Abstract

In this paper, we study global stabilization and synchronization of n-scroll chaotic attractors for a modified Chua's circuit with hyperbolic tangent function using feedback control strategy. In particular, for any given equilibrium point of the modified Chua's circuit, we design simple and explicit controllers to globally exponentially stabilize the system. Simple controllers are also designed to globally exponentially synchronize two modified Chua's circuits. In addition to the theoretical analysis, numerical simulations are presented to illustrate the theoretical results.
