Adaptive synchronization and anti-synchronization of a modified optically injected semiconductor lasers model with unknown parameters

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 controllers and the laws of parameters. The effectiveness and the robustness of the proposed adaptive synchronization and anti synchronization schemes are demonstrated by numerical simulations.
