摘　　要：弹道导弹的弹性振动信号通过敏感元件馈入姿态控制系统,影响控制系统的工作,通常借助于相位稳定或增益稳定技术保证弹性振动的稳定。采用对外扰及未建模动态具有良好抑制作用的滑模变结构控制,必须解决它与滤波网络相匹配的问题。The signals of elastic vibrations are fed into the control system of ballistic missile via the attitude measurements, and it will have an effect upon the proper function of control system. Generally, the phase stability and gain stability technique can be applied to obtain the stability of elastic vibrations. As the sliding mode control is adopted, which has inherent insensitivity and robustness to bounded unmeasured disturbances, large uncertainties and unmodeling dynamics, it must match with the filter network.
