Reduced-Order Projective Synchronization of Hyper-Chaotic L\"{U} System and Chen System

By selecting non-zero constant as a scaling factor, we design a reduced-order projective synchronization scheme for synchronizing the fourth-order hyper-chaotic L\"{u} system and the third-order chaotic Chen system. To this end, a nonlinear synchronization controller is constructed. Finally, some numerical simulations are given to illustrate the feasibility and effectiveness of the proposed synchronization scheme in this paper.
