摘    要:根据蔡氏电路混沌系统的特点,得出了蔡氏电路混沌驱动系统与响应系统的误差系统.根据混沌系统的同步条件,可将混沌的同步问题转化成为误差系统的稳定性问题,即使混沌同步误差系统渐近稳定以实现混沌同步控制.针对蔡氏电路混沌系统的误差系统,采用自适应无源化方法,设计了使同步误差系统渐近稳定的具有自适应功能的反馈镇定器.该控制方法实现了2个蔡氏电路混沌系统同步,仿真研究验证了该方法的有效性.

关 键 词:蔡氏电路混沌系统  混沌同步  误差系统  自适应无源化

Abstract:According to the characteristic of chua's circuit chaotic system,an error system between the chua's circuit chaotic drive system and response system is obtained.By the condition of synchronization of chaotic systems,the chaos synchronization problem is transformed into the stability problem of the error system.The chaotic error system is asymptotically stabilized in order to achieve chaos synchronization. To the chua's circuit chaotic error system,using the adaptive passivity method, a feedback controller w...
Keywords:chua's circuit chaotic system  chaotic synchronization  error system  adaptive passivity
