Synchronization of a class of chaotic systems using nonlinear observers
实现混沌系统同步的非线性状态观测器方法

This paper investigates the synchronization design for a class of chaotic systems with uncertainties in which all state variables are not measured. The design makes use of an observer with a controller. Assuming the boundedness of chaotic attractors and limited cycles, the approach, which is both global and not relying on complete knowledge of the systems involved, is rigorously proved by means of Lyapunov theory. Computer simulation results illustrate the validity of the method.
