| 英文摘要 |
| For a class of delayed Chen chaotic systems with unknown parameters, the scheme of its exponential synchronization is discussed. Based on Lyapunov stability theory, an exponential synchronization controller and adaptive laws of parameters are designed. A sufficient condition of exponential synchronization is then given by using the linear matrix inequality technique. The proposed method is also applied to secure communications. The designed controller is easily implemented in practice. An illustrative example is used to demonstrate the effectiveness of the presented method. |
