摘要
为了增强导弹的突防能力和对目标的打击能力,提出一种基于虚拟导引点的对多枚导弹的位置、攻击角度、攻击时间和攻击速度进行控制的方法。建立了导弹与导引点的相对运动模型,针对攻击速度和攻击时间的要求,设计了导引点的圆弧运动轨迹。针对位置协同和攻击角度协同的要求,同时考虑导弹的需用法向过载因素,设计了导弹与导引点之间相对距离的变化规律。研究了基于相对误差的变距离跟踪控制器,使导弹能够以设定的变化的相对距离跟踪导引点飞行。仿真结果表明,采用该方法能够有效地实现多枚导弹在协同作战过程中的位置、攻击角度、攻击时间以及攻击速度的协同。
To enhance the penetration ability and target hitting capacity, a method controlling- multiple missiles＇ position, impact time, impact angle and impact velocity based on fictitious guidance dot was proposed. The relative motion model of the missile and fictitious guidance dot was built. Taking the constraints of impact velocity and impact time into account, an arc track of fictitious guidance dot was designed. The change regularity of the relative distance between the missile and fictitious guidance dot was designed to realize the position cooperation and impact angle cooperation under the consideration of missile＇s required overload. A tracking controller based on relative error was studied, which controlled the missile to track the fictitious dot at a variable relative distance. Simulation results show that adopting the proposed method can realize the cooperation of position, impact angle, impact time and impact velocity effectively when multiple-missiles combat cooperatively.
