摘　要：弹体通过加入稳定控制回路对飞行过程中的不足之处进行补偿，达到稳定飞行、精确打击的目的。建立了弹体六自由度模型，以俯仰方向为例，根据弹体特性分别设计了阻尼内回路、姿态回路、过载回路使弹体特性能够满足工程实际要求，通过对仿真结果进行分析，发现加入阻尼回路、姿态回路、过载回路可以更好地改善控制过程中弹丸飞行稳定性，避免出现弹体动态失稳的现象，可进一步提高控制品质，从根本上提高系统抗干扰能力。

Abstract：The projectile compensates for the inadequacies in the flight process by adding a stable control loop to achieve stable flight and precise strike.The six-degree-of-freedom model of the projectile is estab⁃lished.Taking the pitch direction as an example，the damper inner loop，attitude loop and overload loop are designed according to the characteristics of the projectile to make the projectile characteristics meet the actual engineering requirements.Through the analysis of the simulation results，it is found that adding the damping loop，attitude loop and the overload loop can better improve the flight stability of the projectile during the control process and avoid the phenomenon of dynamic instability of the projectile，which can further improve the control quality and fundamentally improve the system anti-interference ability.
