摘要
讨论了不确定分数阶Chen系统的同步和参数识别问题,基于Lyapunove稳定性理论和自适应控制理论,提出一种用整数阶Chen系统来进行同步和参数辨识的方法,给出自适应控制器和参数更新率设计方法.数值仿真实现了分数阶Chen系统用整数阶Chen系统同步及参数辨识,结果表明提出方法的有效性.
The synchronization and parameter identification problem of the uncertain fractional-order Chen chaotic system is investigated. Based on the Lyapunov＇s stability theory and adaptive control theory, a method for synchronization of uncertain fractional-order chaotic system using integrate-order Chen system is proposed; a novel adaptive controller and parameter updating rule are designed. Synchronization frac- tional-order chaotic Chen system using integral-order chaotic Chen system is realized, by which the uncer- tain parameters of Chen system are identified. Simulation results also verify the effectiveness of the pro- posed algorithm.
