摘　　要： 讨论一类不确定分数阶混沌系统的同步问题,基于连续频率分布等价模型、间接Lyapunov方法,利用模糊神经网络系统来近似未知函数,设计了一种鲁棒控制器,给出了混沌系统渐近同步的充分条件.仿真实例验证了方法的有效性. The paper deals with the problem of synchronization of a class of fractional-order uncertain cha- otic system. Based on a continuous frequency distributed model and indirect Lyapunov approach, the un- known functions have been approximated by using fuzzy neural networks. Then the robust controller and the sufficient condition for asymptotic synchronization of the driver chaos system and respond chaos system are presented. The validity of the proposed method is demonstrated by numerical example.
