摘　　要：研究了两种不同复杂系统的异结构混沌同步问题。分析了系统线性化条件,给出输出函数。设计一个基于时间延迟反馈(TDF)的同步控制器,实现两种异结构的混沌同步。用Lyapunov稳定性定理证明异结构超混沌同步。最后,给出系统四个分量同步误差数值模拟演化图,进一步验证了所提方案的有效性。The synchronization problem was investigated for two kinds of complex system with different structures in the present study. This paper analyses linearizing condition for the system, and gives an output function. A kind of controller based on time delay feedback （TDF） was designed, and it can achieve synchronization for complex system with different structures. By using Lyapunov Stability Theory, we proved the synchronization for the system. At last, the numerical simulation experiments were provided to further demonstrate the effectiveness of the proposed scheme.
