Model-based event/self-triggered fixed-time consensus of nonlinear multi-agent systems

To address model-based event-triggered fixed-time consensus of nonlinear multi-agent systems with both fixed topology and switching topologies, a novel model-based event-triggered protocol is presented. In the proposed protocol, agents in multi-agent systems update controllers by utilizing estimated state values in the triggered intervals. And for reducing the burdens of bandwidth further, the model-based event-triggered protocol is extended to self-triggered protocol which does not need continuous communication in triggered intervals. It is proven that Zeno behavior is excluded. Our main contributions are giving a novel distributed model-based event-triggered protocol for fixed-time consensus and extending it into a self-triggered protocol. Finally, a couple of simulation examples are provided to verify the effectiveness of the proposed protocols.

This paper presents a novel model-based event-triggered protocol for addressing the fixed-time consensus problem in nonlinear multi-agent systems with both fixed topology and switching topologies. The protocol updates controllers based on estimated state values in triggered intervals and is extended to a self-triggered protocol to reduce bandwidth burdens. Zeno behavior is proven to be excluded. The main contributions are a distributed model-based event-triggered protocol for fixed-time consensus and its extension into a self-triggered protocol. Several simulation examples are provided to verify the effectiveness of the proposed protocols.
