Abstract: This paper proposes an auxiliary system method for controlling chaotic and hyperchaotic systems. We can thus design auxiliary systems for arbitrary chaotic and hyperchaotic systems. An iteration control law is designed to stabilize unstable periodic orbits in the chaotic attractor. Numerical simulation of the Lorenz system and a hyperchaotic system verifies the effectiveness of this method.

Key words: chaotic system, control, hyperchaotic system, auxiliary system
