Abstract: The globally exponentially attractive set of the Lorenz 84 system is investigated via constructing a Lyapunov function and optimation theorem. For this system, a three-dimensional ellipsoidal ultimate bound and globally exponentially attractive set are studied. The result is applied to the chaos synchronization. Numerical simulations are presented to show the effectiveness of the proposed scheme.
