The consensus control problem of nonlinear cyber-physical systems with two-layer switching networks is investigated in this paper. Due to the hierarchical structure of two-layer networks, two-layer switching networks can simulate real networks more effectively than single-layer networks. In addition, the nonlinear component of the networks satisfies incremental quadratic constraints. An appropriate Lyapunov function is constructed to provide sufficient conditions for the node-to-node consensus problem. Furthermore, under some given assumptions and the node-to-node consensus, the complete consensus of two-layer networks is achieved. Finally, the validity of the method is verified by a simulation.
