| 摘 要： | 利用根轨迹法对变质心控制旋转导弹的稳定性进行分析，给出了变质心控制导弹稳定的充分必要条件．针对弹体参数大范围剧烈变化的特点，根据H∞控制理论，设计了H∞状态反馈鲁棒控制器．大大成小了弹体自身参数变化对制导系统性能的不良影响，从而提高了弹体的抗干扰性能。

| Abstract: | The analyses on the variable centroid controlled spinning missile were made by utilizing the root locus method. The sufficient and necessary conditions for the stability of the controlled missile were given, which plays an important role in the practical design for variable centroid controlled missile. As the airframe parameters vary acutely and widely, an H infinite state feedback controller was designed according to H infinite control theory so as to improve the anti disturbance ability of the airframe and robustness of the missile control system. |
