| 摘 要： | 提出一种新的混沌系统控制方法，控制策略分为两个阶段：第一阶段利用混沌系统固有性质开环控制，系统状态到达预定区域后，进入第二阶段，切换至状态反馈模糊控制器。采用线性矩阵不等式方法设计了模糊控制器反馈增益。最后，通过一个Lorenz混沌系统设计实例验证了这种方法的有效性。

| Abstract: | A novel concept for controlling chaos systems is presented. The control of such systems is divided into two phases, the first of which uses open control of chaotic inherent features in itself. Once the system states reach a predefined domain, a T-S fuzzy controller is employed under state feedback control in the second phase. The LMI-based design for fuzzy regulator is introduced. The proposed controller architecture has been illustrated using a Lorenz system. The simulation result shows the effectiveness of the proposed controller. |
