| Abstract: | In this paper,finite-time generalized synchronization of chaotic dynamical systems with different dimensions is investigated.Based on the theoretical approaches of finite-time Lyapunov stability theorem and Jensen inequality etc.,and by means of setting up different controllers,two kinds of schemes are proposed in theory so as to achieve finite-time generalized synchronization between general drive system and response system with different dimensions.Furthermore,the factors in the second scheme have been theoretically analyzed and proved which have an impact on the synchronization time.Finally,some numerical simulations are presented to verify that the proposed theories are correct and feasible. |
