理想姿态控制火箭弹的控制力矩

The Control Moment of Rockets with idealized Attitude Stability Control

根据理想姿态控制火箭弹弹道模型,提出了一种计算理想姿态稳定火箭弹控制力矩的方法。研究了在初始扰动、随机风、推力偏心等各项外界扰动因素作用下,实现理想姿态稳定火箭弹需要的控制力矩,分离出抑制每种扰动因素所需要的控制力矩,并对控制力矩存在饱和条件下的系统射击密集度进行了研究。

A model for calculating the control moment of rockets is established in this paper based on the model of ideal- ized control system for rockets with attitude stability.Then the control moment needed to realize the idealized attitude stability under initial disturbance,random wind field and thrust misalignment is calculated and the moments needed for rejecting each kind of disturbance is obtained.Finally.the influence of control moment with saturation on shooting den- sity is studied.
