Abstract: The estimate of the boundedness of a chaotic system is important in chaos control, chaos synchronization and its applications. A dynamical system model of 3D chaotic system is given. The globally exponentially attractive set of a new chaotic system is investigated via constructing a Lyapunov function and optimation theory. Its globally exponentially attractive estimate is got. Numerical simulations are presented to show the effectiveness of the proposed scheme.
