摘要
Abstract In this paper,a bidirectional partial generalized(lag,complete,and anticipated)synchronization of aclass of continuous-time systems is defined.Then based on the active control idea,a new systematic and concretescheme is developed to achieve bidirectional partial generalized(lag,complete,and anticipated)synchronization betweentwo chaotic systems or between chaotic and hyperchaotic systems.With the help of symbolic-numerical computation,we choose the modified Chua system,Lorenz system,and the hyperchaotic Tamasevicius-Namajunas-Cenys system toillustrate the proposed scheme.Numerical simulations are used to verify the effectiveness of the proposed scheme.It isinteresting that partial chaos synchronization not only can take place between two chaotic systems,but also can takeplace between chaotic and hyperchaotic systems.The proposed scheme can also be extended to research bidirectionalpartial generalized(lag,complete,and anticipated)synchronization between other dynamical systems.
