Survey on Chaos control

Chaos and control of chaos are new theory and new research field of nonlinear dynamic system. The chaos is the complex and anomalous behavior of a nonlinear dynamic system. It is usual on many fields of nature. This paper introduces the generation and characteristic of chaos, the method for controlling chaos and the research progress and research idea of chaos control. Different strategies for chaos control are summarized. The idea and theory on the OGY method are introduced in detail. Moreover, pulse feedback method, adaptive methods and neural net works method are briefed. The direction of its possible difficulties are predicted. Finally this article also presents the applications for chaos control and the fields where chaos control should be further investigated.
