摘　　要：应用比较定理和Lyapunov稳定性理论,通过设计开关周期性静态对数量化控制器以及平均时间耦合强度,实现混沌系统的完全同步。给出的充分条件推广和补充已有文献的结果,同时揭示量化效应及平均时间耦合强度与系统同步的内在规律。最后,仿真实例验证了分析结果的可行性。Based on the comparison theorem and Lyapunov stability theory,the complete synchronization of two chaotic systems was investigated by designing the on-off periodic coupling and static logarithmic controller.The obtained sufficient conditions extend and complement existing results in the literature.Meanwhile,inherent law between synchronization,quantized effects and average time coupling strength was revealed.Finally,the feasibility of the analysis results was verified by numerical simulations.
