Abstract

This study addresses the issue of distributed fault-tolerant consensus control for second-order multi-agent systems subject to simultaneous actuator bias faults in the physical layer and deception attacks in the cyber layer. Cyber-physical threats (malicious state-coupled nonlinear attacks and physical deflection faults), unknown control gains, external disturbances and uncertainties force the failure of the existing graph theory-based consensus control schemes, leading to disruptions in the cooperation and coordination of multi-agent systems. Then, the power integrator-based virtual control is incorporated in the distributed fault-tolerant consensus to achieve unknown parameter estimations with the adaptive technique. The consensus-based robustness to lumped uncertainties, resilience to attacks, compensation to faults, and novel finite-time convergence of the neighborhood errors and velocity errors are also realized within a prescribed finite-time settling bound. The simulation is conducted to verify the effectiveness of the distributed finite-time adaptive fault-tolerant consensus algorithm.
