具有不确定参数的新混沌系统的参数辨识与自适应同步

Parameter Identification and Adaptive Synchronization of a New Chaotic System with Uncertain Parameters

提出了一种新的参数具有不确定性的三参数三维自治系统,并对该系统展开了动力学分析.研究了系统的参数识别、自适应同步;设计了自适应控制装置以及参数更新机制;证明了驱动系统和响应系统在此控制器的作用下可以渐近地实现同步,且在加入控制器时,响应系统的参数能够被准确地识别.

A new three-parameter three-dimensional autonomous system with uncertain parameters was proposed and the dynamic analysis of the system was carried out.The parameter identification and adaptive synchronization of the system were studied.The adaptive control device and parameter update mechanism were designed.It was proved that the drive system and response system can be asymptotically synchronized under the action of this controller,and when adding the controller,the parameters of the response system can be accurately identified.
