Generalized Function Lag Projective Synchronization and Parameter Identification of a Class of Chaotic Systems with Fully Uncertain Parameters

研究了具有未知参数的一类混沌系统的广义函数延迟投影同步及参数辨识问题.基于Lyapunov稳定性定理和自适应控制方法,在驱动系统和响应系统参数完全未知的情况下,设计自适应控制器和参数更新规则,实现了一类混沌系统的广义函数延迟投影同步,同时精确地辨识出了系统的所有参数.数值仿真结果表明了该方法的有效性和可行性.

Generalized function lag projective synchronization and parameter identification of a class of chaotic systems with fully uncertain parameters was examined in the paper.Based on Lyapunov stability theory and adaptive control method,the adaptive controllers and parameter update laws were designed.Generalized function lag projective synchronization of a class of chaotic systems with fully uncertain parameters was achieved,and the unknown parameters can be identified.The numerical simulation verified the effectiveness and feasibility.
