摘　　要：运用自动控制理论分析了ＳＳ３Ｂ电力机车磁场削弱时电机电流抖动的原因，对调节系统进行了校正。经试验证明，校正后的调节系统能有效地抑制磁场削弱时电机电流的抖动。Automatic control theory is applied to analyze the reasons for motor current beat of SS3B electric locomotive during field weakening. Corrections are made for the regulation system. Tests prove that the corrected regulation system can effectively depress the beat of motor current during field weakening.
