Distributed Adaptive Output Synchronization of Nonlinear Multi-Agent Systems Under DoS Attacks and Disturbance

Abstract: In this study, we explore the issue of output synchronization for a class of state-constrained nonlinear multi-agent systems (MASs) influenced by exogenous disturbances and subjected to denial-of-service (DoS) attacks originating in the sensor-controller (S-C) channel. Initially, we construct a nonlinear state-dependent function based solely on the restricted states to address the asymmetric state constraints. Moreover, by introducing a coordinate transformation and incorporating it into each phase of the backstepping technique, we completely circumvent the feasibility condition imposed on the virtual control signals. Consequently, a novel adaptive synchronization control scheme is formulated, which effectively manages both exogenous disturbances and DoS attacks simultaneously. Notably, the proposed control architecture not only ensures that all synchronization errors converge within a predefined small region around the equilibrium point but also guarantees that all signals within the closed-loop system adhere to the corresponding state constraints. Ultimately, the advantages and superiority of the proposed control framework are theoretically validated and practically demonstrated through a representative example.
