| Abstract: | Based on the theory and the method of dynamical systems, the authors further investigated complex dynamical behaviors of a new chaotic system by theoretical analysis and Matlab simulation combined method. The ultimate bounds and global attractive sets of the system were obtained. Then, the unified mathematical expression of the ultimate bounds and global attractive sets of the system were obtained by the comparison theorem of differential equations and Lagrange multiplier method. Finally, Matlab simulation result verified the correctness of the theoretical results. This article provides a theoretical basis for chaos control, chaos synchronization, chaos attractor dimension estimate of this system. |
| Keywords: | chaotic systems chaotic attractor ultimate bounds global attractive set Matlab simulations |
