A research has been conducted on the intermittent event-triggered output consensus of discrete-time multi-agent systems. Firstly, combined with intermittent control and event-triggered mechanism, an output consensus control protocol is proposed for discrete-time multi-agent systems. Then, an error system is constructed, based on Lyapunov stability theory, the output consensus conditions dependent on Laplacian Matrix and system gain are derived, which guarantees the intermittent event-triggered output consensus of discrete-time multi-agent systems can be realized. Finally, a simulation example is presented for analyzing and verifying the accuracy of results.
