Abstract: An adaptive H∞ synchronization approach for continuoustime chaotic syst ems is proposed. An adaptive controller is designed such that the global asympto tic synchronization between the drive and response systems can be accomplished w ithout noise, and the influence of noises in the response system on the synchron ization error is less than the expected level. Finally, the simulation results v ia Chua's circuit verify the theoretical results.
