| 摘 要： | 研究了变质心再入飞行器的控制性能。对力矩的分析发现活动质量体配置于弹体质心处能降低相对运动对飞行器的影响,且飞行器三通道间的动力学耦合也将减轻。将活动质量体配置在弹体质心以优化变质心控制结构布局,并设计姿态控制律,比较了布局优化和未优化的姿态响应和滑块运动。结果表明:采用布局优化不仅能提高变质心控制的操纵性,改善姿态响应的动态品质,而且滑块的运动品质也得以改进。

| Abstract: | The control performance of moving mass reentry vehicle was analyzed in this paper.It was found that the influence which was generated by relative movement on reentry vehicle could be reduced and the dynamic coupling also could be declined when placing the moving mass on the mass center of body.The layout was optimized by the moving mass trim control(MMTC).The control law in vertical plane was designed.The attitude response and slider moving of layout optimization situation and no layout optimization situati... |
