Observer-based quantized chaotic synchronization

This paper studies an observer-based synchronization for continuous chaotic systems under information constraints. For a general chaotic master system and its observer-based slave system, which are connected by a limited capacity channel, a practical quantized scheme is designed such that the synchronization error is ISS on the transmission error, while the transmission error converges to zero exponentially. Therefore, the synchronization error converges to zero asymptotically under a finite communication channel. Finally, a simulation example is presented to illustrate the result.
