摘要

This paper investigates the distributed dynamic event-triggered adaptive neural resilient control problem for switched nonlinear multi-agent systems (MASs). A distributed switched observer and multiple Lyapunov functions (MLFs) are constructed to deal with directed switching topologies that are disconnected or paralyzed under denial-of-service (DoS) attacks. Further, by developing a switching MLFs method, DoS attacks on sampled switching signal and switched sampled errors that may compromise system stability are handled. Also, to address asynchronous switching between candidate subsystems and controllers, a new switching dynamic event-triggering mechanism and distributed event-triggered neural resilient controllers of subsystems are designed. Then, the secure leader-following consensus can be achieved and a positive constant lower bound on inter-event times is guaranteed to avoid the Zeno phenomenon. Finally, a practical example of a switched scenario from offshore ship crane-vessel MASs is proposed to demonstrate the effectiveness of the developed design strategies.
