间歇反馈法实现单模Lorenz-Haken激光系统的周期镇定与同步∗

摘要

For the chaos existing in a single-mode Haken-Lorenz laser system, a scheme of intermittent feedback with one variable is proposed. Numerical simulation results show that with the increase of appropriate control intensity, the Haken-Lorenz chaotic system can be suppressed to period 1, period 2, period 4, period 6, and period 8. Meanwhile, the synchronization of Haken-Lorenz chaotic systems is achieved based on the scheme of intermittent feedback.%针对单模Lorenz-Haken激光系统中存在的混沌现象，提出一种单变量间歇反馈控制方案。数值结果表明，通过选择不同的控制强度，可将Lorenz-Haken激光混沌系统镇定到1周期态、2周期态、4周期态、6周期态、8周期态等。同时，利用该控制方案，实现了Lorenz-Haken激光混沌系统的同步。
