摘　　要：舵机反操纵会降低导弹自动驾驶仪的稳定性,从舵机数学模型出发,分析了舵机反操纵对于自动驾驶仪稳定性的影响,给出了反操纵引起附加相位裕度损失的数学表达式,进而给出了自动驾驶仪稳定范围内舵机反操纵力矩因子的极限值,通过算例验证了结论的准确性。Actuator reverse operation decreased the stability of missile autopilot. Based on the mathemati- cal model of actuator, the impact of actuator reverse operation on the stability of autopilot was analyzed, and the mathematical description of additional phase margin loss caused by the reverse operation was pres- ent; therefore the limitation of actuator reverse operation moment factor in the scope of autopilot stability was analyzed, which was validated by the autopilot design example.
