<p>This paper investigates the cluster consensus problem of nonlinear multi-agent systems via intermittent output feedback control protocols. Unlike the traditional continuous communication method, the proposed method achieves the exchange of information at non-periodic time intervals. Then, it ensures the consensus of the groups while solving the resource limitation problem. Meanwhile, two kinds of nonlinearities contained in the MASs are considered, respectively, i.e., one-sided Lipschitz and P-one-sided Lipschitz. Additionally, by combining Lyapunov stability analysis with graph-theoretic methods, we establish sufficient conditions for achieving consensus. Finally, the simulation results validate the efficiency of the proposed strategy.</p>
