摘　　要：本文主要研究了一个带有未知参数的改进半导体激光器的自适应同步和反同步.基于李雅普诺夫稳定性理论,设计了新颖简单的自适应同步与反同步的控制器,并给出了控制器的解析式和未知参数的辨识规则.选用带有未知参数的类Lorenz的T系统作为响应系统,实现了该系统与改进的半导体激光器的自适应同步和反同步.数值仿真验证了所设计的控制器的有效性和鲁棒性.This paper focuses on discussing the adaptive synchronization and anti-synchronization of a modified optically injected semiconductor lasers model with unknown parameters. Based on the Lyapunov stability theory, the novel, simple and systemic adaptive synchronization and anti-synchronization controllers are designated. The analytic expressions of the controllers are developed, and the adaptive laws of parameters are presented. Another Lorenz-like chaotic system, namely, T system, with unknown parameters, is employed as the response system to synchronize and anti-synchronize the modified optically injected semiconductor lasers model with unknown parameters by the presented adaptive con- trollers and the laws of parameters. The effectiveness and the robustness of the proposed adaptive syn- chronization and anti-synchronization schemes are demonstrated by numerical simulation
