摘要
本文研究两个统一混沌系统之间的修正投影同步.应用李雅普诺夫稳定性理论,在系统参数已知和未知时,分别采用非线性反馈控制和自适应控制方法设计相应的控制器,实现了驱动系统与响应系统各状态的修正投影同步,并且参数未知时可以辨识出驱动系统的未知参数.数值仿真结果进一步验证本文控制方法的有效性.
This paper investigates modified projective synchronization between two unified chaotic systems.When the value of the system parameter is known or unknown,we use nonlinear feedback control and adaptive control methods respectively.The controllers and the parameter update law are derived by Lyapunov stability theory,which can make the states of the drive system and response system achieve modified projective synchronization.Besides,parameter identification of the drive system can be achieved simultaneously when the system parameter is unknown.Finally,numerical simulations show the effectiveness of the proposed control schemes.
