摘　　要：研究了光纤激光器的混沌控制问题,采用线性反馈控制对光纤激光器混沌系统进行了稳定控制,通过控制使单模激光混沌系统不再有混沌现象。给出了线性反馈控制函数的表达式,从理论上研究和得到了反馈系数的选择原则。研究结果表明:恰当地选择线性反馈控制函数和反馈系数,可以使单模激光混沌系统具有任意所需要的稳定输出和周期轨道;选择确定的控制函数和反馈系数,可以事先知道控制结果。Chaotic control for the fiber laser system was discussed in this paper. It is easy to realize stable control for fiber laser chaotic system via linear feedback control. Using this linear feedback control, the single-model laser chaotic system is not chaotic. The linear feedback control function was given, and feedback coefficients were obtained theoretically. The investigation results show that, the single-model laser chaotic system is not chaotic and has the required arbitrary stable outputs and periodic orbits choosing suitable linear feedback control function and feedback coefficients. Another more important result is that control results are made certain beforehand by assured linear feedback control function and feedback coefficients.
