空空导弹敏捷转弯控制与仿真

The Control and Simulation of Air-to-Air Missile' s Agile Turn

文中研究了空空导弹敏捷转弯180°(越肩发射)的控制与仿真问题。提出了实现空空导弹敏捷转弯180°的姿态控制方法,得到了简化的用于姿态控制设计的姿态动力学模型,分别采用反作用喷气控制系统和推力矢量控制系统设计了导弹的姿态控制律。对空空导弹的敏捷转弯180°的飞行过程进行了仿真并给出和分析了结果。结果表明反作用喷气控制系统和推力矢量控制系统都可以用于越肩发射,在转弯过程中速度损失是不可避免的,反作用喷气控制系统可以产生的速度损失较小。

This paper addressed the control and simulation of air-to-air missile's agile turn problem (over the shoulder mission). The method to control a 180 degrees' agile turn of an air-to-air missile was proposed. The dynamics was simplified for attitude control design. The control laws were designed with reaction jets and thrust vector separately. The simulations of a 180 degrees' agile turn of an air-to-air missile were carried out, the results were given and analyzed. It can be concluded that both reaction jet control system (RCS) and thrust vector control (TVC) can be used in the over the shoulder mission. The velocity loss is inevitable and the loss generated by RCS is less than that by TVC during the agile turn.
