Global synchronization criterion and adaptive synchronization for new chaotic system. (English) Zbl 1086.37512

Summary: This paper proposes two schemes of synchronization of two four-scroll chaotic attractor, a simple global synchronization and adaptive synchronization in the presence of unknown system parameters. Based on Lyapunov stability theory and matrix measure, a simple generic criterion is derived for global synchronization of four-scroll chaotic attractor system with a unidirectional linear error feedback coupling. These methods are applicable to a large class of chaotic systems where only a few algebraic inequalities are involved. Numerical simulations are presented to show the effectiveness of the proposed chaos synchronization method.
