利用两种方法研究了统一超混沌系统的同步问题.首先以全状态混合投影自适应同步方法,基于Lyapunov稳定性理论,设计了自适应控制器,理论证明了该控制器可以实现参数已知的统一超混沌系统的全状态混合映射同步.其次使用主动控制同步方法,设计了同步控制器,实现了统一超混沌系统的完全同步,最后数值仿真实验进一步验证了所提出方案的有效性.
The projective synchronization in the unified hyperchaotic system using two control method is studied in this paper.Based on the Lyapunov stability theory,the full state hybrid projective synchronization is achieved via an adaptive controller.It is proved theoretically that the controller can make the states of the dynamical system and the response system with known parameters achieve the asymptotically full state hybrid projective synchronization.An active controller is designed to achieve the projective synchronization.Finally,Numerical simulations show the effectiveness of the two schemes.
