Outer synchronization between two uncertain timevarying delayed networks with diverse structures is investigated in this paper. Based on Lyapunov stability theory, we achieve synchronization between two timevarying delayed networks with diverse structures by using bidirectional coupling adaptive method. The network topology and coupling strength are indentified simultaneously in the synchronization process. Finally, Van der Pol system and Duffing system are taken as nodes to constitute networks, and simulation is performed to verify the effectiveness of the method.
