摘　　要：建立了直接力/气动力复合控制导弹的扰动运动方程组,分析得到自由扰动运动的稳定条件和振荡运动条件,重点研究了发动机脉冲干扰力矩作用下的导弹动态特性,得到脉冲干扰力矩和导弹运动参数之间的传递函数,分析了不同阻尼系数时导弹强迫扰动的过渡过程品质,并提出等效偏量的概念和计算方法.Interferential equations of combined control missile with lateral thrust and aerodynamic was constructed. Stability condition and surge condition of free interfering movement was found by analysis. Then dynamic characteristics of the missile were researched when it is influenced by the impulse jam moment produced of attitude control motor. Transition function of missile parameter and impulse interfering moment was achieved. Transition course quality of the missile when subject to different damp coefficients was analyzed. And the concept and calculating method of equivalent offset was put forward.

关 键 词：脉冲干扰力矩 动态特性 过渡过程品质
