摘　　要：基于状态观测器方法,研究分段线性连续混沌系统的鲁棒H∞同步问题。在同时考虑系统噪声和信道噪声的情况下,构造H∞意义下的状态观测器,使噪声对混沌同步的影响最小。状态观测器的设计可通过求解特定的线性矩阵不等式(LMI)获得。对蔡氏电路的仿真表明,用该方法设计的混沌同步系统具有较强的抗干扰能力。The robust H∞ synchronous problem of piecewise-linear continuous chaotic systems is studied based on the state observer approach.Considering both the system noise and the channel noise, the H∞ observer is designed to makes the least noise effect on chaotic synchronization. The observer can be obtained by solving certain linear matrix inequality (LMI). The simulation results for Chua's circuit show that chaotic synchronous system designed by this method has strong anti-interference capability.
