针对EYDFA速率方程的非线性，提出一种迭代求解算法模型。基于环形腔反馈控制方案，采用该算法模型，分析了波分复用条件下，不同泵浦功率对EYDFA 增益控制的影响。结果表明：随着泵浦功率的增加，信号增益的可控范围逐渐增大；当多个信道撤除时，随着泵浦功率的增加，增益漂移的峰值也逐渐增大。

In this paper,an iterative algorithm model was proposed for nonlinear rate-equation of EYDFA.Based on the automatic gain feedback control strategy of ring cavity,the influence of pump power changes on automatic gain control of EYDFA under the WDM conditions was analyzed using the proposed model.The result shows that the controllable range of the signal gain increases gradually with increase of pump power.The analysis further shows that the peak of the gain drift also increases gradually with the increase of pump power when multi-channel signals were removed.
