摘　　要：在推导变质心弹头动力学方程的基础上,对该动力学方程进行简化和线性化,得到了变质心弹头自动驾驶仪的方程,当输入不同程序控制指令后,可以仿真出变质心弹头不同的飞行弹道以及弹头的机动范围,进而得出变质心弹头纵平面内可机动飞行的范围与所需控制指令频率及幅值大小之间的关系。对于变质心弹头纵平面内机动控制程序的工程设计提供了必要的理论参考依据。In this paper, on the foundation of building up dynamic equations of the moving centroid, the dynamic equationgs are simplified and linearized , and the auto-pilot of moving centroid can be attained. If different control orders are inputed, the different trajectories and maneuvering ranges of moving centroid can be simulated, thus, we can obtain the relations between the maneuvering range of warhead in vertical plane and frequency and amplitude of control orders. This researching results provide necessary theoretic reference for designing control programs of moving centroid warhead in practice in vertical planar maneuvering flight
