Synchronization of Chaotic System with Uncertain Functions and Unknown Parameters Using Adaptive Poles Method

Feedback and poles are very meaningful concept in automatic control. A kind of adaptive poles method is proposed to solve synchronization problem of uncertain chaotic systems with the driven and response structure. Also a whole Lyapunov function is chosen to guarantee the stability of the system and numerical simulation is done and testifies the rightness and effectiveness of the proposed method. Most important of all, this method greatly relaxs the limitation of the uncertainties which is easy to be satisfied by common chaos system because of its boundness.
