Note that random noise and time delay are prevalent in complex networks. Moreover, the topology of a network is often unknown or partially unknown.Therefore,based on the random generalized projective lag synchronization, we suggest an approach to estimate the system parameters and topological structure of delay-coupled complex networks under circumstance noise. By constructing an appropriate controller and adaptive update laws, the unknown network parameters and topological structure of the concerned networks can be identified simultaneously. The accuracy of the method is rigorously proved by the LaSalle-type theorem for stochastic differential delay equations.An example with networks of chaotic oscillator is provided to illustrate our method. The numerical results indicate that not only the unknown network parameters and topological structure can be accurately identify,but also the proposed method is robust against the time delay,the update gain and the network topology.
