Speech title: Synchronization analysis of a fractional-order non-autonomous neural network with time delay
In this talk, we are mainly concerned with the synchronization problem of a class of fractional-order non-autonomous neural network models with time delay. By using the Mittag-Leffler function and the linear feedback control, the analytic expression of the synchronous controller is given. Moreover, a sufficient condition is obtained ensuring the synchronization of such delayed fractional-order neural network with Caputo derivatives by developing some new analysis methods and using the theory of delayed differential inequalities as well as constructing a suitable Lyapunov function. Finally, some numerical simulations are given to verify the effectiveness of the proposed results. As we all know, there has been a lot of research on the synchronization of integer (fractional) order autonomous neural network models with or without time delay. However, there is little research on the synchronization properties of non-autonomous (variable coefficient) neural network models with delay.
