Abstract

We propose a general scheme to synchronize the quantum chaotic systems within a time-variant network and to identify the uncertain parameters belonging to the quantum chaotic systems. Based on Lyapunov stability theorem, in this work, the efficient synchronization controller and identification law are designed simultaneously. And subsequently, the uncertain classical time-variant network consisting of Dicke models is taken as an example in order to verify the effectiveness of designed controller and identification law. The simulation results show that the expectation synchronization among Dicke models and identification of undetermined parameters can be realized perfectly according to our scheme, which proves that the new scheme can deal with not only fixed network but also time-variant complex network.
