Controlling Chen Hyperchaotic System

摘要

In this paper, an approach is proposed for controlling Chen hyperchaotic system with uncertain parameters based on parameter identification. The observer is applied to the identification of the unknown parameters of Chen hyperchaotic system. Two parameters of the system can be identified at the same time. On this basis, a simple controller is designed via extending equilibrium manifolds of the original system, which can stabilize the chaotic irregular states at any target on the extending equilibrium manifold. Finally, numerical simulation is given to show the effectiveness of the proposed controller design method.
