摘　　要：基于状态观测器控制法,提出一种分数阶系统状态观测器,实现了2.7阶统一混沌系统的同步控制.Matlab仿真结果表明,基于状态观测器的控制方法不仅适用于整数阶混沌系统,也适用于分数阶混沌系统.利用该方法实现混沌系统的同步,无需计算系统的Lyapunov指数,在工程上易于实现,为混沌系统及分数阶混沌系统在实际中的应用奠定了理论基础.A fractional-order state-observer is proposed and the synchronization between 2. 7- order unified chaotic systems is realized based on the control method of state-observer. The results simulated by Matlab prove that the scheme is applicable to either integral-order systems or fractional-order systems. The state-observer based chaotic synchronization facilitates the engineering realization without calculating the system Lyapunov index and establishes the groundwork for the factual applications of chaotic system and the fractional-order chaotic system.
