| 摘 要： | 考虑参数未知的非自治混沌系统作为驱动系统．用自适应控制方法构造一个响应系统，使之与驱动系统的结构相同．基于李雅普诺夫稳定性理论，进一步选择适当的控制器使它们达到完全同步．当驱动一响应系统达到完全同步时，也使它们的系统参数达到一致，由此可以识别驱动系统的参数．以受迫Duffing系统和扩音器系统为例验证了本文提出的方案是有效的．

| Abstract: | Consider non-autonomous chaotic system with unknown parameters as drive system. By adaptive control, a response system with the same structure as the drive system is constructed. Based on the Lyapunov＇s stability theory, we further choose a controller to make the drive-response systems achieve completely synchronization. We will make the parameters of the response system be in good agreement with those of the drive system when the drive-response systems achieve completely synchronization. Then the unknown parameters of the drive system can be identified. The forced Duffing oscillator and loudspeaker system are taken as examples to illustrate the effectiveness of the proposed method. |
