高超音速导弹的质量矩控制是通过移动导弹内部滑动质量块的位置,使整个导弹的质量中心产生偏移,并利用气动力相对于质心的力矩改变导弹的飞行姿态和攻角,最终实现导弹机动控制的一种控制方式。以弹头为例,在推导出质量矩弹头的动力学方程基础上,通过分析其方程组的特点并结合弹头再入过程中的气动、速度等参数变化规律,给出了质量矩弹头再入过程中宜采用的控制模式,为其控制律的设计提供了必要的理论参考。
The mass moment control of hypersonic missile is to shift the mass center of the whole missile by moving the position of the sliding mass inside the missile and to change the attitude and angle of attack of the missile by using the moment of the aerodynamic force relative to the centroid to finally realize the missile maneuver A control method of control. Taking the warhead as an example, based on the derivation of the dynamic equation of the mass moment warhead, the mass moment warhead reentry process is given by analyzing the characteristics of the system of equations and combining with the variation law of the parameters such as aerodynamics and velocity during the warhead reentry. Which should be used to control the design of the control law provides the necessary theoretical reference.
