Projective Synchronization and Control of Unified Chaotic System
  The problem of projective synchronization(ps) and control are studied in modified unified chaotic system which possess partially linearity property. The desired ratio factor of corresponding subsystem variable could be obtained by state feedback control. Theoretical analysis and numerical simulations are provided to illustrate the projective synchronization and the feasibility of the proposed control method. The effect on projective synchronization caused by channel noise and parameter mismatch are investigated in detail, the results showed that parameter mismatch has more effect on projective synchronization than channel noise does, which may be applied to chaotic secure communications.
