Anti-synchronization of two novel hyperchaotic systems with four-scroll attractors which have been found up to the present is investigated in this work. Adaptive control is employed when system parameters are unknown. Based on Lyapunov stability theory, an adaptive controller and a parameter update law are designed so that the two hyperchaotic systems can be anti-synchronized asymptotically. Numerical simulation is provided to show the effectiveness of the theoretical results.
