摘　　要：考虑一个新超混沌系统的脉冲控制与修正投影同步,基于脉冲控制系统的稳定性理论,给出了脉冲修正投影同步的充分判据,由定理易知当同步比例因子α1,α2,α3,α4满足α21=1,α2=α1a3时所给同步方法无需添加控制器U,所以此方法可以看做是脉冲完全同步的推广.The impulsive control and modified projective synchronization of a new hyperchaotic system is investigated in this paper .Applying the impulsive theory ,some sufficient conditions for its asymptotic sta-bility via impulsive control are derived .It is easy to see by Theorem that if the scaling factors α1 ,α2 ,α3 ,α4 satisfied α21=1,α2=α1α3 ,then systems will achieve modified projective synchronization without con-trollers,which implies that the proposed synchronized method can be regarded as the generalization of the complete synchronization via impulsive control .
