摘要

We propose a novel adaptive synchronization method for a class of nonlinear chaotic systems with uncertainparameters. Using the chaos control method, we derive a synchronizer, which can make the states of the driven systemglobally track the states of the drive system asymptotically. The advantage of our method is that our problem setting ismore general than those that already exist, and the synchronizer is simply constructed by an analytic formula, withoutknowledge in advance of the unknown bounds of the uncertain parameters. A computer simulation example is given tovalidate the proposed approach.
