Hybrid-triggered based non-fragile control for consensus of nonlinear multi-agent cyber-physical systems with incremental quadratic constraints and denial-of-service attacks

This paper scrutinizes the consensus problem of nonlinear multi-agent cyber-physical systems through hybrid-triggered control. Initially, the nonlinearities of multi-agent cyber-physical systems are employed with incremental quadratic constraints, which are represented by incremental quadratic matrices. It is to be noted that hybrid-triggered technique switches between time-triggered and event-triggered protocols in order to efficiently reduce the network bandwidth load. Further, with the aim of providing a resilient and secure communication, the control is formulated with gain fluctuations and the effects of cyber attacks such as denial-of-service attacks. By exploiting an appropriate Lyapunov-Krasovskii functional (LKF) and utilizing Peng-Park integral inequality, adequate conditions are acquired in terms of linear matrix inequalities (LMIs). Eventually, the efficacy of theoretical findings are illustrated with numerical simulations.
