Control Attitude Angular Velocity for High-rolling Projectile by Moving-Mass Framework

针对高旋弹头滑块控制的特点,提出了动态方程和静态方程的概念;以双滑块机构为模型,建立了动态姿态动力学方程,运用线性化手段将方程化简;并列写成标准的状态空间形式,以满意控制理论设计了反馈控制律,以达到控制俯仰、偏航角速度的目的;针对某型高旋弹进行了仿真研究。仿真结果表明控制效果明显,为实际工程应用提供了必要借鉴。

The definitions of dynamic and static equations with the moving-mass framework for highrolling projectile were proposed; the dynamic gesture equation was established based on a hi-moving mass model, which is abbreviated by linearization method; the abbreviated equation was described as the standard state space form, the feedback control law was designed according to satisfactory control theory, to reach control tracking the angle velocities at yaw and pitch rotation directions; the tracking angular velocity for high-spin projectile with moving-mass framework was simulated. The simulated result shows the proposed algorithm is effective and pro.vides a necessary reference for practical engineering.
