Abstract: In this work, we research the parameter estimation and synchronization in the uncertain financial network. First, we introduce the characteristics of a typical financial system. And we design an observer to effectively estimate the uncertain parameter in the system. On this basis, we research the synchronization of the uncertain financial network consisting of several financial systems. The conditions of network synchronization are obtained by calculating the Lyapunov exponent of the network. Finally, we test the network synchronization performance using numerical simulation. This technique does not need to design the network controller or the control input, it is simple and convenient for practical application.
