The prescribed-time intra-layer synchronization problem of multiplex networks model with different node dynamics and directed and heterogeneous intra-layer topological structures is studied. Unlike finite-time and fixed-time synchronization, this synchronization time can be preset according to user’s requirements and is not affected by the initial state and control parameters. By using the Lyapunov stability theory and the properties of the M-matrix, a sufficient criterion for prescribed-time intra-layer synchronization of multiplex networks is obtained. Finally, the validity of the theoretical results is verified through numerical simulation.
