A new synchronization controller of Chua chaotic circuit

摘要

Chaos and its synchronization are key to chaotic secure communication. The global synchronization of chaotic Chua's circuits via piecewise linear feedback control is investigated in this paper. A master-slave synchronization scheme of Chua's circuits with piecewise linear feedback control is presented at first. Based on this scheme, some sufficient criteria for global synchronization are proved and optimized. The effectiveness of the obtained criteria is illustrated by numerical simulations.
