参数未知混沌系统的全状态混合投影同步

Full state hybrid projective synchronization of chaotic systems with uncertain parameters

针对参数未知混沌系统的全状态混合投影同步问题,提出一种自适应控制方法.该方法基于Lyapunov稳定性理论给出参数未知混沌系统的全状态混合投影同步的一个充分条件,并证明参数估计的收敛性.通过对Liu混沌系统与Lorenz混沌系统的数值仿真,验证所提方法的有效性.

In view of the issus of full state hybrid projective synchronization（FSHPS）of uncertain chaotic systems,based on Lyapunov theory and adaptive control method,ageneral sufficient conditions for the FSHPS of identical or different chaotic systems with fully unknown parameters are presented.Meanwhile,parameters estimates convergence is proved.Numerical simulations on the chaotic system and the hyperchaotic system are presented to verify the effectiveness of the proposed scheme.
