旋转导弹制导控制系统一般采用经典比例导引进行设计,视线角速度波动大,不利于抗干扰。本文借鉴三通道导弹制导控制系统设计方法,研究修正比例导引在旋转弹中的应用,在分析修正比例导引原理的基础上,提出采取重力补偿和加速度补偿,克服所受重力及推力对视线角速度的影响。最终通过数字仿真和半实物仿真验证,采用该方法可以极大减小全程视线角加速度,有利于抗干扰飞行试验。
Guided missile control system is generally guided by the classic design, visual angular velocity fluctuations, is not conducive to anti-jamming. This article draws lessons from the three-channel missile guidance system design method to study the application of the modified proportional guidance in the projectile, based on the analysis of the modified proportional guidance principle, the proposed gravity compensation and acceleration compensation to overcome the gravity and thrust on the line of sight Angular velocity effects. Finally, through digital simulation and semi-physical simulation, this method can greatly reduce the entire line of sight acceleration, is conducive to anti-jamming flight test.
