为提高低速滚转炮弹的制导精确,根据其弹道导引特性与控制原理,采用基于地磁测量与舵机控制为基础的三环导引控制。三环控制分别为舵面的跟随控制、地磁线圈的相位补偿控制和弹丸飞行运动的质心比例导引控制。通过蒙特卡罗打靶仿真,验证其三环控制的准确性。得出其三环控制可有效地实现三环之间的协调和稳定,并提高了低速滚转炮弹的制导精度。

In order to improve the precision of navigation and control of low-speed rolling projectile, a tricyclic control method, based on geomagnetic measurement and steering gear control, was analyzed according to the characteristic of 3D navigation property and control method. The tricyclic control consists of the rudder's follow control, the phase compensation of geomagnetic coil and the centroid proportional navigation of projectile. The accuracy of the method was proved through Monte Carlo shooting simulation. Lastly according to the analyses, we conclude that the tricyclic control method can effectively realize the coordination and stability of the three feedback controls and improve the precision of navigation and control of low-speed rolling projectile.
