摘　　要：提出一个具有较大Lyapunov指数且频带较宽的超混沌系统,并基于状态观测器同步方法对该系统进行同步研究.结果表明,该方法不需计算条件Lyapunov指数,驱动系统和响应系统间的同步时间较短,且同步效果较好,数值仿真证明了该方法有效.We proposed a hyperchaotic system with large Lyapunov exponents and wide frequency band.The synchronization of the hyperchaotic system was studied based on the state observer synchronization method.The results show that the method does not need to calculate conditional Lyapunov exponents,the synchronization time between drive system and response system is short,and the synchronization effect is better.Numerical simulations verify the effectiveness of the proposed method.
