英文摘要：

Using the theory of fractional calculus, we studied the problem of observer chaos synchronization of two kinds of fractional-order systems. We gave the sufficient conditions for chaos synchronization of observer of master-slave systems of fractional-order system by designing appropriate observer and controller. Numerical simulations result show that the proposed method is effective.
