed. Specifically, a novel resilient distributed observer in the form of an upper triangular chain of first order low pass filters is designed to estimate the exosystem state based on a composite output observability condition. Then, a distributed adaptive controller is designed. It is shown that the resilient cooperative output regulation problem for the concerned class of uncertain nonlinear MASs can be solved by the proposed control scheme. A simulation example is finally provided to show the effectiveness of the proposed control scheme.
