Abstract: An adaptive synchronization approach is proposed for complex dynamical networks with unknown periodically time-varying topological structures. A periodic adaptive learning mechanism is used to estimate the unknown time-varying coupling parameters. By designing adaptive controllers and constructing a composite energy function, a sufficient condition of synchronization for complex dynamical networks is achieved. Numerical example validates the effectiveness of the designed method.

Key words: synchronization, complex dynamical networks, adaptive control, time-varying topological structures
