Event-triggered sliding mode control for multi-agent systems subject to channel fading

Abstract

This study considers the consensus tracking problem for second-order multi-agent systems subject to channel fading. In order to reduce the network burden, an event-triggered strategy is introduced to lessen the frequency of information transmission between agents, based on which an event-triggered sliding mode controller is designed. Meanwhile, considering that the transmission among followers will be affected by channel fading, the statistical characteristic of channel fading is integrated into the measurement function of consensus tracking errors. Both the reachability and stability of the multi-agent system are analysed theoretically, and it is also proved that the event triggering strategy can exclude Zeno behaviour. Finally, a simulation example is provided.
