摘要
基于Pecora-Carroll混沌同步原理和参数自适应控制策略,提出一种单参数统一混沌系统的自适应同步控制方法;推导出实现不同参数、不同初值的两统一混沌系统同步的参数自适应控制律和同步条件;研究了确定控制常数边界和范围的方法,并讨论了控制常数对同步性能的影响.理论分析和数值仿真表明,选择合适的控制常数,可实现两统一混沌系统的大范围渐近稳定同步.
Based on Pecora-Carroll synchronization principle and parameter adaptive control method, the adaptive synchronization method for the unified chaotic system with a single parameter is proposed. The synchronization control law and conditions are presented. The synchronization area of the control constants and the relations between the control constants and the system synchronization performances are discussed. The theoretical studies and simulations show that the chaotic system is global asymptotic synchronization through choosing suitable control constants.
